Connects to local wi-fi, but can't connect to the internet. - Samsung Galaxy Tab A series Questions & Answers

Hi
I am having a problem connecting to the internet through my home Wi-Fi network on a Tab A (SM-T350). It connects to the WiFi network just fine. I can control my Harmony TV remote from the Tab A so I know it is solidly on the net. It shows up as a connected device on the router. When I try for any internet connection I get a "Server not found" message. The weird thing is it has connected to the Yahoo home page twice but I could not go anywhere from there. When I got out of the browser I was not able to reconnect. It won't sync Email either. I am using several browsers and get the same behavior all of them. No other devices are having any problem with the WiFi network, just the Tab A.
Any ideas? A web search talked about similar problems on some devices a couple of years ago. It had do with the date on the tablet being reset and some sort of sync issue. This is not the problem here.
Thanks
John

could be something wrong with your DNS

I guess you mean the Domain Name Service on the router? I can get internet access using the same router on different devices. What did you have in mind.

maybe your device isn't picking it up for some reason. you can try manually setting the DNS to 8.8.8.8 in the advanced network settings and see if it fixes it.

I tried your suggestion. It was set DHCP, I went to static, and set the DNS to 8.8.8.8 and it did not help. I did notice that when I first try to bring up a web page after connecting to the WiFi network it will bring up the current page once. None of the links will work. Also if I shut down the browser and try to re-open that same web page it will not connect.
Anyway, thanks for the idea. If you can thing of anything else let me know.

I figured it out. I went onto the router it showed a device with the correct tablet MAC address was attached. It showed the MAC address was bound to a device with an IP address that did not match the IP address the tablet was trying to talk to. I don't know how that happened, but it did. Anyway I went onto the tablet, forced a static IP and made it match the one on the router.

Wireless Problem

Done a search on various site but still no joy.
Just got a o2 XDA Mini S yesterday.But I cannot get it to connect to my wireless network at home.Its an open network, with a laptop,3 PC's,2 xbox's accessing it various times of day.All connect no problem.
My xda says my network is available,but cannot connect to it. Do I need to put in IP addresses in manually ? On the network cards section, it the SDIO WLAN wireless adapter that is used ?
Have tried allsorts,
First Question,
Is your WiFi router set to DHCP mode. If so then check that your device is also set to DHCP mode. If not change router to DHCP check that all your other devices are set to DHCP then you should automatically be allocated an IP address. A useful utility is WiFi Companion.
This scans for available networks and allows you to connect. it will also show you the IP address you have been assigned.
You could assign an IP address manually but this will have to be changed every time you walk on to another network. DHCP is better.

Thanks for the info DW, it is my router,popped round a mates last night and it connected to his network ok.
Will check what you said and the firewall
not sure by what you mean exactly by open network.
but are you using MAC address filtering?
when I got the Sony Laptop, I was so eager to get it all setup etc, that I forgot bout the filtering, it would see the network, but refused to connect.
I'm having the same problem. My Exec can see the network but not connect. I investigated it a bit more and for some reason it keeps trying to use the same IP address as my laptop. It also cannot connect to the net to update Avant Go when it's syncing (via my laptop).
I've tried connecting with all other devices switched off, to avoid the IP address conflict, but still cannot connect to the internet.
I'm pretty much stumped.
Setting the Wireless power setting for best performance was the trump for me.
On my Vario - Settings - Connections - Wireless LAN - Power Mode
Thanks for the suggestion. I gave it a try but unfortunately it didn't help.
If my laptop is switched off my Exec can connect to my D-Link router, but I cannot access any internet resources. I presume that somewhere in the settings is the solution but I can't find it.
EXCELLENT db44!!!
For some reasons setting wireless "best performance" wortked for me too. Wizard (QTEK 9100 - gray market I guess as QTEK did not register on their site for me). I will still try Opera too.
Kind regards,
Oleg.
www.nano-science.com
same thing happened to my qtek. it detected the network but could not connect and sometimes when it got connected, i still couldn't surf the net. is there anything in the settings that i'm missing? i also tried to enter the IP address manually but no luck either.
My O2 XDA Mini arrived yesterday. It sees my wireless network (as well as two others in my neighborhood) but cannot/will not connect. I've tried everything I've read above - which confirms I'm on the right trail, but...
The D-Link DI-624 wireless router is in DCHP mode. I've dropped all security for connection trials. I've put the MAC address of the XDA in the router, just in case. I cannot find the IP address of the Mini (how do you do that?), but have tried with and without allowing the router to assign it a random and an assigned IP address. My router does NOT have the default (198.162, etc, etc IP address.) so I've been careful not to blindly follow standard instructions. Of course, I have tried with specific IP addresses, default gateway (router), etc, etc.
One clue is that after trying for a long time to connect to the networks it finds, I got one error message from the XDA saying it could not be assigned an IP address from the network(s). Good clue - wish I know what it means.
There are only limited settings to check on the XDA, so I'm wondering if I'm missing something on the router. Any ideas? Many thanks.

Same Old WiFi Problem???

Having looked through the forums i'm not alone in this problem?,i have always been able to connect to the internet through my home wireless network and veiw wap sites while out & about, until yesterday i can now no longer connect to my network? All i have done is to configure it so as to be able to browse the web via gprs via a remote server as shown in a thread on this site. That worked a treat but now no wireless access, just keeps connecting but not able to connect. tried various fixes as stated in numerous threads, no joy. put it back to original config still the same. as far as i (novice) can tell it can't get a ip address of my linksys WRK54G router. haven't touched that so doubt if that is at fault. All other laptops in house still able to connect? DOH Any advice would be appreciated. Going to check on brothers network if it can connect? will let you know.
It would help if you post links to whatever advice you followed to change settings, so we would know exactly what you were trying to do.
On a side note we have a linksys router at work (fortunately not on the main network) and sometimes it refuses to let my Jamin connect for no reason until I reset it. (Pulling the power supply does the trick)
I know it is not much of a solution, but worth a shot (router configuration will not be effected) specially if you manage to connect to your brothers network.
Sorry here is link, http://forum.xda-developers.com/showthread.php?t=269023&highlight=T-Mobile+GPRS.
Also had error message appearing about ip address not being assigned, after/during activesync? fixed this. Could it be related?.
When connecting to network all details show correct in the WiFi settings page, but in the advanced tab ip is 0.0.0.0 and status assigned to network. If i tap renew nothing happens?. Hope this helps tia
Guess you would like to no how i fixed the other problem, "http://groups.google.co.uk/group/microsoft.public.pocketpc/browse_thread/thread/d6df3cc438b9ca5f/8bd321e9d0200967%238bd321e9d0200967?sa=X&oi=groupsr&start=0&num=3"
Have got it working, tried powering down wireless router - no change, thought about a hard reset, not today thanks, tried a soft reset, bingo! it works. swear i had already tried that??, thanks for help great forum.
Oops Must have been a hiccup, was still unable to surf web through WiFi, managed it once then kept getting message unable to connect, check connections. Finally sorted it.
Set up internet connection through my ISP using o2 payandgo details, but with out proxy server info. Kept gprs settings the same in My Work Network.Seems ok after a couple of minutes testing.
If anyone needs the exact settings send me a message and I will post them.

Broken network stack? IE stuck at locating...

Hi,
I tried to connect my tytn to my wifi network for the first time yesterday, and couldn't get any web pages to load.
I was connected to the router, and had an IP address assigned by DHCP, but whenever I tried to load any pages in IE, it sat at 'locating' for ages and then errored.
I thought nothing of it and thought I'd give it another try later. But since then, I get the same problem when I try to browse via activesync. The device syncs properly and is connected, but I can't load any web pages.
My first thought was a DNS problem so I've tried setting some static servers but I'm not getting anywhere. I tried 'Microsoft Network Analyzer' which gives me ticks in all the tests (even the one where it pings www.microsoft.com, when I can't browse to there).
I'm now thinking that when I'm connected via activesync it's still trying to use the wifi connection somehow (even though it's turned off). In the network adaptors, wifi is set to DHCP but has an ipv6 address in the box under static IP (odd, as my router doesnt use ipv6).
I'm pretty lost now. I could do a hard reset but I've got a feeling I'd end up in the same place when I next try to get wifi to connect at home.
Any ideas?

Check your connection settings. Some carriers have proxies enabled for your GPRS connection. If you have proxy active, you will not be able to connect through a router. AT&T does this, for example.
Yep, that was it!
My GPRS was set up under 'My Work Connection', and had a proxy server. I disabled the proxy and activesync started working.
So I completely cleared out the 'My Work Network' connection, and added a new one for my providers GPRS which made activesync work. I then set the preferred networks to Work first, then GPRS second, and everything works.
Thanks

Wifi but no Internet

Since I bought the HD2 before 2 month and after 2 Rom upgrade I still have the same Wifi problem. I can connect to my home network and the Router can see the HD2 but I can not connect to the Internet through the Wifi. All other computers and PS3 connect just fine. Ip adress seems also ok.
Please help ?
I did have the same problem a while back, and it occured after I used the wifi router. Have you ever used that, even just to try it?
No I never tried the Wifi Router even once and changed rom twice.

Probably not the same issue then. For some reason I had it trying to give me a static IP address that my router wouldn't allow (I've got MAC forwarding on my router to make sure that nothing other than the 4 things I have can connect to it).
When you connect to the wifi, can you open the router admin on your HD2?
Thanks for your help. No I cannot access the router from the HD2, could it be a proxy issue. I am not using a proxy for the internet

No worries mate - I hope I can help!
It's not a proxy issue, if you're not using a proxy server. Could you try this and let me know how you get on?
Start your wifi connection
Go to all settings, connection, wifi, wireless networks, network adapters tab
Select the Broadcom DHD adapter
It should be set to use a server assigned IP address, not a static one. It probably is, but it's worth checking.
When I open Wifi settings I can only open advanced no wireless networks or network adapter tab. How do I get there ?

After you've started wifi, go to the settings tab, menu and all settings. Then carry on the instructions in the last post.
Found the all settings, the DHD adapter is set to server assigned. Any other ideas ?
...
Well i think we have the same problem.. If you try to connect your wireless, do you get the failure after pressing get IP: Cannot obtain serverassigned IP....
http://forum.xda-developers.com/showthread.php?t=627654 my thread was this..
I found out that if i you go under WIFI>ADVANCED>press on the NETWORKCARD under the field "SSID"> then go to the networkcard>Broadcom 802.11 DHD network adapter>remove the pin in use serverassigned, and write a static ip: example: IP: 192.168.1.23
UNDERMASK: 255.255.255.0
STANDARDgateway: 192.168.1.1
That helped for me, though i cannot use that fix because my college wont accept the static IP. so it works for like 2 mins and then it disconnect. hehe.
Heh - that would be pretty much my next suggestion.
Try a static IP address and see if that works. It's not a long-term solution, but it would determine whether it's your phone or the router that's having the problem.
Last time I set a static IP address, I liked it and left it like that, but I found (after a couple of days with no internet access) that it tries to assign the same IP address when you use your data connection for internet access. Your service provider is very unlikely to allow you to use the same IP address, so you probably can't connect.
Like I said, it's a test to see if you can connect - not a solution.
Do you know what IP addresses your router will allow you to use? Do you have a specified range of addresses, for example?
I have this exact same problem. I can connect to wifi networks at home, office, etc... But no network access. It connects to the AP's, gives me an IP Address, but I can't ping anything!
This thing gets more and more frustrating daily.

It also happened to me. Turns out it was the router I was using. I bought a new one earlier today and problem solved!
Hi!
I got a d-link dgl-4300 router, and had problem getting a IP adr. from it. When I gave my HD2 a static IP it worked, but very slow. After I changed from DHD network adapter to NE 2000 compatible ethernet driver it get IP from router and I can browse internet through wifi fast. Maybe it can help u 2.

Wi-Fi router

All
I have my htc setup to both internet sharing and Wi-Fi connection on my work PC with a lan connection. On both of these connections e.g. wired USB and wireless i can get the internet for about 3 minutes then it stops working. Is there some sort of block? I did see a while back that the WiFi app has no restrictions...
Any help would be superb.
Cheers
Baker0
Thats a little odd, there is certainly no block and I have had the wifi router running for a good 30-40 minutes without failing.
what part is failing, is the phone no longer running the wifi router, or is the pc no longer getting internet on that network connection?
If you need help on how to find this info just reply and I can walk you through some more diagnostic steps.
The phone is still running just the internet stops on the machine. I have to stop the wi fi on the phone then start again then connect. I think it might be t-mobile but the internet on the phone is fine
are you in the uk?
if you connect your laptop to the phone via the wifi router you should be able to right click the network logo, click on status and view the wifi network info, it should tell you in there if it has internet access on that network connection.
If you try this again and when it fails check this status window and see if windows is seeing an internet connection or not?
when the net fails again try and visit http://72.14.203.100/ (this should be the google homepage) if you see google then there is a dns problem if it still says network timeout or failed to connect or something like that then we will have to dig further.
LOL thanks for your help. I am in the UK. ive been working in IT for the last 12 years and I know and have done the test, its not the machine it has something to do with the phone or t-mobile network
Sorry to hijack your thread a little, but I'm on the T-Mobile Network in the UK too (except I'm using a Touch Pro with a custom ROM), and although I can make connections from the PC to websites using the IP address, the DNS isn't working so I can't resolve domain names.
Any ideas?
Cheers,
Steve.

It must be the phone then since I do use wifi router, I am on t-mobile and in the UK and I do not experience this :S
I seem to be saying this more and more but maybe you should try a hard reset and see if that fixes the problem?

This is likely an issue with the way your machine has been setup to connect to the wifi network. Try visting the properties of the network and vieing the dns settings for the tcp/ipv4, It should be set as Obtain DNS server addresses automatically. If it is set like this then try setting it too 8.8.8.8 and 8.8.4.4 these are googles, dns servers if this works for you then you could stick with this or do some further digging as to why you are not getting the dns server addresses automatically like you should be.

Setting the DNS entries to Google's makes it work, but attempting to get the DNS Server's automatically leaves me with no ability to resolve domain names. How strange?
Thanks for the workaround, not sure where to start looking to fix it properly.

Hey guys,
I am new to this wifi router thing and got the following questions:
1. To be able to use it, you must have data connection with your provider. Am I right?
2. By any chance, can I use this system by using a sim taken out of a prepaid mobile broadband dongle and inserted into my device (htc touch HD)?
3. Once I get connected can I surf the internet/check emails etc from within the device itself without the need to use a laptop?
Please don't mind these basic stupid questions.
cheers
