[Q] DHCP superscope and Android - Networking

Hi All
been struggling with this issue for a while.
I am connecting my Samsung Galaxy S based Android GingerBread 2.3.2 to a complexed LAN Environment
the DHCP server has a SuperScope:
while the DHCP server is in a 100.100.0.0/24
it gives IP addresses in 100.100.1.0/24
I.E.:
IP 100.100.1.75
SM 255.255.255.0
GW 100.100.0.254
while by default it wont allow browsing A Cisco router allowing the device to route between subnets and to the web through the Router (GW)
It is working just fine for many PC's, Macs and Iphones.
After connecting with Wifi , and recieving an IP address I cannot reach anything out of my 100.100.1.0/24 subnet
If i set a static IP in 100.100.0.0/24 (say 100.100.0.75) it will function perfectly.
I know Iphones had this problem in OS 3.x.x and it was solved in OS 4.x.x
I can modify anything i want in the DHCP server or in the Android device
Any Idea anyone?

XDAIIs wifi aaaarrrghhh - I wanna break it

into teeny weeny little pieces.
I feel so much better now!!
Anyways...I have a wireless home network up and running and would like to connet the xda to it.
I can connect to the router no probs but IE cant connect to the web. it says "the page you are looking for cannot be found".
Any ideas why I can connect to the router but not to the web?
Cheers folks - thanks
I know how you feel. There are a couple things you have to do.
First check that you have selected to connect via "work".
Then ensure that the IP address shown is in the range of 192.168.0.X
had no problems with my wifi on my home network, as ale210p said, I think it's with the way your connect via "work" or "ISP" is configured
hiya folks
thanks for coming to my rescue..hopefully i can get this thing on the road.
- in connections - advanced - select networks. both selections are set to "my work network"
- in configure network adapters - network adapters. the "my network connects me to" dropdown is selected to work.
- where can i check my ip address on the device?
Alhtough I am connected to my wireless network as that what the wireless LAN manager says?
any ideas guys?
many thanks
Is your internet provider checking the MAC address? my provider checks for the MAC address and hence I had to register my MAC address first with the provider.
I'm pretty sure my ISP isnt checking my MAC address as my PC and other computer on the network work fine with regards to internet access and I never gave the MAC addresses to the ISP.
However, my modem router does have mac filtering enabled. I have copied the MAC address of the xda to the allowed list. However I've also tried to turn this filter off and the result was the same....I still could connect to my home wireless network but had the same error message when trying to surf through pocket IE.
Any other ideas on why I can connect to the network but IE wont let me surf?
thanks again
I'm having exactly the same problem as Richard. What I don't understand is, I can drive around and find free residential wireless hotspots and surf the net , but I can't do it on my own WLAN!
IP info OK?
These symptoms could indicate that vital IP info is missing on your XDA.
Does your XDA get an IP address + gateway address + DNS server address from the router's DHCP server? Use vxIPConfig to determine this http://www.cam.com/windowsce.html
I know for a fact that many times (not always) my QTEK 9090 does NOT get the required IP info from my SMC Barricade 2804WBR b/g wireless router, so I started using fixed addresses on my QTEK.
If I use DHCP, many times I can connect to the router but am unable to access the internet... Because the QTEK has not received an IP address/gateway address/DNS server address in those cases. Fixed addresses always work.
whoa
thanks for the advice. i installed the app. rubbed the sticks together and there were sparks i tell you!!! but what does it all mean?
the ip address is 169.254.84.245
subnet mask 255.255.0.0
dhcp server 255.255.255.255
im no tekkie so am not sure what the above means? does it provide any clues?
thanks for the advice so far
just an update
i manually inputted the ip address assigned to my xda by the router as i have dhcp disabled on the router.
nonetheless it sill doesnt let me connect to the net but i can connect to the wlan?

Fixed IP address is good, but have you also put in the gateway address and DNS server address? Normally the gateway address + DNS server address = router address.
If your routers IP address would be 192.168.1.1 (quite common address), then your IP address could be 192.168.1.2, gateway address would be 192.168.1.1 and DNS server (name server) address also 192.168.1.1.
BTW; this:
the ip address is 169.254.84.245
subnet mask 255.255.0.0
dhcp server 255.255.255.255 <========= !!!!
means that DHCP didn't work!
I suppose that when you state "connect to the wlan" you mean that you can 'see' machines on your local network? Or what? That would make sense because you wouldn't need a gateway address and DNS server address for that normally (broadcasts).
siliconaddict....you're a genius!
finally it works, it works i say.
fantastic.
thanks to all for the advice and feedback - much appreciated.
can i stoke the fire and ask how i can sync via wifi as well?
never done it myself, but here is a guide
I have never synced over WiFi myself, but here are some guides:
http://theillustratednetwork.mvps.org/WM2003/ActiveSync/WM2003ActiveSyncConfiguration.html
http://forum.xda-developers.com/viewtopic.php?p=132820
Please note that the next version of Activesync, version 4, doesn't do syncing over Wifi anymore...
Good luck!
Sorry to be a complete noob, but:
1. How do I find out the IP Address of the XDA (Is it in Wireless LAN Manager, under "current config" and "IP:"?)
2. My Netgear USB WLAN is showing an IP of "0.0.0.0" (on command prompt >> ipconfig) How do I change this?
Thanks
Q & A
A 1: On your PDA use Use vxIPConfig for this http://www.cam.com/windowsce.html. Unfortunately the OS doesn't have a standard utility for it, like 'ipconfig'.
A 2: Does your router hand out IP addresses at all? Or: is DHCP enabled on your router? If true, do you have the correct drivers loaded for that USB NIC? In Device Manager how does it look? Yellow exclamation mark? Can you post the output of 'ipconfig /all'.

DNS no server specified error on all wifi activity - HTC Wizard

i must have jacked something up. first i could not get a wifi connection at home, then i flashed the firmware on the device and asked it to use the mac to connect with static IP and now the pda browsers cannot get any DNS info
netfront states no dns server specified and wireless router log states DHCP Discover no response.
must be a setting somewhere i'm missing.
wireless laptop and wired pc working fine
you can really just use the ip of a known dns from the device too
all dns servers should respond from all devices asking for the ip given the hostname
setup
cable modem to wired linksys router (DHCP on) - DI-524 wireless router connected to wired router (DHCP on)
when you say 'known IP from device' you mean the wireless router? Do you mean have the wireless router give the PDA my ISP's DNS IP?
if so what happens to my ability to browse the LAN since the devices IP is now out of the scope of my LAN
SORRY I THINK I MEAN the error is
<< DNS Discovery no repsonse. >>>
basically no DNS server found when browsing with the PDA when connected to WLAN.
PDA is ok browsing when I connect to work routers. I'm getting IP ok from home wireless dlink router but router cannot give the PDA a DNS server.
ps- wireless laptop ok for DNS connecting to the same wireless router so i'm thinking the firmware update made the dlink not like the PDA
update- i think it's the device and a setting.
now i cannot get to the internet through netfront or ie at work connected to wifi router. same error
DNS no server is specified
can get anything by IP, is wm5 wifi challenged for internet access?
any takers?

Strange issue with IP address getting same IP as other computer.

My configuration is two routers, one as the gateway, and another as a client bridge (bridged wireless-ly - obviously). I have 1 computer after the bridge with IP 192.168.1.8 (static). When my MDA is on, it grabs that same IP address as the other computer. I can surf the outside world, but when I try to access my other computer, it's hosed.
any ideas?
Not sure if this matters, but I've got DD-WRT (linux) on both routers.
Other laptops used connect fine and are assigned they're own IP.

Set the IP to either outside the dynamic IP pool range or give another static IP.
Yeah, what subzero5 said. Either change the static IP to one out side of your DHCP range or if your DHCP is set for the full subnet then change your dhcp range to a smaller one. Say 192.168.1.100 to 192.168.1.150. In most cases you don't need your DHCP so large. Some routers are defaulted to use the entire subnet which is 255 host addresses. Also make sure that dhcp isn't enabled on both routers.

Something for CONFIGURE WIFI Profile in HD2 ?

Hi.
I need about a software, that allow to set multiple WIFI profiles, because in my home i need to SET MANUALY HD2 WIFI with net adress (192.168.1.1 etc.), but when i go out, i need to catch FREE WIFI SPOT so i need to set rapidly WIFI Configuration with AUTO IP (and when i'm at home, return to Manual Adress).
I had tried WIFI Profiles, but i can't understand how i can put AUTO IP ADRESS there.
Please help me !
Compliments for great site !
There is a program called Wifi Monster, have not explored it a lot, but sounds like it might do what you want ...
Just search for it ....
Hope it helps ...
i'm curious about why you have to use a static IP for your HD2 at home. you can set your home router for DHCP (just like the rest of the WIFI hot spots you like to connect to). if assigning a specific IP to your HD2 or to other machines on your network is important, why not use "static DHCP"? static DHCP is configured in your router and will ensure that each device gets the same IP address every time.
i have configured my home router so that 10 IP addresses are available for machines. the first 5 IP addresses are assigned to specific machines using static DHCP. the rest of the slots are available for guests and friends who occasionally bring their laptops/smartphones to my place and need to get on my network. the router works intelligently by reserving the static DHCP IP addresses only for my specified machines and uses the rest dynamically for unspecified machines.
on top of all this, i have MAC address filtering to keep a tight ship.

Maybe he needs a static IP for Work, some places still use statics ....
Thanks ASCIIker & WATCHER64
I'll try all your suggestions, however the first work fine, i'll fix MANUAL ADRESS on DHCP and put AUTO on HD2.
All work fine now, but i'll try also WIFI Monster when i need only MANUAL ADRESS on my ROUTER.
Thanks to ALL !

[Q] DHCP with Gingerbread issue

Here is the shakedown
Have a full Windows 2003 Native domain environment. DNS, DHCP etc. Verizon Fios ISP with Actiontek Wireless router. DHCP has been disabled on the router. While Evo was running on “Froyo” WIFI was working fine. It would obtain a lease from the WIN2003 DHCP server and access local and Internet resources. After applying the “gingerbread” update external access is not available, (google, msn etc), Local works fine. The IP obtained is from the production scope (192.168.1.XX). If I statically assign an IP from that scope it will work. Any thoughts??
anyone? bump
