What ethernet speed depends on? (100m - 1000m) - Android TV General

Hi
I've bought a 'x96 x4 1000m' device recently which turned out to be a 100m one at last. I've opened a dispute for partial refund which I won, but I'm still not satisfied, need answers.
In short: What differences on the PCB shall I look for in general, if a device officially offers 100m and 1000m model variants?
Actually I did some investigation on this particular model and found this:
A test on an 1000m device. (The review is a possible proof that 1000m devices of this model do exist. I don't speak russian though and automatic translation is trash. If I put correctly together the review, the box is trash too, but that is a different story.)
A review on a 100m device.
Now the twist. (To me) both boards look identical! Both are equipped with this component. Unfortunately I'm not an electical engineer, so it is not a fact but only suspicious.
May 100m be a software limitation only? Would be justifiable from manufacturing point of view, but simply stupid from marketing perspective.

So I've learned today that an ethernet controller chip should be present on the PCB to provide gigabit ethernet. That piece of chip is missing, so having a 100m lan is not coincidence but actual hardware bottleneck.

i bought x96 x4 64GB ROM/LAN 1000, and when i tested the LAN it only has 100mbps, but i found out that it is not compatible with the network plug, that plug i plugged into wifi6 it broadcast with 5Ghz ac is 250mbps, my network broadcast is 400mbps if test with LAN 1000, if I want it to receive LAN 1000 then I have to replace the network end again, I take 1 gigabit LAN port on wifi 6 and plug it back into x96 x4's LAN port it gets 1000mbps. If you want to know if your box is LAN 1000 or not, you have to test plug the box into PC, 64/1000 with the codename in the introduction if it's X96_X4_Pro, then it's LAN 1000, and if its showcase name is X96_X4_Pro1 then is LAN 100

I've already sold the box to someone who didn't mind having 100m only. And yes, if I remember correctly it had a name X96_X4_Pro1.
Actually I've been testing it with a 10Gbps cable hanging from a gigabit port of a wifi6 router. The very same cable provides to this day gigabit connection to an older box of mine with actual gigabit port.
So yeah, everything is just correlating nicely. The naming convention of this particular box, the connection speed with a well performing cable, and of course the missing piece of hardware (gigabit controller chip).

Using Browser threw mini USB port

I do work now and than for a few WISP and the radios (Motorola Canopy Units) are programed with and Ethernet cable connected to a computer and the Canopy units and you use the web browser to set the IP's and do all the tweaking on the Canopy Units. My question is if I bought an adapter like this...
http://cgi.ebay.com/Mini-LAN-Adapte...hash=item270292780360&_trksid=p3286.m63.l1177
Could or will my Kaiser let me use the web browser in it using the mini USB and browser in the phone instead of carrying a notebook computer up a tower to tweak the Canopy Units and logging into the IP's I need on them.
I'd say no. The kaiser cannot use its mini usb in host mode. Basically the Kaiser cannot control other devices via usb, it can only be controlled.
Thanks for your reply, I guess I'll just keep on doing things the way I have to, I was hoping to not have to pack the notebook anymore.
There are adapters to add host function http://www.ratocsystems.com/english/products/CFU2U.html but they are very expensive and this particular device, I'm not sure will work with your Kaiser or Tilt.
There are other phones which you can use to control the devices, I believe the IPod is on such device, but you may want something with a little more power like the HTC Shift http://www.htcwiki.com/page/Smartphone+Guides or the newer Advantage.
The point being there are alternatives for you

[Q] MicroUSB to ethernet ?

I've an HTC Desire HD and can connect via wifi, I could connect via cable and tether a PC via the phones 3G signal etc However, I was wondering if, in the absence of USB connectivity and no wifi or 3G, would a USB to RJ45 cable be made to work? That is, having a wired ethernet connection to the phone's microUSB port. Obviously you would need an ethernet driver on the phone.
Now I don't have an immediate need for this, it's more a case of 'I wonder ...... '. I've read that USB host mode is not possible but not sure how/if that would negate being able to driver ethernet over the microUSB port. Anyone know for sure?

I think the answer is not without usb host, and the cable would need to be more like a dongle with a nic in it.

You're right of course. Doh ..... (on my part). But then you can get things such as this ... http://www.saverstore.com/product/2...NIC-1427-100--USB-to-RJ45-Network-connection- ... (first one I found - may be cr*p ).

I have seen this work using a Router with a usb port.
It requires a Linux router with enough guts to do it, Tommato/DD-WRT running, and one must fiddle with it. Essentially one uses the router to share the internet USB connection. It is probably the cheapest and most supported route.

That would be lovely though .. Ill try it later ...
Let us know how it goes.
Back in the day I had an HP iPaq that didn't have WiFi built in, but I could connect it to a wired network via a small adapter that functioned as a nic. Hypothetically you could find or fashion such a device to function over mini-USB, and then write some drivers to get it to share data with an attached computer. Just my 2c.
If you want to write drivers, you have a whole new level of complexity.
USB port of a router is a known cheap solution.
I'd have to second the OP's idea, as it does have merit. Hopefully the work on getting the USB Host working can show some results in the future....
However, I'm in the same boat, where I have a Nook Color running CM7 I use as a tablet, and an N1. I'm also on business in China a lot, and I prefer to use the NC in place of a laptop, although in some places wireless is flakey or non-existent. In those scenarios I'd rather not use the N1 as an access point using the 3G network to run data, as it adds up quick, even when using China sim cards.
It's these situations where a means to connect an android device to a physical ethernet is desirable, whether by USB or by wireless to a dongle.
This is the one device I'm testing out now is a CQR-980 from Cnet. You'll have to google it, because I can't post links.
The reason for this unit is it's size (its 3.52 (L) x 2.32 (W) x 1.06 (H) inches), and full support for setting up a secure wireless environment. If it works right, I will pre-configure it as an access point with WPA2, and it should be able to be plugged into any ethernet port in a hotel or otherwise, and I should get an IP on the NC or N1 via wireless.
If anyone else has found a better way to make this sort of setup work, would love to hear of it. The fewer devices I have to bring the better. Yet this is still better than dragging even a small laptop around.
I have seen this work using a Router with a usb port.
The Phone got to have specialized hardware to enable it to use just that USB to RJ-45 cable.
But in my experience, I could be wrong about it. Don't know what the R & D guys will cook up next.
This could make the job of having RJ45 connected to USB?

Also this seems interesting:

Will it work with an ASUS Transformer (Honeycomb 3.0)?
I have looked around a lot on the web for the MicroUSB to RJ45 Ethernet on a Droid, no luck. I have small hardware devices that have embedded configuration servers that are only accessible via TCP/IP Ethernet RJ45 ports and I normally use my netbook for that. I thought it would sure be cool to be able to access those embedded servers via my Droid2G for example, and get rid of the netbook. It seems like the phone can do almost everything else.
I've read about USB host mode etc, and the mini dongles with NIC's in them seem more promising, but I guess there has not been a big enough need for the guru's to go after it. Aparently it may available on the Android 3.x tablets but no able to backport to Android 2.x? Verizon will likely never upgrade my D2G OS.

What if you used this but also used a usb extender so you could plug in the phone cable to the usb to rj45.? Then all that would be left would be the drivers.
With the exception of cybdroid's situation I think that a little wireless ap would work great. I have a little netgear wgr101 that works great.. you connect it to a rj45 port in the motel, and then wifi from the phone or laptop.
The reason i'm on this tipic, is I was thinking rj45 to rj45 on a copier. Then I can set same subnet, and ip range with a crossover cable(or ipx on on the copier). Then I wouldn't have to use a full laptop to troubleshoot...
now i'm not an apple fan but redpark has something for the i- series of apple products to do exactly what i'm curious about... you can check it on the tech journal.
Now that I spend some time reading and thinking, I might even be able to use my little wgr101 if i figure out a hosts file in the android os to direct traffic through the router. And, if I don't have to wear out the usb jack on the device, all the better.
I think I have my problem fixed, just went ahead a posted this as it might give someone else an idea. Might be a solution that even the op enjoys entertaining... I think op#2 and frayedends are on the right track.

Extending your KF or: what to use the debug connector for

Hi all,
I already had an older post asking for what the unpopulated soldered line of pads close to the Samsung flash memory chip might be useful for. To me it's clear already that it has been used during development (e.g. from the kernel sources it looks like they used to connect an ethernet interface to those pins).
Yesterday I spent some time probing for signals with an oscilloscope. There's already good news to those who might think about extending flash memory size of the Kindle Fire: pads 1-4 are directly connected to the OMAP4's MCSPI1_{CLK,SOMI,SIMO,CS0}, pads 36-37 carry GND and pads 39-40 carry 4.2V (unregulated from battery I guess as it's also not switched off when KF is off). The MCSPI can be configured to 48MHz (according to the kernel sources) and we can start connecting SPI hardware to it. I did for fun with some tiny CAN controller I had lying around and that worked out of the box using the spidev and some generic CAN driver from the network section.
Luckily, most SDcards can also be accessed via SPI. I will also try that out soon. Transfer speeds will not exceed 6MByte/s, in practice probably only half of that, but it might be enough for those who dare to extend flash memory. While probing for signals, I also noticed that the Samsung chip seems to be accessed by a single wire only, too. I might be wrong on this, but it would certainly fit the picture as max. transfer speeds do exactly match the 208MBit/s for a 1-wire eMMC connection. Maybe someone else noticed the same already.
Unfortunately, I yet only found two other useful signals routed directly to those pads: DPM_EMU0/1 (pads 16-17). I suspect that 6 other JTAG signals are also routed there, but I can't probe for them as those pads can't be configured to be used as GPIOs.
More on this to come soon...
Best,
STYLON
I just realized that I should send out a quick warning to those that are a little less well equipped with electronics gear.
Most signals on that connector are connected directly to the OMAP4430 without any buffer. They're also from the 1.8 volt domain. That means you can't connect an SD card directly to those pins.
In order to connect an SD card you need at least a level shifter (like the SN74AVCH4T245 that is already somewhere on the board) to convert signals between 1.8v and 3.3v (that's what the SD cards expect). You may also need a 3.3v LDO and connect it to the unregulated battery voltage from that connector.
I'll do some experiments with that very soon, but just wanted to order an SD card slot (don't like to solder to SD card pads directly) and some other pieces before I go ahead.
Best,
STYLON

What's the best WiFi adapter for a PC?

I plan to drop my verizon fios service and just tether from my S4. I figured this was a good place to ask which WiFi adapter is the best for this, or at least which brand? I figure PCI is better then USB, but that's all I know.
I'm running Win7 64bit on a nice custom built rig, if that makes any difference.
Thanks!
Nobody had a thing to say?
Well, I did a little poking around and saw that the S4 has 802.11ac capability. There's only one PCI-e adapter available on New Egg that supports 802.11ac. Its an Asus brand with a nice tri-antenna stand to get the antennas away from the back of the PC box. I'll report back in a few weeks to say how it works.
Got the WiFi adapter in the mail and installed today. Only spent a few minutes fooling with it but it installs easy and appears to work well. Connection speed for forum browsing and email checking was snappy and indistinguishable from the wired fios connection.

Building a Raspberry Pi based A/C controller

We just got into a new house and the heating and cooling are done using an Atlantic R32 duct type unit. Since it is blowing in all the rooms at the same time and the fact that the wired controller with the sensor is right underneath one of the vent, we have a lot of trouble getting the whole house to a satisfying temperature.
It would be a lot of money to get a brand new system with a better room temperature control, so I was thinking I could maybe use a Raspberry Pi or Arduino instead of the wired controller to create a web interface that I could use from my phone and connect multiple sensors in order to have the temperature in each room.
With the documentation that is provided for technicians, we can see that that the wiring is made of three cables, a 12V, a COM and a signal cable. I would have expected a RX and TX cable along the 12V and COM... So I'm a bit at a loss at how to start here. It seems like the communication goes both ways since they mention a discovery phase for the remote control.
I would like to know if someone has experience with hacking this kind of device and what I could do to retrieve data frames or even discover the sampling rate ?
