165 running great franco, no problems what so ever.
i never ever have any data drops, but i use the 2g only setting. As i only use internet etc over wifi.

It's the radio...RIL stands for radio interface layer...

Franco, I am not an expert but I respectfully disagree. If signal issues were only caused by the RIL or ROM, then, logically, it makes no sense why some kernels have the issue while others do not on the same exact rom with the same settings and features.

For example, I currently do not have the issue with Ezekiel's Westwood kernel. But the moment I flash your kernel, it comes back. Also, our 4G phones are able to simultaneously make calls and use data. At least, on some kernels, I am able to. But, for whatever reason, on your kernel and some others, if I enable wifi tethering, wait for it to show connected, then make a call, I immediately lose data on my computer. But, if I stop the call, data continues.

To me, this issue on the Nexus is the single most annoying issue. Not your fault, Franco. I have been trying to resolve this issue for ever but cannot. Or, I can only flash some kernels, like Ezekiel's. One thing I have noticed is that the issue may be caused by DNS failing to work correctly, at least that is what my computer shows.

Sorry to keep bringing this up but could the TCP stack within the kernel cause any issues?
Also for those having signal issues is it more helpful to get a logcat or a dmesg?

I know what RIL stands for, but the RIL isn't the radio. The RIL interprets signals from the radio and send them to the ROM.

So that's why I asked if the RIL is found within the radio or the ROM. Apparently not the radio as it seems the RIL isn't updated to the correct one when switching radio. That's why GetRIL is such an awesome app.

i know it sounds weird but it helped for me: i had data drops yesterday, then flashed again the latest radio (i'm from austria, so xxla32) and then again the latest nightly (165). haven't had a single problem since then.

oh: slim 3.7 is my rom.

RIL lives in the ROM's system partition.

I am also wondering about the TCP stack as well. If it helps in narrowing down this issue, the following link on Ezekiel's thread states what he did to one of his kernels to resolve data drops, at least those associated with tethering:

I have also noticed that, no matter what kernel you run, undervolting can cause data drops as well. I recommend running kernels initially with the dev's voltage settings to see if you are getting the drops.

i would say that the ti omap processor and the samsung baseband are a fatal combination for this phone (both hardware and software components )

this phone never worked well with signal, switching signal, etc, with every rom and kernel

I couldn't agree more. Definitely thinking of switching to another phone. Fortunately, I have an upgrade available. Will just have to decide what phone to choose. Never this issue with the previous HTC 4G phones I've had.
