Realtek RTL8185 chipset with weak signal only in #!

sledd · 2012-06-17 03:04:33

So, turns out I have had two hardware incompatibilities since installing Statler. You lovely people helped me fix the sound issue I was having by installing the backports kernel.

Now, though, I'm running into connectivity issues with my NIC. I have a Windows 7 partition on here, and under that boot, I'm fine. I get wonderful speed for the distance I am from my router, and thusfar, I've yet to have my connection drop from timeout that wasn't due to something happening to the router. Now, in #!, though, I can't get a signal from my router. The thing fails at authentication, for some reason. It used to connect, very briefly, in the beginning, so this NIC has seen connections under #!, however, currently, I'm getting authentication errors in net-manager (the default in #!, which is xfce?) and in wicd, so I'm not sure how to approach it.

And yeah, the wpa passphrase is correct. I don't know really if there's an issue with WPA authentication and my NIC on #! or if I'm dropping packets due to #! or what. Can I please get a little help?

Some important returns:

Stupid question first: Do you use both network-manager and wicd?

I'm getting authentication errors in net-manager (the default in #!, which is xfce?) and in wicd, so I'm not sure how to approach it.

You should use exactly one network manager (preferably the default network-manager for future troubleshooting). In the past #! didn't allow to have 2 different netmanagers running, this has unfortunately changed since it moved to Debian.

I installed wicd after net-manager wasn't working. Wicd at least told me that it was failing AT authentication, or led me to believe as much. I've run each separate from one another when testing, and both give the same authentication error return.

One of the two needs to be completely removed (sudo apt-get remove), just wanted to clarify.

Also post output of

lspci -n

to verify the [vendor:product] tuple.

You could also try to eliminate network-manager from the equation:

@sledd
Interested if machinebacon's solution was of help...

if (machinebaconSolution != betterSignal ) {
  SeeIf_it_is_BrowserRelated
}

....... Geeky levity aside..Try various sites a note the speed of load.. Google is general a fast load..
....... Not sure what browser you are using but if IceWeasel / Firefox you can speed it up with these

about:config in the address bar and hit Enter.
