RTL8188CE Bad Connection, Intermittent Drops, Installed RTL Drivers?

[R. McC]

Swapping out firmware didn't have any effect for me. If anything, the other firmware options (U and U_B) offered worse performance than the main one.

I've been contributing to this bug on the matter. For what it's worth, the exact same symptoms are also present on a Ralink USB adapter.

The big clue to look for (at least for me) is a line talking about "Reason 6" in your syslog.

I continue to have no success with connecting to either my home wireless network (to which my other ThinkPad, using iwl3945 connects without issue) or the wireless network on the train. However, I can connect without issue to my work wireless network (thank goodness, since this is my work laptop...).

I continue to see the "Reason 6" errors.

I had to move back to the original firmware. The U_B firmware was worse than the original. I'm still having issues, but not as bad as before. If anyone has an update on a real solution, i'd love to hear it.

Nothing new, but I have the same issue.

Thanks, Simon. I'll keep an eye on that thread, too. So far, it looks like all the same steps everyone has recommended, but with no success. Still no progress over here, either.

I am still having connectivity issues.

The weirdest one is that when I am connected just fine, and shut my laptop, then come back online, it won't reconnect to the same WiFi. It probes the airspace/network and finds it, but can never authenticate.

This issue is driving me NUTS!

I can't use a laptop functionally without the WiFi as well.

I'm almost ready to pay a developer to take a look at this. Is there a way to do that?

/bump still trying to figure this out!

And now August, still no solution.

I still have this issue, though mine is in reverse. If I am hard wired to a modem, (3 different 2 new) data flow slows to a crawl, site(s) dump me saying "lost connection" etc ... as one cause.

For instance:
One site might be a backgammon game, another will be banking. The banking site times me out, backgammon site says "lost connection"

If I am connected using a neighbors wireless connection, all is well. No router, or I would try this at home with one.

Realtek diver page will not allow me to D/L, it says "not allowed to view page". (all d/l sites on realtec).
I am still looking to d/l the latest PCIe FE Family Controller driver. From reading this thread it doesn't look as if a new and improved driver will help.

Any new developments on this issue?

This rather interesting.

I ordered a Realtek 8192CUS from ChinaVasion (pico USB, so super small) in the hopes that I could just use an external WiFi adapter and forego the internal one I have. However after tinkering with it I causes my Ubuntu to not even boot even more (weird huh?).

So I reinstalled 64bit Ubuntu with updates, and now my internal WiFi works! I haven't had alot of time to play with it, but so far it has worked fine (even after suspend/resume). Maybe it's a kernel thing?

Current info for my setup with working RTL8192cfw:

Note, the following is with my phone basically five inches away, however before I couldn't get it to connect at all with any reliability:

If there's anything I can do to help others please let me know.

I will report back on reliability as well.

Best of luck!

The Launchpad bug has seen some more activity of late, with the release by RealTek of a new set of drivers (version 0007.*). While these new drivers have resolved the issue for some, I continue to see the same issues as before (frequent Reason 6 deauthentication leading to ~10% packet loss and terrible overall connection fidelity, despite strong signal strength).

I'm now using 12.10 x64 rather than 12.04.

[jardag]

I solved this by using the linux default driver rtl8192ce and creating file
/etc/modprobe.d/rtl8192ce.conf
like this:

jardag@precise-HP:/etc/modprobe.d$ cat rtl8192ce.conf
options rtl8192ce ips=0 fwlps=0 debug=2

some guys also put in "swenc=1" but i did not need it.
