Description:

It seems that my issues with this driver never end. For some time I've been having this strange problem where my bandwidth seems to be suddenly capped below 1M (I have 6M) after a while. Restarting the network connection fixes it, but I usually have to do so many times every hour.

Additional info:

From lsusb, adapter is "050d:945a Belkin Components F7D1101 v1 Basic Wireless Adapter [Realtek RTL8188SU]".
Other computers in the house don't have this problem, and I also don't recall having any issues when I ran Windows here.
Wireless network uses WEP.

Steps to reproduce:

- Connect adapter.
- Do a speed test, it should work well and use all bandwidth.
- Repeat the process (multiple times if necessary), after a while, bandwidth should be capped to around 1M or 500k.
This task depends upon

Status on 3.10.x?

The cases of bandwidth capping have decreased in frequency with each update from 3.10 onwards, on 3.10.3 I can recall it happening just once or twice.

Now at 3.10.4 everything seems to be fine, so I guess this can be closed now.

Sorry for the late response, I don't check my mail very often.

It started happened again on 3.10.5.

This is annoying as hell, really.

Status on 3.11.1?

I haven't been on my home computer for a while lately, but I can tell on 3.11 and 3.11.1 (just updated last night) the problems seem to be gone *for now*.

(on 3.10.11 it still happened every once in a while)

The biggest problem with trying to study this behavior is that it's completely unpredictable, maybe it's fine now but right after I post this comment it will drop again. :S

I've been considering this could be just a hardware problem, the adapter overheating or something, although sometimes it's not really hot when it happens.

Blegh, it happened again right now :(

I close this i cannot fix anything, you might consider reporting it to upstream developers.
