Title:
8086:4236 [Lenovo ThinkPad X200] Slow WiFi with Intel 5300 on N
networks
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I use Ubuntu 13.10 on a Thinkpad X200 (Intel Ultimate N WiFi Link 5300
WLAN).
What I expect to happen (what happened before):
- Connect to N network
- Do a speedest.net
- get ~32Mbps
What actually happens:
- With N network I get ~1Mbps
- Disabled wifi / speedtest via ethernet ~32Mbps / restarted modem and router
anyway, same results
What I do instead:
- I change my router settings to BG-mixed (for the same network)
- then I get ~8Mbps
Now, I was offered a few updates earlier today and didn't really look
at what was updated. However, this behaviour is new, it didn't happen
before and I think it might be due to some update regression.
