Very slow Wifi Speed - how to fix?

English Network/Internet
#1

Unfortunately I have very slow WLAN speed. Not complaining about 25 or 50 Mbit, but I have just kbits! Youtube is rarely usable… :frowning:
See here, first three is with WLAN, latter two is wired:

From my smartphone I get same results as wired. So its not about wireless router, nor internet speed.

Anything I can do about this?[/size]

Hello there,

Can you provide us more details on this?

Is this a fresh system install?
Did this wireless card ever worked well before (with other systems and/or other circumstances)?
Did you start perceiving the slow throughput after any change on the system or on the router? If yes, which change?

#3

It is a fresh install.
Didn’t test this card before / at all. (I can try a live environment, if you can suggest one)
It was from the beginning, no changes on the router.

Sadly, if you do a quick search online using ‘rt2500pci slow’ and similar, you’ll get a large number of hits describing the same issue. Most are old reports, but it doesn’t seem to have ever been resolved. For example…

A commonly suggested ‘workaround’ seems to have been to lock the modulation rate using something like

sudo iwconfig wlan0 rate 11M

but YMMV with this.

My advice would be to take the pragmatic approach and replace your wireless hardware with something more reliable.

#5

Ok, thanks.

Unfortunately that workaround doesn’t work here.

Yeah, but how to find out in advance? I mean after all, if you look for that chipset it is listed as supported… :-/

Yup, and adding my experience with this chipset, it is well supported crap
hardware (not only under linux).
