Wireless network. Ethernet slow.

Running Leap 42.1 with Plasma 5.4.3.

Connected to wireless network via PCI TL-WN350GS network card.

Wireless was working fine until I did a patch update yesterday after being prompted by the Software update manager.

I plugged in a network cable into the machine.

You can see how the response times change when I disable the wireless and the network cable takes over. So it’s obviously the problem is with the wireless config on the Leap box because the lappy is on the wireless as well and there is not problem.

If I switch back to wireless the speed is comparable to the eth0.

iwlist wlan0 bitrate
wlan0 unknown bit-rate information.
Current Bit Rate:54 Mb/s

Will keep an eye on this.

The problem is very similar to the one described in this thread: https://forums.opensuse.org/showthread.php/404349-Fast-Ethernet-but-slow-wireless[/size][/size][/size][/size][/size]

I have read similar accounts concerning this hardware, with hardware encryption being problematic and leading to symptoms as you’ve described, but don’t know if this is still applicable to recent driver versions. In any case, it might be worth disabling it (with nohwcrypt=1) see if it helps. Described here


Excellent post. That could be the problem. I will try the solution the next time the problem occurs.

By the way is there any way to mark these threads “solved” like on the Ubuntu forum?

No, we don’t do that here. You can post the resolution though, along with any other applicable comments. Let us know how you get on. :slight_smile:
