My desktop computer is getting terrible download speeds, while other devices work just fine on the same network. Here are speedtest.net results from my devices, Mbps:
- Nexus 4: 24.9 down / 26.8 up
- MacBook: 31.3 down / 28.5 up
- Desktop: 6.6 down / 28.2 up
All three devices connect to the same network (also tested in the same physical location), hitting the same remote server. Results stay fairly consistent between runs.
The desktop PC uses a TP Link TL-WN881ND PCI-e wifi card and runs Windows 8 (identifies as 'Qualcomm Atheros AR9287 Wireless Network Adapter'), default drivers, no additional wifi-related software installed.
My router is a TP Link TL-WR841N, default firmware. I have tried disabling WMM, changing router mode / channel width - none of those improved download speeds on the desktop.
Also, tried using my phone as a wifi hotspot and got the following results:
- MacBook: 10.0 down / 1.6 up
- Desktop: 9.0 down / 1.6 up
Much closer this time - problems with the specific wifi card / router combination?
Edit: I 'fixed' my issue by switching WiFi card to a TP Link TL-WDN4800. However, I still do not know what caused the original problem.

If you hard wire the desktop, does the download speed change? – Dave – 2013-08-21T07:34:41.820
Unfortunately I can't run cables to the desktop. It does go up when connected to another wifi (phone in hotspot mode), but that goes through another provider. – Toms Mikoss – 2013-08-21T07:46:52.237
Are you able to test a 'dongle' or a different wifi card? – Dave – 2013-08-21T07:54:44.547
Yes, that seemed to fix the issue, whatever it was. – Toms Mikoss – 2013-08-22T10:27:38.153
