i have issues with the WLAN internet speed of my L7310W notebook.
As far as i already learned the internal Atheros AR5005G network adaptor is slow as hell and will not go beyond 5.000 kbit/s
So i plugged in a USB adaptor with the REALTEK RTL 8187L chipset.
That stick works fine on various other PCs and gives me the full 16.000 kbit/s of my line.
But not on the L7310W notebook.
Here the speed is as low as the speed of the internal adaptor and will also not go beyond 5.000 kbit/s
What i have done so far is that i optimized the network settings with the "DFÜ-Speed" software and also made sure that the REALTEK driver is uptodate.
I also make sure that the notebook is really connected via the USB-stick and not accidentally via the the internal network adaptor.
Also i want to mention that the speed is very good (16.000 kbit/s) when the notebook is connected via LAN-cable to the modem.
Can anybody tell me what is going wrong and what else i can do to get more speed out of the USB WLAN adaptor?
Many thanks in advance

PS: deactivating the internal ATHEROS adaptor does not affect the WLAN speed of the USB adaptor.
PPS: OS is "XP Home Edition SP3"
EDIT: updating to the newest VIA PN800 + VT8235CE drivers solved the problem.
