I experience relatively slow download speed on my laptop while everything is OK on my PC.
The configuration: compaq nx 9030, 1 GB RAM, Intel Pro/Wireless 2200BG, WinXP SP2, NOD32, 8 mbit/512 kbit internet at TVNet Hungary.
I measure steady 2.4 mbit download speed at both ftp.tvnet.hu
and speedtest.net while the upload speed is almost maximal. I've made several attempts to find the reason of the not optimal download speed:
- connecting directly through the modem without using the router
- running a scan by Ad-Aware
- checking running processes and services manually for suspicious items
- checking available wireless bandwidth by copying files between the computers (~18 mbit/s)
On the PC that is connected to the same router I measured 6-7 mbit/s down and 500 kb/s up.
What may be misconfigured? Are there programs that limit download speed invisibly? I use NetLimiter 1.30 and Ethereal but they weren't running during the tests.
