I’ve been having stable internet ever since I’ve gotten a Belkin n300 wireless USB adapter. However, after switching from Optus to Telstra internet, the download speeds dropped to below 0.5mbits/s from the usual 20-30mbit/s.
All my other devices are working fine and have no problems with download speed, except for my computer. I am wondering if I could change any adapter/router settings to fix the problem or if I should just buy a new adapter.
The router is a Netgear CG3100D-2BPAUS.
Edit: The problem seems to be coming from my pc. I've just swapped in an adapter from the fast desktop and the internet is still at the 0.5-2kbit/s range (the fast pc using the belkin adapter still has very fast internet). I am doing a virus scan to see if that is causing the problem but it might just be the router settings. Are there any settings that I can tweak?
