I used to get speeds near 100kb/s and now i get speeds of around 45 kb/s.
You are making us shoot into the dark. It would help to know at least:
#1 The brand and model of your modem.
#2 The brand and model of your router.
The brand of my modem is Westell and the model is 6100.
The brand of my router is D-Link and the model is WBR-1310.
What happens when you visit http://192.168.1.1/ ? Do you receive a Westell page or do you receive a D-Link login page?
I get my westell modem.
My internet speed is almost the same when I directly plug my computer to the modem.Transcever stats
