I have a 802.11 b/g wifi router that was provided by my ISP. The plan I subscribe to gives me about 650kB/s down. Which is fine... I understand you get what you pay for.
To this router, I had two computers connected by wifi. Both computers have 802.11 b/g/n cards. Internal network transfers between the two computers never go faster than about 300kB/s over wifi.
Thinking the router might be the issue, I connected one of the computers to it with a normal cable. I could then get internal network transfers of about 550kB/s. I can't wire the other computer because it's in a different room.
I called my ISP and asked if they'd replace my router with an 802.11n model. They said no because it's not defective.
So my question is: would obtaining an 802.11n router improve my internal transfer rate? If so, I can complain more forcefully, and/or purchase my own, which I would wire to the ISP's router and use to distribute the signal within my house.
