Wireless/Wired Issue

[TimMB]

Hello chaps/chappets

I know there are some IT buffs here, so I'd thought I'd put my problem to you.

Basically I have 3 PCs running Windows Vista (Ultimate/Ultimate and Basic)

They are all connected to each other via a wireless router one of which is wired and the other two wirelessly.

The router is an Belkin N1 Vision, the two wireless machines have N wireless adapters and obviously the other is wired straight into the router via 1 Gigabit Ethernet.

When transferring files from "wireless to wired" from either wireless machines I get around 8-10 MB/s (megabytes/sec). As soon as I transfer wireless to wireless I get 1.5MB/s.

Now it can't surely be anything to do with limitations of wireless as I am getting 8-10MB/s from wireless to wired.

Really baffling me, any insight would be much appreciated.

Edit: All drivers are up-to-date.

wireless N only works at about 40% in good conditions and the speed is measured in bits so with overheads in the packets and encryption 1.5MB is quite good.

When transferring wireless to wireless your halfing the capacity. Wired to wireless your getting full capacity.

Although that does seem particularly slow. It probably just a shitty Belkin router (I've never actually seen a good piece of Belkin kit)
