Right now I have a BT Voyager 2110 wireless router for the past 6 years or so. I recently bought a new Western Digital NAS but I'm only able to transfer data wirelessly at 2.5 MBps. If I physically plug into the router I get about 10 MBps, but that's still very slow, because I want to be transferring hundreds of gigabytes of data.
My wifi card is a Dell 1397 WLAN Mini-Card which appears (according to the device properties) to be 802.11h+d.
If I get a gigabit wireless router will this help? I don't want to spend more than 30 or 40 euro (or gbp or usd or whatever) on the device. At this price range could I expect to see a noticeable improvement?
