I used to have an old wifi but it's that old the software I used to use to set it up doesn't even run under 7. This isn't really my problem though since I was pretty sure I'd have to update anyway. It's unlikely it would be able to repeat a signal from an N router let alone use anything better then WEP.
Anyway. I was looking for suggestions on getting a good repeater. I saw this one: Best Wireless Repeater | Wifi Repeaters Boosters and Range Extenders
which looks pretty good. I've never used anything from Amped before though so I'm kind of tempted to go for a Netgear or something instead.
I was also considering buying a router and setting DD-WRT up but I don't know how they compare?
Cheers for any advice.
