I had a Netgear Trek N300 travel router that I repurposed as a wifi access point. Looks like they're no longer made. Any wifi access point would work. Looking on Amazon Canada, this one looked OK. For more money, this one is even better, but probably overkill.Some good tips there.
What wifi bridge did you end up using? And what power line filter?
The power line filter is DIY and is described here.
