Verizon Fios + Wireless Repeater/Range Extender -Please Help

I've been doing research on some moderately priced wireless repeaters, but it seems they don't work unless you have the same brand as the original AP. Seeing as I have a Verizon Fios router connected to the main computer in my house I'm wondering if I'm going to have a problem setting up stand-alone repeater in another location.

Could anyone with experience please recommend a repeater that should work fine, or at least give me some tips to send me in the right direction, as I'm kind of in a time-crunch right now, and don't want to rush into something that's just a headache.

I was looking at the LINKSYS WAP54G originally

I appreciate any help.

I'd like to do this in the most cost-efficient way possible, and buying another AP just to plug into the original router seems like a major waste. It's a decent router to begin with.

And no, I can't find any vendor info on the Verizon router, looks custom.

I'm sure there has to be a Fios customer out there with experience here. Verizon customer service even told me to use a repeater, but couldn't tell me which model to use, specifically.

I was in the same boat.

I did the following.

I disabled the wireless in the FIOS router.
I purchased a Linksys SRX 400 (MIMO router, the N routers weren't out yet).
I also purchased a linksys srx4 card.

I disable dhcp on the linksys, and just use it as a switch, and for wireless.

I now get great connection throughout the house. The laptop wireless client says
something ridiculous like 270Mbs on the connection, but I don't believe it.
But my connection now works through the entire house without any problems.
My other laptop with a 802.11 G card works fine, and says 35-54 at all times.

Just a suggestion, as you may be able to get a deal on a wireless N router, and have that work through your entire house, without having to mess with the access points.

You can also use powerlines.
