I accidentaly purchased a D-Link with an internal antenna. That sucked.
I had a Linksys WAG325N that did the job, but the modem inside dosn't work anymore.
The most recent wireless router I purchased today was a 288 dollar Belkin Wireless N Modem Router with 2 external antennas.
I don't want to buy another WAG325N, because of the modem problem. I think the only reason it did any good with our increadably thick walls and roof is because it has 2 antenna on each side of what looks like a directional antenna in the middle.
I need excelent range and penetration. A router with directional antenna would be the best with an ADSL 2+ capable modem.
I want to avoid buying a modem and access point seperatly. But will as a last resort.
The budget ends at about 400 dollars.
