Mine is working right now. Yes I changed my router, I was using the shaw provided Cisco router which combines the router and modem, but now I switched it back and returned to the old modem and I bought the Linksys E2500 then the wireless seems works very well now.
Do you know about the inssider software? It can check the channel overlapping in your community, which causes interference. If you don't here is the link: http://www.metageek.net/products/inssider/.
BTW, it is better if you can buy a router with dual band like linksys E2500, this router reduce the interference by providing both 2.4G and 5G bandwidth and our wireless card supports 5G.
