Hello, I've been using a Linksys WAG54GS router modem for the past few years, and now it's dying. Presently, I am using my ISP-supplied (TalkTalk) Huawei EchoLife H520b. Unfortunately, both of these don't have the best coverage out there, and with the HG520b, I am not getting any reception either upstairs or downstairs, relevant to where I put it. I prefer to have a Broadcom-based router, so I was wandering, what would you suggest I use for this? Thanks.
