After much thought I’ve gone for an Asus RT-AC66U, which supports “up to” 450Mbps on 2.4 GHz and 1.3Gbps on 5 GHz. It isn’t cheap, but it isn’t silly money either and should do me until gigabit speeds becomes obsolete. I’m not even sure if any of my laptops support that speed. Well, almost certainly not AC, but possibly N. The old saying “buy cheap, buy twice” was in my mind going through this. As such I was hesitant to look at TP-link and other even lesser known brands which were about the only really cheap options. Although Asus aren’t a networking brand, these routers review well all round.
I also considered the slower Asus which was priced and spec’d about the same as the Netgear I was looking at previously, but both only had internal antennas so I couldn’t be sure how advanced its capabilities were. There’s also a model slightly above the one I got, which supports slightly fast N speeds on 2.4 GHz, but I decided this wasn’t worth it since I’m looking to get off 2.4 GHz anyway.
Oh, I figured out why I had such difficulty locating APs earlier. It seems quite simply they’re not commonly made any more. There’s a large amount more choice looking for wireless routers.
