I think that it is not more on the shops’ shelves, but just in case: do not buy a WAG54G from Linksys. It is a router with ADSL model and wifi, and from the beginning it has just given me problems. Random hangs, poor wireless performance, and the ethernet part is broken and now only works at 10 Mbps. In conclusion, it’s a great shit. And AFAIK, I’m not the only one experiencing these problems.
Linksys has some good products, even some routers and APs can be hacked to install Linux on it, but the WAG54G was a big mistake that has produced a very bad impression on lots of customers.
