I currently have a Linksys WAG 160N, one of the earlier models, which is driving me a bit mad. The DHCP has the annoying feature of allocating addresses in the wrong range, which I think is a known issue with this router, and now randomly disconnects requiring a reset, so I've decided to upgrade. We're on O2, via LLU, and have a lot of devices connected wirelessly, laptop, MAC book, IPAD, various mobile phones, Xbox etc etc, also have quite a large house, where the signal drops quite low upstairs.
Looking around PC world today (don't worry don't plan on buying from there), Everything seems aimed at small/medium house, medium usage. What are the best ADSL routers for heavy usage, quite large houses? Or should I be looking at a business type router instead?
