Internet routers x3 (Swanwick DE55)

I have 3 unwanted internet routers I appear to have collected down the years. Probably not of much use as routers but can easily be re-purposed as a wi-fi extender (plenty of How To guides on the internet). Complete with power supplies, though none of them have seen any power for a few years and are therefore untested. See images for model/part numbers.
