With a WSL button on the router installation will go well, unfortunately, my A1 router has no such button (Pirelli). Thus began the problems, and I had to contact the service. Nice staff who has tried together in 2 hours with me everything. At the end was nothing more, no longer my WLAN - despite the outrageously expensive international call! Three more calls to the A1 service brought least the router function again, I advise all who have similar routers, from buying from. Addendum 04.13.2015: CSL was very accommodating even after returning, and sent me a two-antenna wireless dongle. So I have the desired range. The service of CSL is really fantastic!
