I currently use a dongle in my laptop but I've been having problems with it connecting at times and i went into 3 offline (three being my provider) and I read that I could get a router and plug the dongle into which three computers can work off. I dont know what router I'm looking for in ebay, also if i get this router can I use tablets then too. I'm not clued up in techno.... Please help me!!!!Would be much appreciated. Thanks
