I'm looking for a router that is capable of working in a 10m radius through walls as well. Was thinking of the TP-Link MR3420. What would be the requirements for an AV router in terms of speed? Would like it to do DD-WRT or Open WRT, etc. I don't want it to be reset everyday, I just need something reliable. I don't have adsl just 3G. Can I get a second router if the signal is to weak to act as an extender? Looking for a router is worse than trying to find the perfect AV equipment.
