I have a TrendNet 658BRM that's giving me endless issues. I'm using an old trusty Tenda router for the time being while I look around for a suitable replacement router. So without repeating the mistake of the TrendNet again, which N300 routers should I look preferably under R1000? TP-Link, Netgear, Billion or Tenda? I would like to get the Asus DSLN12U B1 but I doubt that's available locally. All advice would be highly appreciated
