You can use rb951G and disable wireless if you don´t need them.
CPU allows overclock to 750Mhz
I did it with a gigabit pppoe connection. when it reaches 220Mbps it is rebooting. again and again and again
i switched it back to default frequency and it just stays at 220Mbps, without rebooting. PPPoE client with 1492MTU/MRU.
RouterOS v6.6
I will not mention the other router which is not offering vpn and other great features that Mikrotik does. I am tired of being banned (well, it happened once only,enough to know the age of one of the moderators)
951g-2hnd is a great router as long as you will use it with a static public ip and an atheros wireless client. i think it's the driver's fault for the atheros wireless chip. i will, again, not mention the other router with the same atheros wireless chip
