I have a RB750Gr3 with 2 wAP in CAPsMAN configuration. I have gigabit internet coming into my house with the AT&T router setup to do DMZ mode to the RB750. I have Ethernet 1 as the WAN port and then Ethernet 2-5 and CAPS 1-4 setup on a Bridge (none of them are setup as slaves in switch). My ‘speedtest’ cap out around 170MB down and 150MB up. If I bypass the RB750 and just hook my PC into the AT&T router in DMZ mode I easily pull 900MB down and 900MB up. I have disabled all firewall rules and the performance does not change. I am not using an VPN or VLAN configuration. Performance is similar on the AC wireless as well. What can I provide to help figure this out.
As a side note: using DMZ is far from optimal, you’d better put the AT&T router in bridge mode, and setup the RB750Gr3 so that it takes the public ip, i.e. ATT will be a mere modem.
Your AT&T “router” is probably not that good other than for simple stuff. Doing DMZ might hit it’s CPU pretty hard. If it can work as a bridge (modem) between your physical connection and ethernet you have a much better setup. AT&T should be able to point you to information to do this. Their DSL routers can do it. Or just buy a reputable and compatible modem.
ATT U-Verse doesn’t support bridge mode and unaware of any 3rd party modem support.
It’s the primary reason I don’t even consider their residential Internet when I talk with people about Internet options. If an ISP can’t offer me layer 3 with either PPP or Ethernet at layer 2 they simply won’t be considered as a valid solution.
I upgraded to the latest 6.41rc11 beta which changed the way bridge/switch mode works and now I avg about 380 down/up. Again if I bypass the MikroTik and just DMZ my desktop I get 900/900. If i replace the mikrotik with an old linksys router with AT&T device in DMZ mode I get 900/900. I am fairly certain this is a mikrotik config issue.
When you mentioned an export – what would I need to do to do that?
