MBR1000 causing uplink jitter

Howdy

I realize this is not (exactly) EVDO related ... but I did buy my MBR1000 from 3GStore and am still using a 3G card as backup so . . .

We just installed WISP access at our house because the 3G downlink gets saturated at night and uplink stinks. Thinking of going with VOIP instead of a landline (WISP doesn't prohibit but doesn't provide any support).

Before committing, I've been doing some testing (using MYCONNECTION) which repeatedly showed HORRIBLE jitter on the uplink but very low jitter on the downlink. Was having a little buyers remorse on the WISP. Even fiddled around with the QOS settings in the Canopy Subscriber Module (SM) (the WISP left the default password set Shocked

) with no luck. Changed the SM from NAT to bridge and still poor performance.

Then on a whim, I hooked one of my laptops directly to the WAN port, reenabled NAT and DHCP on the SM and tried my tests. Low and behold - uplink jitter was actually BETTER than downlink.

So - it would appear that something on the MBR1000 is causing this. I've tried both ethernet and WIFI connections, DMZ, Traffic Shaping ON and OFF - even tried connecting the SM ethernet on the LAN side and just using the SM DHCP. It seems whatever traffic goes through the MBR1000 switch causes a lot of variability on the uplink side.

I've disconnected all other computers from the LAN side of the router.

I'm at a loss. Hate to give up on the router as the NAT functionality on the WISP SM is crappy and would rather just run it in bridge mode.

I know that Phone Power (a VOIP provider) recommends putting their ATA between the router and the WAN side of your ISP - but then it seems I'm defeating the purpose of having the MBR1000 doing the NAT and acting as my firewall (unless I don't understand how the ATA in bridge works).

Any thoughts around here before I take the plunge on VOIP?

Thanks,

Barry

did you try disabling the wiPipe tech?
