xFI is not getting full speed in bridge mode

Hi everyone,

 

I just upgraded my internet to Gigabit and I had to use xFi modem/router as a part of the deal. I have my own edgerouter and I would like to use it. Therefore, I had to turn on brigde mode on the xFI but then I was getting only 200Mbps max. When bridge mode is off, I could get full speed. Anyone has similar issue? 

 

I hate using xFi as a router since I don't have full control of my home network and it lacks of advance features. 

 

Thanks,

Re: xFI is not getting full speed in bridge mode

Just look around the forums and you'll see that there are boatloads of issues with gateway devices !!

There is always an inherent disadvantage with these. Combo gateway devices are always a compromise in both quality and performance compared to separate units. Also, only the ISP can update the firmware so you are always a prisoner of that / them. And the firmware is typically crippled by the ISP's customizing of it and they typically eliminate valuable features.

One of the biggest issues with them is that it is far more difficult to diagnose connectivity issues when it comes to troubleshooting. You can't narrow things down by using the process of elimination by removing just the router from the path. And if either segment fails / malfunctions, you have a total failure. 

Get separate units and keep the control of your home network in your hands instead of theirs, you'll be much happier !

Thanks for your response. I agree with you 100%. If I don't use their modem/router, I have to pay $50 extra and that's too much. I have my own modem and router that can do way better than their xFi.

Which model Edgerouter do you have? I seem to recall issues with the Edgerouter-X when QoS is enabled or hardware offloading is disabled.

Re: xFI is not getting full speed in bridge mode

I just tried enabling HW offloading but no luck. Do you get full speed when xFi is in bridge mode?
I was getting 1 gigabit speed with my Edgerouter while using my own modem Arris 8200. I wish I could get rid of this xFi device and not having to pay $50 extra

Did you remember to reboot the ER-L? 

 

I've never had any issues with device throroughput, either with the XB6, the SB8200, or my current CM1150V. They've all hit ~940 Mbps over Ethernet.

my XB6 while in router mode can hit full speed. But I don't want to use it as a router because of its limitations. Did you use your XB6 in bridge mode and getting full speed with your own router?

Yep, with an Airport Extreme 6th Gen, and an ASUS RT-AC68P.

Re: xFI is not getting full speed in bridge mode

The issue has been resolved. I did the following not sure which one fixed the issue

 

Enable ipv6 offload

Disable net flow

 

ubnt@ubnt:~$ show ubnt offload

IP offload module : loaded
IPv4
forwarding: enabled
vlan : enabled
pppoe : enabled
gre : enabled
IPv6
forwarding: enabled
vlan : disabled
pppoe : enabled

IPSec offload module: loaded

Traffic Analysis :
export : disabled
dpi : disabled
version : 1.422

 

Now I can get full speed with xFI in bridge mode and my Endgerouter lite
