LB1120 Bridge Mode - No Connectivity
Hello, Trying out an LB1120 before installing across three locations as failover devices. Using AT&T and testing behind a consumer Linksys E2500 with default settings. The LB1120 works fine using...
A new firmware has been posted on the update servers that fixes the LB bridge mode issue. To update LB1120, LB1121 or LB2120 to latest Firmware log into the LB web ui and go to Settings àGeneral à Software and Reset once there select check for update and wait then simply follow onscreen instructions to update the Firmware. See below for example of how the LB2120 Firmware Info screen looks like after update. For other device just need to make sure that you are using App Version: NTG9X07C_12.09.05.27
After being in contact with support for over a month with nearly 20 back and forth exchanges they sent me a message this morning telling me they have no fix.
This was after numerous contacts telling me they duplicated the problem and had a firmware fix for it. Over the next three weeks several more contacts were made inquiring on when the fix was going available. They told me to update the firmware and the new version would be installed. When that didn't happen its like support returned to the top of the diagnostic menu tree repeating everything over again.
As of now it has been a total waste of time and they appear to be washing their hands of the situation. I will keep my ticket open as long as I can but I suspect they are done with support.
Netgear has had the beta FW to fix the LB bridge issues for sometime now so official FW to fix the problem should be availble sometime in the near future. For those of you having issues with LB bridge mode where your router is not able to work with subnet mask 255.255.255.255 that LB uses in bridge mode you need to reach out to DarrenM and provide him with your contact info and your LB model SN and IMEI and Netgear can push the beta fw with fix to your device.
For those of you who have reached out to Netgear and got the beta FW to fix the issue you need to make sure you see the following version numbers:
Firmware Version: M18Q2_v12.09.163431
Firmware Build Date: Unknown
App Version: NTG9X07C_12.09.05.26
Web App Version: LBHDATA_03.03.103.165
Bootloader Version: Bootloader Ver: v1.0.0
Hardware Version: 08
If your device has the same version then you are on the beta FW already and if the problem still persist I would reachout to you router vendors and get the latest FW verison for your router. Most new routers should not have an issue with a connection such as one provided with LB in bridge mode where subnet mask is 255.255.255.255. The reason LB utilzes this subnetmask in bridge mode is becuse a network with a subnet mask of 255.255.255.255 puts each device inside its own subnet, forcing them to communicate with the router before communicating with any other device.
As always if any other issue occur partining to bridge mode after beta FW is applied your best bet is to reach out to the Netgear support team and work with them to get to the bottom of the problem.
Hi Ernest,
Although a /32 (hostroute) mask is valid, I find many if not most modern routers and firewalls do not properly support it. Given that, it is best to avoid using it and saving everyone a lot of grief.
I think part of the problem and that the general rule we use is that the default gateway needs to be on the same subnet as the interface. Using a /32 breaks that logical rule.
I have been using the beta firmware for a while and it has been working fine with both SonicWALL and Cisco firewalls.
GaryEinstein I totally agree with you that the best practice is to avoid using it and follow the general rule where the default gateway needs to be on the same subnet as the interface. Hopefully this a lesson learned for Netgear Aircard firmware team.
Hi Erenst
I did send your suggestions to Darren en Support. Today I was able to upgrade my LB2120 to the new version. Tested it and it works in birdge mode to a DD-WRT (linksys e1000). Thanks all to make it happen...

The Firmware is coming for Europe in the coming weeks that has a fix for this.
