Sorry for the long post!
Guys i tried to bridge this with my
Netgear X4S (
R7800) back when March when i changed to Airtel Fiber but nothing worked. I searched
google and used the alternate method of using DMZ and configuring both
routers. I posted the method earlier today on reddit as a solution for people like me as i saw some posts with similar issues. I have been using this for months and it is working perfectly. My pc is connected to my X4S using
Netgear A7000 wifi adapter and there are no speed or nat issues in online gaming either. All devices are connected through my X4S and have disabled radios of my Airtel. So sharing it here too if someone wants to try this method if bridge still doesn't work.
Coincidentally my telephone was not working today so Airtel support changed the modem and i now have the newer
Nokia G-2425G-A. One immediate change i noticed is now you can't change any settings on the Network-WAN page and nothing is editable unlike the G-140W-F. See the pics below:
G-140W-F
G-2425G-A
Anyway these settings do not matter in this method and already am using it on the new modem. I know its not as simple as bridge mode but what works for me and worth a try for those like me.
Settings for Airtel Nokia Modem+Router (
192.168.1.1 in my case). Both router should not be connected with each other when configuring either.
1 - LAN Settings: To get your other router working seamlessly first you need to know the
MAC address of the other router you are connecting to the airtel one. This is usually written itself on the router at the back. This is because you need to setup DMZ on your airtel router for your other router (step 2). For that you need to give that router a static ip from your airtel router. Use any one from its DHCP range (i set mine for
192.168.1.7 for example).
2 - DMZ: Enable DMZ as below after you have added a static entry for your other router.
3 - Finally
DNS, Firewall and UPnP settings need to be like this (if its not already)
Rest of the settings don't need to be touched. Now for your other router settings.
4 - Internet Setup (WAN): Since Airtel will be making internet connection you don't need to using your ISP login settings on your other router and let them remain on default. Here are mine on my Netgear for example:
5 - Lan Settings: My netgear auto-switched from
192.168.1.1 to
10.0.0.1 once it detected a conflict with airtel. You can use any ip adress you want like
192.168.2.1 or
192.168.0.1 etc
6 - Nat and UPnP: Nat should be disabled on this router as it creates a conflict with airtel where it is enabled
7 - Now with both routers configured connect them using ethernet cable. The cable should go into internet (coloured) port of your other router.
Hope this works for you if bridge mode is not working.
