I POSTED THIS IN THE NETWORKING THREAD BUT RECEIVED NO REPLIES FOR 4 DAYS NOW. PLEASE IF SOMEONE ON THIS THREAD COULD HELP I WOULD REALLY APPRECIATE IT:

Hey all,

Hope someone can help me as I have been battling with this for a few months and I'm really at my wits end.

I have a iBurst Desktop modem, which connected to the WAN port of my IPLink router and all was working fine until one day, without any changes from my side, it stopped connecting to internet. I tried everything to get it back up but to no avail.

I subsequently put it down to a faulty WAN port on the router as the modem connected succesfully through USB and through a direct connection to my PC's LAN. For a few months I have been connecting it through USB and then sharing the connection through WiFi.

A Week ago I went out and bought a new router (Huawei HG532F) but I'm still having the same problem. No matter what I do, I can't get it connected through WAN (PPPoE) connection. Keeps telling me "No internet connection".

If I set up a PPPoE connection on Windows itself, it works (through USB as well as LAN), but can't get it to work on both routers.

Any help would be appreciated!

Regards,

Have you checked, are both USB modem and router compatible with each other?
Are they running the latest firmware on each device?
 
Also make sure of the MTU size, it differs for Iburst and you might have to change it on the router in order for it to work. The MTU size for iBurst should be around 1352 or 1395.

Do either of your routers show any logs of what is happening while trying to establish the PPPoE connection?

No, it should be 1392 exactly.

As stated, nothing changed on my side, everything was working and then it was not working anymore. Even if I can just get it to work again with the old router it would be fine.
