Having problem connecting to certain services through router with new internet connection

[TRazerK]

I changed my ISP today from AmberIT to MyInternet due to AmberIT stopping their service in my area (Niketon) after this month. I've always used a standard Tenda router to connect to my PC through ethernet and also Wifi to my phone, been like this nearly 4 years without any issues

With the new connection however, everything is fine when connecting my PC directly to the ONU device provided by the ISP (without connecting thru my router). But when I connect through my router, I can't access certain things like....

1. speedtest.net site
2. fast.com site
3. Elite Dangerous game server (can't login)
4. AC: Origins (can't login)
5. Battlefield 1 -- I can connect and go into game, but the pings don't show up against each server

Haven't tested any other games or sites, but not sure what else I can't connect to. As I said, if I connect without router, then I can access all of these things just fine without any issues

1 thing to note is that MyInternet provides their connection through PPoE (they provided me a username and password to use the connection), whereas AmberIT uses DHCP

The culprit is obviously my router, but I fiddled through all the router settings in 192.168.0.1 and just could not find the setting that I need to change to make things work again. If anyone knows what to do or any solution, then please let me know. Thanks

Did they configure the connection hooked to the PC or router?

If the former then hook it to the router and call them to record a new MAC address.

I asked my ISP last about this if I can change the cable between the PC and the router whenever I want. They said no and told me to do this. They also use PPoE.

^If the MAC address was bound to the PC then he wouldn't have internet at all when using his router.

Try setting a static IP (local) for your PC, then enter that IP into the DMZ section of the router.

Does not work. Refuses to connect at all whenever setting a static local IP for PC. Router IP is 192.168.0.1 and I tried several addresses ie 192.168.0.10/20/30 but no luck. Am I missing something?

You should have the router assign the same IP to your PC, not insert an IP in LAN settings. But if you did do the latter, add 192.168.0.1 as the gateway and you should have internet.

Make sure you do the DMZ bit on the router.

Did both. If I assign static IP and gateway from PC settings, then I get a connection (windows says connected) but I can't connect to anything. And if I have the router assign IP to PC and setup DMZ host, I get the same partial connection where it refuses to connect to the sites as mentioned in my OP. Here's what I did on the router settings FYI...

Strange, you should at least have internet. Did you restart your router after assigning DMZ?

I do get internet if I assign IP from router to PC, but it's just the same situation as before where it doesn't connect to the games and sites I mentioned. Yup, restarted everything after setting IP/DMZ, still no luck. I will be calling up the ISP support tomorrow to see if they actually have to do something from their end but I highly doubt that's the case

Get a router from a friend and see if the same problem arises

Could you show the wan status page from the router?

Ok. I believe I have finally managed to solve this weird issue by myself thanks to more googling. As suggested in the last comment in this forum post, I lowered the MTU value from the default 1492 to 1450 in my router settings and WALLAHHH! Everything's all good now! Both speedtest sites check out, and can access all games no problem. How or why this worked though, I do not know yet

I never would've guessed that's the fix...TIL
