Need help ASAP please

Message 1 of 2

So I just got Fios and got the gigabyte speeds. Since techs aren’t allowed in my home I did self install. After installing the G3100 router I noticed horrible WiFi speeds. Only 30down and 40up. I disabled the SON feature as some had suggested but I would only get 60 download on the 5g band. I checked a wired connection and noticed I was only getting 90 download. I called tech support and they said it is reading fine on their end and that it is my device. So I decided to troubleshoot the problem myself as I know it’s not my devices. The first thing I did was purchase a new CAT6 cable and ran it from the ONT box to the router. 45.00 later I was good. I was getting 560down and 480 up over WiFi. Direct connected I was 970down and 880 up. I was happy. Than I woke the next morning to the slow WiFi. I checked the wired connection and sure enough it’s slow. I than decided to go into the routers interface and take a look around. I found the problem. The issue is in the settings tab under port configuration. The WAN port was set to auto and was only allowing 100mbps full duplex. I manually switched this to 1000mbps full and I’m all good again. The next morning it’s back to 100. So I call tech support again and they believe it to be the cable even though I explained I replaced the cable as it was my first thought too. They had me do a factory reset on the router and told me not to change anything and see if it defaults back to 100. Not 2min after I hung up it was back to 100. Now I can’t even manually change it to 1000 because if I do it says wan is disconnected and I have no internet.  I don’t know what to do. Do I spend another 40.00 on another cable and run it again. With my ONT outside this was a pain in my butt the first time and I hate throwing money away. Could this be something else?  Any help would be greatly appreciated. Thank you!

If the ethernet cable has been replaced then the issue could be with the G3100. I would call and have them ship you a replacement. If that still doesn't work then it could be the ONT. Luckily your ONT is outside and can be easily replaced by a technician.
