300 mbps fiber internet upgraded from 100 mbps

I recently upgraded my AT&T Internet service to 300 Mbps, up from 100 Mbps, but my download speed using AT&T speed test website never goes above about 95 Mbps, the exact same as before the upgrade. AT&T has verified that I have 300 Mbps fiber service to my home. My AT&T Pace modem/router of RJ45 ethernet jacks shows 3 computers connected with a 1000 Mbps connection (orange light) and one OOMA internet phone device connected at 100 Mbps (green light), which is correct because all my computers have Gigabit ethernet and the OOMA box only has 100 Mbps Ethernet. Any connection that I make from computer to computer through the Pace router (all using Windows 10 Prof) shows 1000 Mbps (1 Gbps connection). But going out to the Internet I only get slightly below 100 Mbps.

AT&T sent me a new Pace router/modem, and after I installed it, that made no difference.

In looking at the RJ45 cat 5e plug that goes into my home and is connected to the ONT jack on the Pace modem/router (I have fiber to my home that is converted to the ONT cat 5e cable), I notice that the RJ45 plug wires look different than I am used to (I normally create my own cat 5e cables with a crimp tool, etc so I am familiar with them). On the cat 5e going to the ONT plug on the Pace modem/router, there are the two rows of wires, one being the solid colors, and another row with the striped wires. I am wondering if only the solid color wires are connected, which would account for the maximum 100 Mbps connection into my Pace modem/router. It is hard to tell if the second row of striped wires are also connected to the gold contacts of the plug.

In the pic below, the solid color wires are on the right, and barely visible on the left is the row of striped color wires. I can't tell if they are actually connected to the outer gold contacts. Has anyone ever seen an RJ45 plug with this kind of dual row configuration where all 8 wires are actually connected?

I have heard of instances where AT&T only used 4 of the wires during initial installation, instead of all 8 wires, back when customers did not have more than 100 Mbps service.

AT&T finally came to my home and fixed the problem. It took a long time because they kept trying to "fix" the problem remotely. After the technician arrived, he confirmed that the AT&T supplied Cat 5e cable to the ONT on my PACE modem only had 4 hot wires, which means the ethernet limit is 100 Mbps.

They also confirmed that I did not have fiber to the inside of my home, as the box to convert fiber to ethernet was outside. What confused me was that there a box inside my home (besides the modem/router) but that was only supplying power to the outside box.

AT&T completely rewired my fiber connection and the fiber cable now goes directly from outside my home to the inside of my home and connected directly to a NBS AT&T BGW-320 modem/router (with WiFi, etc) with Integrated/Built-in ONT, instead of having a separate box to convert fiber to ethernet and then going to the PACE modem.

My Internet speed is now 300 Mbps as promised.

Next time, when someone says they make their own ethernet cables (and is therefore fairly knowledgeable about networking), and the AT&T supplied ethernet cable only had 4 of the 8 wires properly crimped to the RJ-45 plug  (and provides a photo to prove it), you should listen to the customer instead of treating them like an (Edited per community guidelines).

Try a different Ethernet cable. Have you used the gateway speedtest to see if you get 300 up and down?

The Ethernet cable from the ONT to the gateway cannot be changed?

login to the gateway. 

http://192.168.1.254/cgi-bin/broadbandstatistics.ha

diagnostics tab, speedtest. It might be under the device tab as well. Or use the the smart home app to run the speedtest. 

Test is from the gateway to the att network.

The speed test says 99.993 Mbps.

AT&T has assured me that on their end, it shows I have 300 Mbps service, and in fact they previously sent me a letter saying they automatically upgraded everyone in my area who had 100 Mbps fiber to 300 Mbps at no additional cost.

Under the LAN tab, Wired Interfaces, it shows that my 3 computers are connected to the Pace router with a 1 Gbps connection, and my OOMA box connected with a 100 Mbps connection, just as I previously explained according to the LED colors on the Pace Ethernet sockets.

The Cat 5e Ethernet cable that is plugged into the ONT socket in the Pace Modem/Router on one end, then goes into a a hole in an outside wall of my home on the second story, and then to some other AT&T fiber box. It is not my Ethernet cable, and even if I could open the AT&T fiber box on the outside of my home, I would not attempt to do that since it belongs to AT&T and it is their responsibility, and I am quite sure they don't want me messing with that fiber box equipment. Also, I am not personally going to be replacing an Ethernet cable that high (2nd story) and that long on the outside of my house.

My original question was about whether AT&T wired the Cat 5e Ethernet connector to use all 8 wires in order to achieve speeds higher than 100 Mbps, based on the photo I supplied. If it is not wired correctly, it is AT&T's responsibility to fix it. If I was certain that the problem was only on the end that plugs into the Pace Modem/Router ONT socket, I would rewire the RJ45 connector myself (I have crimp tool and make my own Ethernet cables), but I suspect that if it is wired wrong on one end, it is wired wrong on both ends, and as explained above I don't have access to the other end of that particular cable (obviously AT&T does have access to it).

Sounds like you may have an outdoor ONT. Call for a tech visit to check your wiring. Say you are not getting the paid for speeds on your devices. You are checking with a wired device, correct? 

You don’t have an ONT like this inside your home?

All my computers are wired via Cat 5e Ethernet that have 1 Gbps connection to the router. Not using WiFi on those devices. I made that explicitly clear.

I actually do have a some kind of box inside my home, but not the same one as in your pic. But I think they buried the connection between the Fiber box and the Cat 5e cable inside my wall, and I cannot see to how to replace the Ethernet cable. I don't want to mess with it, and I don't think AT&T wants me to mess with it either. If the Cat 5e plug that goes into my Pace modem/router only has 4 wires connected (2 pairs), that is all I want to know in order to get AT&T to fix it.

As I said, call for a tech visit. Let att check and fix it. Post a picture of what you have inside the house.

I don’t recall anyone here calling you an (Edited per community guidelines). This is a customer to customer that provides help to fellow customers. I’m glad you took my advice to get a tech visit. Sounds like you have your internet service wired to the current standard.
