Help

I am having the same issue. Several months ago I upgraded from 200 to 400. It immediately slowed to about 70-90 on both ethernet and wifi using two different PC's. Both windows 10. Before the upgrade, it was hot, getting way over 200. When I upgraded to 400 is when it slowed, and I mean it was immediate. I tried everything I saw on these forums and many others.

The next day it magically started working and I got 475 or so.

I have not changed anything hardware or software related since.

I just upgraded to 800 yesterday and the same [Edited: "Language"] thing happened. I'm not doing anything this time. I called and they pushed the code or something to the router. Said they have something on their end that shows red on their lines. They said that last time too. There is something on Xfinity's side that is causing this issue. Not sure what it is.

I have the top tier modem from them, the white one. I have ethernet plugged into the orange labeled port that is capable of providing up to 2000mbps...

I just want what I'm paying for. If I'm upgrading and it takes a while for something to sync, fine, but don't slow my services down to 75-90 mbps!!!!

Edited: IT STILL ISN'T WORKING! ONLY GETTING 70-90 MBPS....

Hello @user_69266e and thank you for taking the time to connect with us here on the Xfinity Support Forums. I'm sorry to hear the services are not performing as they should, it sounds like you've already done a fair bit of troubleshooting with your devices. Whenever an upgrade takes place, the modem does restart to accept the new bootfile, which tells the modem what services it should be pushing out. Based on your description, you have one of our xFi Gateway 3rd Generation devices, as described below:


Our xFi Gateway 3rd Generation offers a new colorway (white/gray) to compliment your home decor, a less disruptive LED light, the fastest speeds, more ports, the widest coverage, exclusive WiFi management tools, Parental Controls and xFi Pods for extended coverage.

If there is a signal issue at the property, we can happily schedule someone to investigate and offer a fix. Have you had a repair technician out by chance?

So it takes multiple days for a boot file to be pushed and accepted by your device? Unacceptable, and so was the expert/official response.

Further more on this. I had a tech come out yesterday. He said he had to replace the modem/router. We changed it and still had the same issue. It slowly resolved itself somewhat finally though.

The problem I have now is that the laptop in the office is only getting 370-420 mbps download. That's what it was getting on the 400 plan I was on.... No improvement, and again unacceptable.

The ethernet on other hand is screaming fast. I can now die faster in Warzone and COD MP.... :)

Keep in mind everyone. All of these problems were on the Windows 10, both pro and home edition, PC's. The iphones were getting upwards of 500+ the whole time. 

It really seems like this is an issue between that OS and your equipment. I would suggest tracking it somehow.

I apologize if my wording was not clear in my original statement, a bootfile change should only take a few minutes, not several days, as you had stated in your original post. If for whatever reason it did take longer for a change to go through, this would indicate either a system issue of some kind, or a device incompatibility. In this instance, as it took several days for the speeds to come through, my intention was that there appeared to have been an error of some kind--whether the services did not finalize in the back-end same day and push the update through, or the modem was not reading the update in a timely manner.

 

Speeds over wireless are going to vary based on a number of factors, including number of devices on a network, device compatibility, construction of the home, etc. We would suggest confirming the laptop has the most up to date firmware for it's network driver and confirming that the network card is capable of achieving speeds higher than the ones posted. As the devices over Ethernet are achieving forecasted speeds, and the iPhones are achieving higher speeds, this indicates there may be something amiss with the other devices or they are unable of achieving those higher speeds over wireless. 

 

We have a device speeds website available, which has expected Wi-Fi speed under good conditions with a compatible service plan and router for consumer devices if needed. https://comca.st/2Z3lzIL
