Slow WiFi after router upgrade

Slow WiFi after router upgrade

We recently were 'upgraded' to an Arris TG1682G Xfinity gateway for our home internet service.  We are on the 150/5 Performance Pro plan and were not having problems with our old router/gateway.  Since the 'upgrade' we have been having significant issues with speed.  I mostly observe this with our mobile devices.  Nothing is hard-wired into the equipment.  We have several home appliances (Roku, Xbox, etc.) as well as PCs using the WiFi without significant issue.  The major problem appears to be with phones.  Both iphones and Android devices are basically unusable on the new gateway.  Connecting doesn't seem to be a problem though I do note that I am reconnecting very often on my Samsung.  I have tried using network analyzer tools on my phone and have noticed that the signal is definitely weaker than the old gateway - even though it is placed in exactly the same location.  I really need to fix this issue or we will be canceling our service.  I have seen MANY other threads on the forums of similar experiences from other customers but no good solutions / findings.

Is it on the 2.4GHz, or just 5GHz, or both? Regardless of which one it is affecting, I will be posting some screenshots for you shortly to show you somethings to look for to see if you can get some improvement.

Also, are you using one SSID (names) or two different SSIDs? If one SSID, try disconnecting and reconnecting to the Wi-Fi. Also, is Ethernet ok?

  1. Log into your gateway at http://10.0.0.1 with the default username/password combo, if you have not changed it already of admin/password, if it is your first time logging into it, you will be forced to change your password first. (sorry about the blue coloring in that one)

3. Click Edit on the one for 2.4GHz

 4. I would at least change the channel bandwidth, that should be all you have to worry aboutScreen Shot 2018-08-09 at 12.49.52 PM.png2.4 Channel Bandwidth

 5. After those changes are saved, do the same thing to the 5GHz band as well except use 20/40/80.Screen Shot 2018-08-09 at 12.51.29 PM.png5GHz Channel Bandwidth

After you are done, you can log out of the gateway. After these, hopefully, it should help bring some improvement to your wireless, unless if your channel bandwidth settings match these above.
