When I first got AT&T fiber, I was getting roughly 100 Mbps upload and download with my Archer C2300.

 

That was quite a few months ago, and I haven't checked the speed since then because I wasn't having any problems.

 

Recently, I was troubleshooting something with my VPN and I noticed that my upload speed was now only about 10 Mbps, although download was still in the 90s.

 

Since nothing has changed regarding my physical setup, I figured it was on AT&T's end so I called them and had them speed test the fiber modem itself. It was uploading at 100+ Mbps, so the problem must lie with the router.

 

I've poked around in the C2300 settings a bit but I'm not sure what I should be looking for. Could this be an IPv4 vs. IPv6 problem? Any ideas or suggestions would be appreciated. Thanks

I backed up my settings then restored the router to factory default and ran a speed test:

Then I restored the .bin backup and ran it again:

I'll continue to monitor for a few days, but it seems that my issue is resolved. Thank you for your assistance!

If you disable your VPN what speeds do you get down and up?

 

Are you using the VPN server in the router or are you using a suscribed VPN from a third party?

Thanks for the reply.

 

Sorry, I should have clarified...this is with the VPN completely disabled. Actually, enabling the VPN doesn't change the speeds that much, but I disabled it when testing to rule it out.

 

Edit: And it's a third-party VPN also, I've never messed with the router's built-in VPN functionality.

See if the issue is both on Wi-Fi or wired.

 

If this issue is happening on a phone or laptop via Wi-Fi, get a Ethernet cable and test on one of the LAN ports of the router. 

 

Also, see if the upload happens on mutiple devices, and not just one device.

I just tested on my phone and it's getting the same speeds as my hard-wired PC.

What is the firmware build, and hardware version the router is running?

Customers that have had speed issues seemed to be resolve by factory defaulting the router or upload the latest firmware again on the router. You can possibly try that to see if it resolves your upload issue.

Hmm OK, I can try a factory restore.

 

Can I backup my settings, do the factory reset, then reload the settings? Or will that defeat the purpose?

So I've been checking the speed periodically, and the upload speed dropped back down to about 11 Mbps.

 

I ran through the above steps once again (reset router to factory default, import backed-up settings, retest) and the speeds are back up where they should be.

 

What is causing the router to do this? Is this indicative of an impending hardware failure?
