Thanks for your reply.

 

The M7350 is v. 5.

 

I'm not going to be able to test this until October, so will get back to you then after I've tried your suggestion.

 

Many thanks.

Hi, I am also experiencing the same issue as @P40.

 

I was previously using the EDUP 4G Router (EP-AZ800). This router was giving me 30-40MB download, 6-8MB upload. I was getting any support on this product so I switched to the tp-link AC1200. I set up this to have the exact same settings e.g. LTE only, same channel etc. I am getting a far inferior upload speed, I'd be lucky to get more than 1MB. All hardware is the same except for the router. Firmware is also updated to the latest version on the AC1200.

 

I have also been through this post but still no change => https://www.tp-link.com/uk/support/faq/2843/

 

Any ideas?

 

Thanks.

I eventually found a quick solution to this. Not very technical, but after simply moving the modem a few feet to a shelf by the window, it now reaches consistently amazing download speeds of about 80 Mb/s and upload of about 20 Mb/s. I'm no expert, but I reckon that even a slight relocation of a few inches seems to make a big difference to speeds and consistent signal strength.

  @P40 thank you for coming back to me and great to hear you solved your issue in a non-technical way.

 

I have done some more investigations and some tinkering in the admin console and for some reason my signal strength jumped from 25% to 75% and my upload speed improved to about 10MB - still not great but better than it was. I made the following changes:

 

1) switched the Network band from '3' to Auto and saved the changes and then

2) performed a Network Search again and it found my existing provider and I saved those settings

 

Not sure why the signal strength dropped so much but after those changes it seems ok now.
