I'm having an issue with my Macbook Pro when connected to my home network. I can't load anything in browsers, send messages through discord and can't really do anything online really. The browsers just time out and no messages through discord get sent. I seem to still be able to receive messages through discord.

My laptop also seems to stop other devices on the network from being load or search anything on the internet. The moment I disconnect from the network the other device are able to use the internet as normal. If I use my phone as a wifi hotspot my laptop has no issues, it seem to be just when connected to the home network. Other devices on the network have no issues.

The home network is a Huawei HG659 which I have a Ubiquiti UniFi AP AC Lite connected to. The HG659 is setup in the main house with wifi and the AC Lite is in the external cottage. I am on a ADSL connection.

I have tested my laptop when connected to both and the same problems are present.

I have rebooted HG659 and the AP several time as well as my laptop and the problem is still there. I have also renewed the dhcp lease just in case there was a problem with the assigned IP.

I've had wireshark capturing data and all I can tell from what I saw is that there is active connections happening but I don't really know how to use it properly yet to determine what may be the issue.

My only the only theory is that my laptop is using up all the upload bandwidth on our connection which is causing internet issues for myself and other devices connected to the network.

This has happened before about 2 other times. Last time was about 2 months ago, it just resolved itself after 1 day. This time its been like this for 2 days so far.

If anyone could offer some suggestions or ideas to what may be going on and some possible solutions that would be greatly appreciated.

*Edit*

Forgot to mention I have also done a full system virus scan of my laptop just to try rule of something malicious.
