Help Needed

[Uridium]

ive recently switched from BT to EE in the uk and since moving with EE I keep getting this error message

error_connection_reset when im using WIFI

this doesnt happen when I use my mobile phone data and view the exact same website only Via WIFI

sometimes pages work then they wont and so on

Ive done all the flush_dns and all that and the empty chrome cache

But its having no effect and im kinda running out of ideas..

Ive been intouch with EE and they say all is good with my settings on the hub...

watching the youtube help videos ive tried all that they suggest but nothing seems to be working..

Also I only use the windows defender for antivirus and have no third party firewall packs that could be an issue...
