Lost network computers and printers after new sky router

[Sam21]

Hi i have been suffering slow WiFi speeds for a while now and sky have replaced my router.

I have two computers both running windows 10 with the latest build

Now since i started with this router i have lost my home network and i have not changed anything on the computer

This is driving me crazy some times i can see my other computer but not able to connect to it. sometimes i can see nothing. sometimes i can see the sky router and sometimes not.

I am not able to see my printer at all on ether computer

My network is set to private on both computers and file and printing is turned on

All i have done is plugged in a new router

Sometimes i can see on my network a device called AirTies WAP what is this please

After doing a google search i found that AirTies WAP is something to do with my Sky wireless booster. is that right

Wow ive got my printers back i don't know how but they are back but not the other computer it says error 0x80070035

Ive done a google search on this but nothing seem to help
