router fails when i turn on pc

[unwashed potato!]

this week has been a right pain in the back side. my router has done this before but it's random so i've stuck with it. i have wifi fine on my phone, i can use it alll good, but then when i turn on pc which is connected by a cable the net goes. this will be gone until i turn the router on and off again, and turn the pc on and off again in that order. if i do pc first then router doesn't work, if i just do router doesn't work etc.

any ideas what could be going on?

it's asdl is it makes a difference

Dodgy network port maybe, use a different port in router and pc. Test a different network cable between PC and router. Try connecting a different pc if that doesn't work.

What router do you have?
