My router is in two parts, a hub and a vdsl box I believe. it is fibre optic to exchange broadband.
Anyways. I spoke to my provider who had me changing channels. Have been on channel 2 successfully for some hours now (crashes on channels 1,6 and 11) so here's hoping
am surprised it may be a fairly simple fix.
Thanks for the help everyone
These vdsl (or whatever) boxes have been known to overheat, mine has been exchanged once already after 5 months of use. BT are replacing them.
My router is also up to date, these updates are done automatically.
