Is there a medium between the router and the switch? Maybe a PC?
If not, have you checked the cable connecting the two? Assuming you weren't using the said cable to connect directly to the router before.
i have an observatory that i run about 40 mtrs from my house, i have laid an underground CAT6 cable that links my router to a switch and then from the switch into my computer within the observatory. everything was working fine for 6 months but recently i have not been able to access the internet. when i took the switch out of the path it worked but it did take a while to connect to the internet. I replaced the switch but that didnt fix it. any thoughts as to why the connection would degrade? any thoughts on what to troubleshoot?
thanks
