I'm new on here but I'm sure my network problem isn't new and so hope I can get a bit of help .
I have a router in the office with 3 pc's connected, and a length of ethernet cable, less than 100m, which runs to another part of the building straight into a 8 port switch, call it sw1. Connected to sw1 are 2 wifi access points and another length of cable going into another switch, call it sw2. Sw2 has a tv and another wifi access point connected to it.
My problem seems to be with the cable going into sw2, before using sw2 I could connect a laptop into that cable and it works fine, but the tv would work and sometimes wouldn't. Even connecting to the access point on sw2 is a bother with intermittent connection problems using mobile phones.
All the access points can be seen from the router side of the network even when I can't get a connection on the sw2 side of the network.
Any insight into this problem would be much appreciated.
I take it it is ok to setup the network the way I have cascading the switches and connecting access points or I think you would have mentioned that. I have used several different switches for sw2 and that part of the network always ents up the same after a time - not data.
