Hi,

Here's the equipment:
Cable modem
Linksys router
PC

The router is wireless, but I have 1 of the PCs in the house (there's one other PC plus a laptop) that gets "hardwired" Internet access (in other words, plugged into the Linksys Wireless Router with an RJ-45 cable). How do I set up the hardwired PC, router and cable modem through the surge protector? I am confused as to how all the cables need to be set up in / out.

Thanks in advance.

hi,

essentially, all you need to do is take the coaxial cable out of your modem, which comes from the wall and plug it into the jack labeled "wall" or "in" on the surge protector. then take another coaxial cable and plug it into the surge protector coaxial jack labeled "out" or "to equipment."

it is probably not 100% necessary to plug in the router's ethernet cable into the surge protector as well since the backdoor surge would most likely come from the coaxial connection which i mentioned previous. you'd use network protection by itself in an office for example where you just have one cable coming from the wall jack to your computer.

if you'd still like to do it, personally, you could do one of two things. take the cable from the ethernet cable from the router's wan port and plug it into the "in" or "wall" jack on the networking RJ-45 protection. then take a network cable and plug into the "to equipment" or "out" jack. alternatively, you could do the same procedure on the hard wired computer directly rather than between the wan port. so youd unplug the cable from the wired port on the router and plug it into the "in" or "wall" jack on the RJ-45 network jack and then another cable from the "to equipment" or "out" jack to your hardwired PC.

again, i think that will be a little redundant but shouldnt hurt anything. if anything, there may be a tiny bit of insertion loss but nothing too noticeable. the priority is to hook up the coaxial protection as noted above. you'd want to have the surge protection between the coaxial input from the wall and your cable modem.

hope this helps!

thank you very much for the answer. From what you're saying, it seems that if I have all the equipment plugged in to the protector, plus the coaxial cables, etc., then I am well protected. I just wanted to make sure I didn't miss anything!

correct. essentially, what you'd be protecting yourself from would be a surge generated by the router itself which i personally have never even heard of and I am not sure if its possible. the backdoor surge generally would come from the coaxial line from outside.
