R6300 router loses internet connection when GS205 switch is connected
I have a R6300 router that has been working great for a number of years. I have a number of devices wired directly to it (Magic Jack, etc.) and everything works flawlessly. The 2.4 and 5G wireless ...

Well, it happened again. Not sure what the cause is, but after a few days of everything working, everything died on me - no wired or wireless internet connectivity. I unplugged the power to the GS205 and everything is instantly fixed. Then I plug the power back into the GS205 and reconnect everything one by one and the wired connections work. Truly makes no sense to me why this keeps occurring, but at least I have a fix for it now.

Jeremy,
I saw your post earlier but could not immediately think of an explanation. Since you specifically asked for my input, can you describe exactly how everything is connected? Perhaps you have a forwarding loop somewhere.

Thanks for responding TheEther. Regarding your question, I have my R6300 router connected to my Motorola cable modem. One of the ports on my router runs to a GS605 switch and everything works fine. I just connected a GS205 to one of the other open ports on my router. As mentioned above, when I first connected it everything was fine - it worked for about a week flawlessly. Then out of no where I lost all connectivity - wired and wireless. After a good bit of trouble shooting, my issue resolved itself as soon as I disconnected the new GS205 switch. I've since tried reconnecting the GS205 and as soon as I do I lose all internet connectivity - wired and wireless. Makes no sense to me. Hoping you have a suggestion on what I can do to get this working.

Does connecting the GS205 to the router with nothing else connected to the GS205 immediately cause the problem?
Do the link lights on the GS205 look ok?
Have you tried swapping cables around?
Have you tried running a packet sniffer, like Wireshark, to observe the traffic on the network?

Well...I tried what you suggested. I connected the switch only ot the router with no devices connected to the switch...everything was fine. So then I connected my desktop to the switch but in a different port (normally 2 but this time put it in 5)...everything was fine. So then I connected my laptop as well, but in a different port (normally 3 but this time 4)...everythying is fine. So now everything is miraculously working again, but I gotta say...this doesn't make any sense to me. Don't get me wrong - I am very happy, but can you explain why plugging the device into a different port could make my issue go away?

If the only difference is that you plugged the desktop and laptop into different ports on the GS205, then I have no explanation other than the possibility that either port 1 or 2 is broken.
OTOH, if you had done something like connect a GS205 port to a GS605 port, then you would have created a loop which easily could have taken down your network. So, the mystery remains but at least things are working, now.
