Re: Packet loss and eventual shutdown of port 80 on RV180

kogashuko · ‎12-03-2013

I have been using my RV180 router for about a year now. I have had very little issues with it overall. I have seperate wireless access points connected and use those for my wireless devices.

Recently, I started getting very odd connection problems it started as packet loss and then turned into connection loss. The odd part is that it only effects port 80 or the secured port, 880, if I remember correctly. Thats right, everything else on the network works fine. However, I can not access the internet or the RV180 router via it's ip address to check the status. VOIP, other lan networking, gaming, and bitcoin mining is completely uneffected. Direct connection to the modem works without any problems.

I have tried updating the router firmware but no help.

Each time I have this issue the problem is cured simply by unplugging the router and plugging it back in. Nothing else works because I can not log into the router. This problem comes along once a week or so. I have also tried enabling the logs but I get absolutly nothing when I reset the router and log back in. I have had similar problems with routers in the past becoming "bent" after about a year of use and requiring a replacement. I sort of thought that this wouldnt be the case with the Cisco because it is a good brand and came with a five year warranty. I have also scanned every PC on the network for viruses and malware but nothing was located. The remainder of the devices are IP cameras and such.

Can anyone think of anything that could be causing this?

So I was able to get the logs tonight by repeatedly pinging the router and it would start letting me get traffic in again.

I am wondering if this is some sort of side effect to my solution to the thing dropping connections after 10 minutes seen in this thread

https://supportforums.cisco.com/thread/2157309

The only thing I can think of is that maybe the old sessions arnt being closed? How easy is it to exceed the 10,000 or so connections that the router supports? Thanks.
