My setup is as follows ( pretty basic ):
- Comcast is my ISP since I moved into my house.
- Various Wireless/Wired Routers connected to the Cable Modem ( currently a Netgear WNDR4300 router ).
- Wireless Connections : Various Devices such as Laptops ( MacBook and Google ChromeBook ), Smartphones ( both IPhone and Android ), Wireless HP Printer and Tablet ( 1st Gen IPad )
- Wired Connections : Laptop
The problem that I have is that the Netgear Router would hang after a few days where ALL Wired or Wireless Connections would be down. Since I cannot connect to the Router via the Wired or Wireless connections, I cannot troubleshoot the issue with the router. When it's down, I have verified that the Wi-Fi signal that is being broadcasted goes up and down ( using my Cell Phone Wi-Fi Analyzer ) when I lose connection. When I check my Wired Connection...the LAN connection cannot be established.
I looked at various options to troubleshoot this that could be causing the router to hang:
1 ) Finally swapped out the old Comcast Cable Modem.
- I had an old Cable Modem.....so I finally had Comcast send me a BRAND NEW ( not refurbished ) Cable Modem. It's a different Cable Modem model. With a new router and Cable Modem, it would hang between 2-4 days as opposed to once every 1-2 days for the old Cable Modem. When the router hangs like this....I am able to verify that if I bypass the router and connect my laptop via Ethernet to the Cable Modem directly......the Internet Connection from Comcast is still up but the Netgear router was simply hung.
2 ) Changed various Routers.
- Prior to this month, I had a Linksys Router for the last 2 years where I would lose connection after 1-2 days. I thought that it was the router that was bad. So, I swapped it out with an OLD Netgear router that is a few years old....same problem ( surprisingly ) where it would do the same thing after 1-2 days. I got a new Netgear WNDR4300 Router. Did the same thing but it would last a few days longer before hanging. I returned it and got the same router from AMAZON thinking that the router that I received was simply bad. Same result with the brand new router. Same result with varying lengths of stability with 4 different routers.
3 ) Changed Router Settings on Netgear.
- I changed the MTU Size to 1400 from the default of 1500 and we got the same result. I then lowered it to 1200 and will see if we get any improved results. I had thought that it was maybe some computer that is next door that is simply causing the problem by trying to connect....so I changed the Wireless Connection login/password and disabled the WPS Login Access. Same results where the Router would hang.
4 ) See if the Devices connected is causing the Problem.
- Since I have various devices that connect to the Router, I started looking at the devices that would connect that may cause it to hang ( maybe some software or App on those devices is causing a problem )...since there will likely be some device that is ALWAYS connected to the router on a 24x7 basis. I had thought that I had narrowed it down to my Hard-Wired LAN connected Laptop ( not using a Wireless connection ) but then the Router hung the other day when I was out for the day....with no Wireless or Wired Device connected. I left the house and the router was up and running...I then return later in the evening ( at least 8 hours ) and the router was hung with no device attached during that timeframe.
5 ) Checked Router Logs.
- When the router hangs, I can't connect to it to see what happened to the router as the connections were lost. If I reset the Router....the logs get lost and I can't see what happens. When the router is up and running, I can check the logs and only find some DoS attacks ( common ones from Google, Yahoo, youtube, etc. ) and some stupid LexMark Device trying to connect to my Wireless Connection ( which I think is harmless ) but all of the "lights" are still on in front of the router.
So this is where I am now.....changed Cable Modems, while using different routers, no log files that suggest any hacking of any sort and I don't think the problem is with the devices connected that is causing it to hang....but getting the same result regardless of configuration or device used.
Has anyone encountered this issue?
I am at a complete loss as I do not know what is the cause of the Router hanging. At this point, I am inclined to think that the Comcast Cable Modem is doing something to my router ( or vice versa, regardless of which Router it is ) and over the course of time....the router hangs. Something that is causing the router to hang.
