Randomly Dropping WAN Connection On WiFi Router

  • 2

Hi!

setup:
* ADSL modem connected to internet
* WiFi router (Netgear WPN824v2) connected to ADSL modem
* CPU, iPhone and iPad connected to router, CPU wired connection.

Everything has worked like a charm up until a couple of days ago. Now the link between the router WAN port and the modem randomly drops. Stays dropped for 1-3 secs and then connect again. When its really bad this happens with 5-10 secs intervall. This made it impossible to use the network from any of the devices.

If I disconnect the CPU from the router and connect it direcly to the modem and change the IP settings to match the modem network the CPU connects without errors to the internet, iPad and iPhone connected to the router keeps having problems.

Restarting the router does not change anything and it seems to be more frequent errors during heavy load hours, in the morning I have almost no problems at all, in the evenings I cant almost use the wireless devices (CPU works fine as its now connected directly to the modem not through the router).

I havent changed a setting in the last year, it just came right out of the blue.

I have hard reset both the modem and the router and reconfigured them (that I dont want to do again as I have some virtual servers, port forwards, port triggers and so on :P).

As it came right out of the blue without me changing anything on any device and as it seems to be more frequent during heavy load hours I’m suspecting that the ISP is involved, but how can they be (it works fine with devices connected straight to the modem)?

Kind regards
Anders

  1. in the evenings I cant almost use the wireless devices (CPU works fine as its now connected directly to the modem not through the router).

    To me this says router issues. When I’m thinking wireless issues with regard to routers I always recommend you do the following in order:

    1) ensure router has the most up-to-date firmware available. If it doesn’t, download and install the latest and test
    2) firmware upgrade doesn’t fix the issue, reset router to factory defaults and reconfigure
    3) if all the above doesn’t fix it, it’s likely your router is broken and needs to be replaced.

    Considering you tried another router I would contact my ISP and have them double check their equipment. They should be able to remote into the modem and run some diags. It’s possible the modem is bad. However, a bad modem or ISP issues would affect both wired as well as wireless connections. In your case it’s the the wireless that’s having issues so I suspect your router, and the one you tried, may be the issue. To confirm, call your ISP. If their stuff checks out, try a completely different router (ie: not the one from work you’ve already tried unsuccessfully).

    It matters not how straight the gate,
    How charged with punishments the scroll,
    I am the master of my fate;
    I am the captain of my soul.
