WNR2000 VOIP constantly getting cut off and speech transmission problems

Asked By 200 points N/A Posted on -


I have Netgear WNR 2000, cable router  for VOIP. I constantly get cut off, from speech transmission problems. WNR2000 has no ` DISABLE SIP ALG option, that will help me solve any previous problems on earlier routers. 

I need to fix this problem because I'm talking to clients everyday and  I don't want to give them a bad impression. In  the meantime, I am using my landline to communicate with them. This was working perfectly for a year and I can't figure out how to correct this problem. 

Any help will be greatly appreciated.

Thank you so much.

Hi Larry,

What application or software are you using for your VOIP? Is it installed on a wired or wireless computer? Below are some possibilities that could affect VOIP connection:

  1. Slow internet connection – you could run a speed test to check if the speed (through the router and directly to the modem, this way you would know if the internet speed caused by the router or just the provider itself.
  2. Intermittent Internet connection – to further isolate the problem, you can do the same step, you can test VOIP directly to the modem and through the router. This way you would know if the problem only happens if you’re connected through the router. (Applicable if VOIP software is installed on a computer)

Doing the steps above would let you determine, which device causes the issue. If the issue is with your internet connection, you could consult your internet provider about it. If the issue is caused by your Netgear router, you can perform basic troubleshooting steps and determine if it’s a hardware problem or just needs few router configurations.

You can try lowering your security and enable QAS in the router, prioritizing VOIP service. If you’re using WiFi, you can check if your network is secured. Check if you have other wireless devices, which could cause interference (e. g. cordless phone, baby monitors or any wireless device which uses 2. 4Ghz frequency), perhaps you can test the VOIP connectivity, with those devices powered off.
