Author Topic: When access goes down, unplugging ethernet connection to modem fixes it  (Read 3840 times)

Hi all. I'm new here, but have a perplexing question I can't seem to find the answer to.

About three weeks ago, my internet access would go down randomly anywhere from 4 - 10 times a day. Sometimes for just a few minutes. Sometimes for an hour or three.

When it went down, I'd bypass the router (D-Link DIR-655) and connect my laptop directly to the modem via ethernet connection.

I thought it was a wireless problem at first, but even my computers connected to the router via ethernet connections, and my VOIP phones connected to the router, would go down.

I've recently found that when it does go down, if I go to the modem and unplug the ethernet cable that goes to the router, and leave it unplugged for 15 seconds before plugging it back in, then internet for all my computers and VOIP phone would come back on about 30 seconds later.

Why would just unplugging the ethernet connection from the router to the modem make internet access get fixed? Is my router dying? Or is there some DNS setting I might be able to change to make it more stable? I'm not very well-versed in this stuff.

Thank You.

Welcome!
What Hardware version is your router? Look at sticker under router.
What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
Are you wired or wireless connected to the router?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Try single mode G or mixed G and N on 2.4Ghz and single mode N on 5Ghz?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI, WLAN Partition and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Check cable between Modem and Router, swap out to be sure. Cat6 is recommended.

Maybe someone can review your router settings with you using teamviewer if your interested. Its safe and secure.
