LAN & WAN Basics

This is one of the most frustrating problems that a broadband user faces. The ISP will probably blame the router. The router vendor will probably blame the ISP. The solution usually lies somewhere in between, but no one seems to want to help.

Random disconnect problems are generally hard to pin down because there are so many variables to consider in both your ISP's network and the router you use. The main way to attack the problem is with good old disciplined troubleshooting techniques and lots of patience. We don't have a sure-fire fix for you, but these troubleshooting tips should help:

  1. As much as it's a pain, get the router out of the loop and see if you have the problem with just one computer attached directly to the Cable or DSL modem. If you still have the problem, at least you'll only get the run-around from your ISP!
  2. If the problem goes away without the router, reconnect the router and upgrade your firmware to the latest revision. This is usually available from the router manufacturer's support website.
  3. While you have a normal connection, log into the router admin pages, and take a screen shot of the Status page, or at least write down the WAN IP, Gateway, and Primary and Secondary DNS information. Save this in a handy place next to the router.
  4. If your connection is being dropped multiple times per day, it may be that your ISP is forcing you off because they don't like routers connected to their network. Try using the MAC address cloning feature of your router and change the WAN MAC address to be the same as the one on the computer that was connected before you added the router.
  5. Next time your connection drops, first look at your cable modem or DSL router's status lights and make sure they are indicating normal operation.
  6. Next, before you unplug or reboot the router, log into the admin pages and check the Status page again. If the IP address is missing, you've somehow lost your DHCP lease. If your router allows you to do a DHCP Release and Renew (buttons are usually somewhere on the Status page if you have the function), try that. If the IP address information comes back, then you shouldn't have to reboot the router, but you may need to reboot or do a DHCP Release/Renew on your LAN's computers to get them working again.
  7. If your router has a keep-alive or auto-reconnect function (especially for DSL connections) try enabling it.
  8. Try to note if there's any pattern to the disconnection. Weather, time of day, power interruptions, running a particular application, etc. Keep a written log so that you have data.
  9. Speaking of power interruptions, try plugging the router and cable/DSL modem into at least a good surge protection strip, but preferably a UPS (Uninterruptable Power Supply). Prices for decent UPS' have dropped so much that it's not worth messing around with anything less if you even suspect power glitches or problems.
  10. Finally, do some research, to see if others have a similar problem. The Hardware forums on dslreports are a pretty good place to see if you have company in your misery.

Happy hunting!

  • Intra-VLAN visibility GS724T switches
    I have been asking and researching this VLAN issue for some time on this forum and elsewhere. I have configured my test network as shown in the attachment.

    1. I can see from VLAN 5 out to the Internet no problem.
    2. Any device outside VLAN 5 cannot be seen from outside the VLAN 5 and vice versa - that is fine also

    PROBLEM: I cannot see from VLAN 5 on 1 switch to VLAN 5 on another switch.

    I have not configured any Inter VLAN routing and would prefer not to do so. When I...
  • Need help setting up a separate WiFi behind VPN for Roku/Netflix but regular WiFi for the rest
    Here's my situation - I have the ASUS N66U router running Merlin. I also have PIA setup. I've found that PIA slows down my connection tremendously when it's on, so as a solution, it'd be great to enable it only on one of the WiFi networks and use that for Roku etc, while still having a non-VPN connection for everything else. Is there a way to do this?

    Hi guys,

    I am not sure if this is the right discussion to post and ask for a VPN recommendation so kindly direct me to the right link if I'm wrong. I've been using Cyberghost for months now and still can't decide to get the paid membership as I'm always looking for a good VPN provider. Recently, I've stumbled upon another VPN website VPNWise www.vpn-wise.com and I really like the look of the website and found it interesting. It says it can unblock blocked websites especially streaming...
