Hi there GTG experts!


SYSTEM INFO:
Home computer (older Dell XPS )connected to D-link Wireless router via ethernet. ISP is Verizon DSL. Using ISP supplied Westell 2200 modem router (set to bridge mode).

PROBLEM:
The problem is that the Internet connection gets dropped several times a session.

DISCUSSION:
Can usually re-establish connection buy running a batch file I created using ipconfig.exe (separate instances with /release, /renew, /flushdns and /registerdns in separate lines). This usually fixes the problem. If not, I just reboot. The problem usually occurs while I have my e-mail client (Thunderbird) and AIM running at the same time but can also manifest itself while just browsing (Firefox and sometimes IE)

This can be quite a pain and should be unnecessary. I tried searching the Forum for "dropped internet connection" without success (too many results to wade through).

What could be causing this and what would be the probable solutions?

Thanks in advance for your help.

There are two two laptops that are occasionally connected via wireless (SSID not broadcast, otherwise open connection, no encryption).

Problem mainly occurs with home computer (whether or not there's an active wireless connections. Tired changing the NIC once and connecting the ethernet to one of the other connectors on the back of the router (D-Link), with no affect.

Jack123,

Thanks for the detailed response. Will proceed as suggested and let you know how I fare, or, perhaps it may be better to repost in the networking forum?

Need to determine if problem is – [Modem] – [Router] – [PC] – [Connection] – [IP] – [NIC] -

How long have you had the [D Link Router] & When did this problem start – 2-3 months, occurs intermittently since I have had it, can not recognize any pattern.
Sounds as if you have or had trouble with the [Router Setup] – Not as far as I can recall. Completed setup without seeing any error messages
Also are you using the Proper [IP Internet Access] – I think Verizon uses [PPPoE] – Yes I am, and Yes it does.

The [Batch File] using – [ipconfig] – sounds as if – the [Westell Modem] & [D Link Router] are using same [IP Address] – when doing the [Router Setup] – Followed Verizon’s procedure for setting the Westell Modem to Bridge mode.

Do you have a [Software Firewall and/or AntiVirus] – And did you – [Temporary Disable] – when you did [Original Setup] – This may have been the [Origin] of Problem – As far as having [Remnants of Failed Installation/Setup] – I use free version of ZoneAlarm (have disabled MS Firewall).

I will reset both the Modem and Router to their defaults and go through the setup process with the firewall off to be sure.

How are you connecting to verizon. Are your name and password saved in the modem? If not, try saving your name and password in the westell modem. Just call verizon...get a tech, and tell them you want to save your info into the modem and make sure it's connected 24/7. Once you do that, you should be fine. :tazz:

Hi sr71000,

Is this the case, even when the modem is set to bridge mode?

Thanks.
