internet/server constantly going on and off

[RWWiley]

Hi,

For the past several weeks (after a couple of months of no trouble), the connection to the internet through the DSL has been weird. When it's working, the speed is as good as it ever was. But the connection gets lost, it will work for a few hours at a time and then go out. There are two ways I've been able to "fix" it: one is to open Network Diagnostics (I am running MacOS 10.6.8 on one computer and 10.7.5 on another), and once I do that often the internet will come back online within a few seconds (the lights for Internet and Server are usually yellow when I first open up the Diagnostics). When that doesn't work, if I turn the modem off and back on, that always works.

But it doesn't seem like I should have to cycle the modem every few hours, especially since this wasn't the case before! It's the D-link 2750B. Thanks for your help,

#1 Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that the final hop (bottom-most line of the trace) might contain a hop with your IP address in it. Remove that line. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.

#2 Can you provide the Transceiver Statistics from your modem?

Thank you for replying! Ok, here we go:

So I see it did not complete-- I ran it multiple times to confirm this, it never completes. As for the transceiver stats, I have the D-Link 2750B provided by Verizon and my understanding is that the stats are not provided (I certainly am not finding them anywhere). But maybe the traceroute is clue enough as to the problem?? Thank you!

Fixed! (thanks live chat technician)

lots of people are having this, or a similar, issue, so let me describe what was done:

1. the modem was reset (not turned off and on, actually reset to factory settings)

2. through the router webpage (typically 192.168.1.1) the firewall setting was changed to minimum security

3. also on the router, for Universal Plug and Play, the setting was changed to "publish all WAN connections"

4. the cord from the phone line to the modem was unplugged on both ends and plugged back in

it's been working essentially perfectly ever since.
