| Overnight lock-up Hi guys,
My Pre N has been behaving well, with no drop outs all day, and I use a VPN which is pretty sensitive, so I know that the connectivity has been rock solid.
I turn the wireless on and off a couple of times per day.
Most of the time, I turn down a UPS with the router on it each night, and then boot it back up in the AM. All works great.
For the past couple of nights, I needed to have a unix workstation run on a problem overnight, so the router stayed on. In the AM, it is locked up; the wireless light blinks, even though the wireless had been shut off the night before, and the router will not answer for web admin.
I have to pull the plug and then plug it back in.
Anyone else seeing this?
Thanks,
R |

| No problem for me I don't have this problem at all. I leave my pre-N router on 24 hours per day and have never had it lock up yet in the two weeks that I've had it. My Linksys router would lock up every week or two so I'm hoping that the Belkin is an improvement. |

| Can you guys run a test for me?
I think I narrowed this down a bit.
I have a Motorola Cable modem that has a very cool switch on top to isolate it from the internet. At night, when I am done for the day, I usually switch it off, even if I keep my home internal network running.
The cable modem is still "on", but it does not provide any outside connectivity to the router.
I think that if I leave it on, the router stays alive.
Thoughts? I should be able to use this thing as a router, even if it has no input from the WAN port, don't you think?
Regards,

It may be the same issue I had for a while. Check out the router firewall log and see if your I.S.P I.P.s shows under DoS attacks. My router reported numerous bogus DoS attacks. Every IP listed was from my ISP. I had PPoE at the time. They lessened when I got DHCP instead. They went away completely when I put my TA as the firewall. I take it people with a static IP do not experience this issue as much. |

Hi Eric,
I reviewed your replies and the strings in which you took part in.
I don't see the specific issue that I am referring to. Could you cut and paste the text for me into this string?
Issue: Router is rock solid for all connectivity until left over several hours without a signal from the cable modem.
Thanks,
R |

| I recall having the same problem - took Motorola cable modem
off line by pushing that button on top, and couldn't get connection after attempting to bring it back on like with the same button. Needed to reboot modem. Since that time, never used that button again, and of course, no problem. |
|
| I also recall reading a thread on another board where the cable modem IP was listed on the firewall log. The Belkin thought it was being attacked by the modem. |
|
| Thanks for the comments, guys...
Just as a test, I disabled the firewall and turned the modem off last night.
The box was still locked up this AM, and I had to cycle the power on it.

Turning off the firewall does nothing for the DoS attacks. Do you see IP listed in the firewall log as DoS attacks? What are they? |

Yes, if you activate the Motorola switch [killing the WAN interface] the Router will stop polling the WAN port after a period of time. To get the WAN port on the Router to Respond after you have activated the Motorola switch [make alive] all you have to do via a wired connection is open a Command window, issue a IPCONFIG /RELEASE then wait 15 seconds and issue a IPCONFIG /RENEW ... your Router should now operate normally.
The issue is not Pre-N related -- there are some issues all related to how Your ISP deals with polling your Motorola Cable Modem Interface and How the Pre-N deals with a silent WAN port.
IMO that Motorola switch you termed as cool is not cool in anyway -- in fact its my opinion that its far from cool.  I would suggest not activating that switch. Plus I would also suggest that you leave the Pre-N router running 24/7 because devices like the Pre-M operate better when they are hot. The Pre-N routers SPI Firewall and NAT interface does a excellent job of protecting you from incoming traffic. Outgoing traffics is subject to your disciplines.

| Hi David,
Thanks for the info...
It seems easier to pull the plug on the router and then plug it back in...
From my perspective, this is a bug. It has nothing to with my ISP. I have had a router from every major company, and have never had this problem. There is no reason on earth why this box should not be able to act as a hub for my internal network - what if I don't WANT a WAN input, but rather just a good wireless internal one? I have two unix workstations and a PC wired directly, and a couple of PCs on wireless. When it is time to stop working, I like to sever the tie to the Internet. I should be able to do that....
Your information is much appreciated, and I am glad to know that it is not just my unit, but don't help Belkin rationalize an obvious bug.
Regards,
R |

When it is time to stop working, I like to sever the tie to the Internet. I should be able to do that.... Perhaps I misunderstood how YOUR Motorola Cable Modem works. I have worked with the Motorola SURFBoard Cable modems and each model that provides the Standby Button -- the switch you term as cool -- has the following characteristic:Internet service is blocked because the Standby button was pressed. If this light is on, all other lights are off. If all lights are off except the Standby light, the cable modem is in Standby mode. Press the Standby button to reconnect your Internet service. So as long as the Standby Button is active Your unix boxes will not be able to communicate over the Internet regardless of whose Router your chose to use as the gateway. Insofar as How a Router reacts to an INTERFACE that’s gone silent is another subject that takes too much time for me to explain -- and you're certainly entitled to believe whatever it is that you chose is the correct methodology
Insofar as the Pre-N acting like a LAN Switch -- from my perspective there are no issues [I have done work on many of the Belkin Pre-N devices] -- why you are having issues is beyond my ability to provide further meaningful input.

Re: Overnight lock-up I have to admit, I did not read all the posts and replies. have you tried a new router? have you tried using the Belkin as an AP and use another switch instead of the belkin? |

Re: No problem for me Hi David,
All I want is for the Router to not crap out when there is no input from the WAN.
I want a functioning internal network while the cable modem is in standby mode.
This is what I could do with Linksys and Dlink, but not with the Belkin Pre-N.

This is what I could do with Linksys and Dlink, but not with the Belkin Pre-N. OK, then I strongly suggest that you and everyone else who see this as a legitimate issue to write the U.S. Networking Tech Support people at usnetsupp@belkin.com and request that they have the firmware adjusted accordingly -- if enough people write in and complain I suspect they would make the adjustment --- although what you may be requesting is not standard operating procedure because of a unique [and useful] feature provided by Motorola. The fact the Dlink and Linksys routers are not bothered by a WAN port gone silent over extended periods of time is not a material argument -- although perhaps it should be |

| Good advice, mozerd - I'll do that.
We have probably inconvenienced too many electrons on this matter already, but let me belabor the point a bit longer.
What if I wanted a wireless network for file sharing and resource sharing (like printing, etc) in an environment that was NOT connected to the internet.
I disconnected the motorola modem altogether, and the results are the same. If there is no input from the WAN, the modem locks up after a few hours. This is not because of the funny switch on the top of the cable modem.
Do you think this is a valid, possible use for the modem? I would probably include this as the MAIN issue in my email to Uncle Belkin.
Does anyone else need the Pre N to function in this matter?
