If this question is in the wrong place I apologise, today for the second time in a month I have had to switch of my modem because my computers cannot connect to the net. When I restarted my modem they can, has anyone any idea as to what is causing this problem? I thank you in advance for your answers.

It's an external 56k modem?

Hmm.. I would do.. maybe.. switch off the modem. (at least for maybe 15 mins.)
After, reboot of the PC.
If the OS is complete loaded, switch on the modem. Wait a few mins.
Reboot again the PC.

If it work then, fine.
It it don't work, maybe damaged.

It could be maybe also a connection prob.
All cables correct? Also the DFÜ*/TCP-settings correct?

But before you kick the modem to the trash, wait for a more specialist-answer. ;-)

EDIT: ** maybe 'dial'-settings in english?

as painful as it might be, your best bet is to speak with your ISP.

Have you bought anything new lately? Like a cordless phone that might be on or near the same frequency?

No I have not brought anything lately and my ISP have got no ideas I only seem to have trouble in July/August like line dropping before I had this problem something to do with re-sync the line. Maybe they are doing something at night with the exchange would like to go cable etc still on the same copper lines that have been in this bungalow before I moved in 39 years ago.

I can sympathise but not help much. I had a similar problem suddenly started with a Netgear DG834V2. Tried swapping with another borrowed Netgear DG834 and exactly the same. I have a work ADSL as well as home and now have a 3COM and a Zyxel installed and have not had the problem since. (The modem seemed to be working Ok - and could be pinged remotely but just periodically/randomly stopped sending data in and out) A restart made it work for a while.

I assume some change was made at the exchange which the old modems couldnt cope with (and no newer firmware for this version) but the likelyhood of getting my ISP to admit/sort anything out was highly unlikely so I took the risk and tried new hardware.

My ADSL is pretty poor - lucky to get 2Mb/s as we are a long way from the exchange.

I've run into several cable modems that were losing sync and require a power cycle to get reconnected. In one case the modem itself was going bad, the other 5 or 6 were problems with the "provider side" cabling. Either the coax itself between the d-mark and modem, or a "Y" adapter or end-to-end splice that were inline were causing the grief.

It may just be getting old. Chips get old and fussy after long periods of continuous use.
Memory chips don't clear properly and require power down to reset.

At work (US Dept. of Agriculture) we run 30 computer-controlled cotton-grading machines. They are run by Dell PCs with Intel P4 cpus running Windows NT, networked to a Compaq mainframe. All are 2004/2005 vintage. Sometimes they lock up, and sometimes they stop talking to the mainframe, and the only thing that gets them going again is a down-power and reboot.

I've found a surprising amount of routers to be irritating, requiring frequent attention. They've usually got terrible firmware (you've updated your router's firmware, right?).

My Motorola DOCSIS cable modem is plugged into a Linksys WRT54G V4 router. The router is not the greatest out of the box, but since its operating system was based on GPL code there are lots of open-source alternative firmware files available. Tomato is fantastic - nice user interface, lots of features, and the current version has never crashed on me. (Uptime is in months. It's not higher mostly because the unit's been unplugged a couple times.)

Note if you want to go buy one of these, don't get a WRT54G new-in-box. It will be a newer revision that won't accept the right firmware (it's now based on some closed-source thing). You can, however, buy old WRT54G units on Craigslist for like $10 or buy a new WRT54GL for a few bucks more than a new 54G unit - it has the expanded memory necessary to install the cool stuff.

I have a DSL wired modem that was locking up every week or two. I moved the power connection to the UPS and changed the failure time to once every few months. If I am going to be away from it for a while I just do a reset on it before I leave to make sure it doesn't fail while I am away.

I have a Netgear WPN-824v3 router that stopped accept IP addresses from an outside source when I gave the router an address other than the default one, It's possible I could give the DSL modem a Verizon branded Westell 6100 series rev H DSL modem a lower address instead, maybe. It is possible, But I'm not going to try that right now.

I'd replace the modem. The normal lifespan of these modem is about 2 years, and even less if you have no surge protection for it. It depends a little on the ISP but usually you can get a new modem and usually also the router from them for free. Such connectivity problems are rarely caused by settings, but instead usually by faulty hardware and/or wiring.

I had another modem so I checked it I could not get onto the net, so I switched of the router and then 15 minutes later switched it on and I could. Was told by my ISP that the router was answering their ping or something they did so the problem was likely my computers, wondered if it was or maybe it is a glitch in my system that makes the router and my machines not answer on and another.

I used to have similar problems when on 56k dial-up. Have also had similar problems after switching over to broadband with various routers (D-link,Netgear,Safecom).

Since getting into the habit of switching off the whole network for 30 min once a month, no more connection problems.

Using 3x 10 socket extension towers, so after shutting down rigs, just hit 3 buttons & all equipment powered off making things easy (& the quiet is unbelievable).

I abandoned dialup in 1992 and I never looked back, Of course dialup will eventually come to an end and I think that will happen soon enough.

The company that installed my modem said that the best thing you can do when you don't get a connection, is to pull out the plug and leave it for about 10 min. Then you plug everything back in. I had the problem about 4 times and every time it all got back to normal. When you get the same thing, I guess it's a problem with the company's wiring.

With some modems, One only needs to flip a switch, This one can't do routed bride or DHCP which is what I pay for, So the modem can only do bridge mode and so I use a Linksys 8 port router/switch to do the DHCP duties until I can get a new wireless router/access point, But that isn't for today as I'd need about $47.30 for the mini pci-e card and the wireless N draft 2.0 router. But until then the Linksys will do.

Flipping a switch or unplugging mine wouldn't do any good. Silly thing has a battery backup in it. :-)
