tschmidt posted : When you say modem reboots what you mean? Is this a matter of losing Internet connection because ISP assigns a different IP address or is something else occurring?

Under normal circumstances residential accounts are configured dynamically. This should be invisible. Assuming ISP is using DHCP to configure modem/router midway through lease your modem/router will request a renewal. This should be transparent with same one being assigned. However it is possible ISP is issuing a different one each time. Why they would be doing that for "security" reason is bogus.

Access modem/router status information pages. Should see one that shows information about ISP connection, may be called WAN - wide area network.

Should see current IP configuration info and DHCP lease. Should look something like this:

Lease Obtained : Tuesday, March 03, 2009 9:06:52 AMLease Expires  : Thursday, March 05, 2009 9:06:52 AM

This came from Windows XP Ipconfig /all command but entry in router should have similar information. If you are not sure post data here. Make note of current IP address and when lease is set to expire. There may also be log file. That may have information about problem.

When problem occurs go back into router and see what happened. Is the IP address different?

If ISP is deliberately changing IP address then booting router so next change happens when you are not using it will hide the issue. Since your friends have not run into this issue (I assume they use same ISP)it is unlikely your ISP is doing this deliberately.

As Rob posted there may be something wrong with router. Before replacing may want to reset and reconfigure connection. Remember doing so will lose anything you configured such as WiFi SSID and password so you will need to reconfigure it.

Let us know how things turn out.

Golgamesh posted : It is a modem/router. On further inquiries it appears that for security reasons Alice insists that the IP address assigned to my router has to be changed every 24 hours. They are unable to specify when that change takes place. Presumably it was during the night, because I never noticed it. We had an electricity cut during the recent big storm here in SW France and the electricity resumed around 2200 hours. While that does indeed make sense, I first installed the router/modem during the day - so why didn't it reboot at the time I first installed the device? No answer from Alice of course.

Does this make sense? Do other countries do the same?

said by Rob:

Your router may be bad. Your router should be able to get a new IP when the lease is up without having to reboot. Alice has no control over your router and cannot force it to reboot.

could be an integrated DSL modem / router combo therefore they *would* have access to it.

Alice (France) reboots my router every evening

Golgamesh posted : I am with Alice (used to be Tiscali) in France. Recently I have noticed that my broadband wireless modem is rebooting the same time every evening. I had not noticed this before, and it is very inconvenient.

On raising the question with technical support I am told this is normal, because every 24 hours the modem gets assigned a new IP number; and that every other provider does the same. I cannot understand this because I have had broadband for several years now and have never noticed it.

I have had conflicting explanations for the timing. The first technical support guy suggested I could change the time by switching off my modem and switching it on at a different time, the implication being that at some time I switched it on at 10 p.m., from when the 24 hours runs. There is some logic to that, because we had a long power cut after the big storm, and electricity did get restored at about that time. BUT when I first installed the modem/router it was during the day, and I never noticed a regular reboot.

The second tech guy I rang said their equipment determined when my modem would reboot for a new IP address, after seeing how much traffic there was on it, and there was nothing I could do about it.

The purpose of reassigning an IP address is said to be for security. However friends I have talked to have never come across this.

Has anyone else come across this? I am afraid I do not trust Alice's tech guys very much on this.
