I've gotten used to re-booting my Speedtouch wireless modem-router when the connection fails. I know there's probably settings and such that I should set to avoid this but after trying to do so and not getting any real satisfaction, re-booting works every time. Or it used to. Now I find that I have to re-boot my Imac G5 (running Tiger). anyone else have this problem?

I use the NCF for my DSL and I do find that I have to reboot my combo modem/router from time to time.

It should not be necessary to reboot the computer.

When the connection drops, have you tried using the "Assist Me" button in the OS X Network dialog?

As for the modem/router, who is your ISP? Do you have a static IP? Can you check your modem/router log to see if you are the victim of a DOS attack?

Rebooting the modem/router is good because it can clear problems caused by firmware bugs and will most likely change your IP if you're not using a static address. Changing the IP means you temporarily hide from the botmasters and script kiddies.

Thanks for the help.
I also use ncf.
How do I check if I have a static adress or not? Is having a static adress better (than a dynamic?)?
I've tried the assist me feature but it can't bring back my connection. I've never heard of a DOS attack> I am aware of the log on my router/modem that monitors attacks so I'm guessing from what you're saying that this is what you're referring to. I'll check the e log as you mentioned and re-post if anything shows up.

A static IP is one that is permanently assigned to you. Very few ISPs supply static IPs, but NCF will give you one if you pay an extra $5 a month. There is no advantage to a static IP unless you are trying to run a server, and most ISPs don't allow that anyway.

A Denial Of Service (DOS) attack occurs when an army of machines try to connect to your machine all at the same time. It floods the connection and makes it impossible or very slow to do anything. DOS attacks are usually targeted at web servers or mail servers that "the bad guys" want to cripple. It is highly unlikely that a non-server machine would be attacked unless you had some "friends" with a strange sense of humour.

Magma did offer static IP addressing, as do Primus and NCF. I don't recall if Sympatico did. I don't know about Rogers.

DOS attacks could be perpetrated by anyone, whether for seriously criminal reasons or just to test new DOS code. When you visit a site, the site gets your IP address. Visit a bad place and they know who you are for as long as your connection persists (or for a long time if you have a static IP address). Port scans can happen to any high-speed connection: Bad Guys want to gain remote control of computers with high-speed connections.

Do you have another modem and router that you can try in your configuration? Maybe there's a problem with your Mac's network card.

Please note that I said most ISPs don't allow you to run servers. Most will charge you extra for a static IP.

Quite right. In my programmer's brain, I didn't think that someone would want a static IP but not want to run a server. I personally have never encountered an ISP who provided me with a static IP but told me I could not run a server.
