We spent a week without internet. My DSL went down Thursday the 12th. That happens now and then and they are usually pretty good about getting it back up. However, it was still out Friday after work. I suppose I should have called right then, but we had things to do and would be out 'til late, then Saturday there was this family outing. Long story short, I didn't make the call until Monday. I was told they could get a tech out Thursday morning. Thursday evening and no tech. I called and was told that the "ticket" was pending and that they may still get to it and if not surely Friday morning.

I got off early Friday and got home about 1:00. No tech had been by. I called and they said they'd put a "code blue" on it and I should get a call from the local dispatcher by 3:30. Nothing.

Saturday morning I call them before I got dressed and got a song and dance about them being people short and a heavy load. They looked up the ticket and said the tech had noted that he would get to it between 9:00 and 10:00. At 11:30 I got a call telling me he would be here in about 15 minutes. I got my internet back about 2:30. In the process, the tech replaced my modem and had to go back "downtown" and check the ports. It took three tries to find one that worked.

Now I have a problem with my home network.

I have the computer hooked directly to a Netgear model B90-755044-15 modem/router. From there I have 20 foot Cat5 cable going to a Netgear switch GS605. From there I have my TV, DVR, Home Theater and a VoIP phone (MagicJack). The problem is that this set up worked with my old modem and router and now nothing beyond the switch is visible to my computer and when I try to do anything with the devices they report that the connection failed.

Any ideas?

Modem

The tech replaced your modem? One that you owned, or they owned?

If it was yours, it shouldn't have made a difference to your line.

If it was a new one of theirs then it is probably in default mode and you'll have to connect to it directly and configure it to see the rest of your network.

There's usually a web page which the modem will put out, likely on a fixed address. This is often 192.168.1.1 or 192.168.1.100 but YMMV. Try looking on the bottom or the back, there's usually a label telling you how to connect.

I can't offer more advice, I'm sorry, since my own setup is different.

I have to ask the simple tech support question...

Is your extended network connected to the new modem correctly, or at all? I'd double check the ethernet cord first thing to make sure it is appropriately input, and if the modem has multiple ethernet in/outs, and the router dial-in doesn't do any good, then try different ports to see if it makes a difference.

In addition to 192.168.1.1 to get into your modem, if your extended network is based off another modem/router you may be able to call into it as well via 192.168.0.1 to see if the two are even communicating. You have multiple potential failure points in your network, so the only way to know for sure what is happening is to start with the new modem and work from there, testing each diagnosing each potential failure point 'til you find the one that's your culprit, like christmas lights.

The old modem, (which I'm not convinced there was anything wrong with) and router are back in their respective boxes. and the Cat5 to my switch is plugged into the new modem/router. I even thought of the bad port aspect and changed it to a different port.

Last December, I changed from a Westell VersaLink 327W Router/Modem to the setup I had before my DSL went down. With the Westell, I had three Cat5 lines from the router to each; TV, DVR and home theater. I upgraded the Westell because it was ancient and I needed to add the VoIP phone. Locally, (Best Buy)I couldn't get a router w/modem, so I went with the external modem and Linksys router, adding the switch so I'd have room for the VoIP phone.

Linksys router

If you still have it, try putting it back in the setup. Reason - stuff worked with it, and if you have fixed IP's, they still should work with the values set in the linksys. Only problem would be if the modem and the linksys are using the same ip range. But then every thing should work anyway

But before you do that, try this.

Turn everything off, and wait 5 min. Then power the switch back on. Once it's back up and blinking on the connection to the modem power up the other devices one at a time, PC last. Wait until each device is fully started. This will give each device a chance to get re-assigned a valid IP address for the (presumed) new network range.

I have some other ideas if you are still down. PM me. No need to extend this thread.

if i'm reading correctly,

if i'm reading correctly, that modem/router thingy has four ports -- there's about 8 possible ways of plugging two things into a 4-port switch. try them all; costs you nothing and may reveal one or more dead ports. (the first step would be swapping your computer and switch; if the computer stops working you've found a bad port.)

Home network

So the Netgear model B90-755044-15 is new from your ISP and the GS605 is the existing one that used to work? Are you comfortable logging into your modem/router and changing settings?

Yes

The switch is from my existing set up and them modem/router is from my ISP.

I've been into the page for my new modem/router. I don't know how to get into the switch, or even if that's possible, or even if there are setting to a switch.

The real problem is the modem/router came without any kind of manual.

No Manual

The no manual thing seems to be the new "normal" now-a-days: You need to go on-line to read the manual!

BUT, how do you go on-line if the gadget is not working? How can you make it work without reading the manual? How can you read the manual without going on-line? How do you go on-line when the gadget is not working? ... and so on etc.

That is a real catch-22 situation right there!

The other issue is the default configurations on these gadgets. They are so well known, that they constitute a serious security portal (not just a small hole). Unfortunately many tech-people (from big companies) are severely challenged when they are confronted with a custom configuration. And their favorite solution is to factory reset the config of the gadget. Even if it stopped working months after the last config update.

Well, I hope you do get your network back to working order soonest.

Home network

I think you can see the manual for your modem/router here http://www.downloads.netgear.com/files/DM111P%28U%29v2_UM_06....

I would be interested in seeing if, on the LAN setup page (page 1-9 in the manual above figure 1.5) if the DHCP server option is selected. The answer is hopefully yes.

I am assuming that your computer's network cable is plugged into one of the router ports on the modem/router and your switch is plugged into one of the other ports on the modem/router.

And no, in all likelyhood you can't log into your switch unless it is a very expensive switch (we're talking thousands of dollars here).

I am assuming that, since the modem/router was replaced, you have powered each of the devices connected to your switch off (count slowly to 10) and then back on.

IP-Range

If i remember right, netgear tends to use 192.168.254

If the other devices are not set to DHCP - its highly probable that it wont work anymore..... just change the Range to the old one......

Check DNS settings.

Check to see if the DNS settings for the devices are you are using are set to "auto". They might help you. Also, try using a network switch between the router and the devices. That also might help.

While BCTS was down for maintenance

While BCTS was down for maintenance, the whole situation resolved itself without me doing anything. The only thing now not working is the DLNA server from my television. I think that my be resolved by simply redoing the set up on my computer. I'll give it a try when I find time. It's not a high priority
