Question about Toshiba DOCSIS Cable PCX1100 Modem

Random Disconnect: PCX 1100U

I have a Toshiba PCX1100U cable modem. My cable company is Cox. My computer is an iBook G4 (Apple). I am frequently disconnected from the internet. The first solution tried: disconnect a FON router. Didn't help. Second solution tried: change splitter for internet & TV. Didn't help. Third solution tried: Cox cable man came out and said the modem was shot. These guys are always trying to sell you something new (and expensive) so I'm suspicious. He checked that the signal was strong coming into the house and at the cable to the modem. He checked all connections. Do I need a new modem or is there a fix?

Re: Random Disconnect: PCX 1100U

Toshiba 1100 modem are no longer compatible with any service providers anymore. The reason for this is Toshiba quit making cable modems and no longer supports them. Since they no longer support their modems, they don't write firmware to make them DOCSIS 2.0 compatible and since most service providers use 2.0, your DOCSIS 1.1 modem will not function correctly. Actually what is really happening is the 1100 modems cannot correctly decipher the 2.0 and are constantly changing their transmission power levels. You definitely need another modem, and if you are using Cox, ask about their refurbished ones for about 20 bucks.

That's a hard one to say, you won't know unless you purchase a new modem and install it. But I have seen cable modems just quit, so it does happen.

Hi, I’m facing one issue with D-Link (DCM-202) Modem from last week. The internet connection frequently disconnecting with interval time less than 10 min. I have checked with service provider COM CAST...

Is this a new issue or a recent harware/cable change or did this use to work and now has the disconnect issues.

Ensure that your cable has NO Splitters (especialy outside) from the Drop outside to your modem.

Check all cableing between Computer and Modem to Cable Drop.

You can also look at the Modem Status Page to check your UpStream and DownStream signals. You may have to have someone come out to check out the line running from your house to the pole (or pedestal if its underground)? Many factors can cause an outside cable to deteriorate, and when that happens you can end up with alot of signal leakage and frequent disconnects. And that goes for both overhead and underground lines. Good Luck, and post back if you need more help. (try to include your Modem Status Logs)

Modem will connect to router but not to computer

This is mostly because it has not adapted to the changes when using another device aside from the router, especially a router. What I have done with internet modems is when you are removing a router, or if you are installing a router is allow that modem to be shut down for about 10 - 20 minutes before you use other devices it does not recognize right away.

Hope that helps............

Toshiba Cable Modem PCX1100u

OK. First of all you do not need a special or seperate driver for the Ethernet port. Its factory loaded with your OS.

All you need to do is plug the Ethernet cable into the LAN port on your HP Desktop and then into the LAN port (not the WAN port) of your cable modem.

The second thing is if its only a cable modem, then I suggest you proceed with caution as there is NO built-in firewall on a cable modem. Yes you will get on the net, but you are likely to be attacked with virus the moment you connect. I suggest you check very carefully whether the cable modem (if that's what it is) does/does not have a firewall as you would be very unwise connecting up like that.

Next, forget USB connection to the router/cable modem. That technolgy we've moved on from.. Your Vista shodul be 'plug n play' adn should configure the router for you. obviously that bit isn't so slick on yours.

Let me know how you get on..
