Internet disconnects randomly?

[Stevo505]

I don't know why, but my wireless internet (2WIRE890) randomly disconnects then reconnects. Sometimes it doesn't connect back so I have to unplug the internet card and then plug it back in. Can somebody help me?

Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.




Please give an exact description of your problem symptoms, including the exact text of any error messages.

• If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
• For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
• Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
• If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Type the following commands on separate lines, following each one with the Enter key:

PING 206.190.60.37

PING yahoo.com

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

ISP: AT&T
2WIRE, 2701HG-B
TP-LINK, TL-WN321G
Wireless
(I think WEP, but am not sure)
Windows XP Home, Version 2002, Service Pack 3
Opera

It sometimes disconnects and then reconnects itself.

I don't know how to do any of those but I know this is the only computer doing it.

I also want to add that when I answer the phone the internet disconnects.

Obviously, you have DSL. If the phone causes issues with the connection, you most likely have one of the following issues.

1. Bad filter(s) or incorrectly installed filters.
2. Defective interior wiring.
3. Bad modem.
4. ISP signal problems.

For interior wiring and filter issues, here's how I install DSL accounts.


Purchase a DSL splitter and install it at the telco NID (Network Interface Device). This is the place the telephone lines come into your home wiring, usually either in the basement or outside near the other utilitiy connections. Run a direct line from the DSL port on the splitter directly to the DSL modem. Connect all of the other phone instruments to the telephone output of the DSL splitter. All of the DSL analog side wiring should be CAT3 or better twisted pair from the telco service entrance to the DSL/ADSL modem. You can use one of the twisted pairs in CAT5 cable if you have that on hand. The splitter I've used in the past is the Wilcom PS-36, it's good for any DSL/ADSL service worldwide.

This is as good as it gets for DSL installations, and will usually solve in-house wiring issues.

Here's a good detailed description of the process: DSL Wiring Upgrade Tutorial
