this girl needs some help <sigh>

[lisabette]

DSL is running slow. its slow to start with (the cheapest option = 750K, so thats what i got. i think it may be time to shop around for a bit more speed.)

anyways, for the last two weeks its been running slow. 250K - 350K / 20k-50K.

i cleaned up things, checked the modem and router, called verizon tech support. she told me that things are running fine and full speed ahead when she checked the line. she told me to call the laptop manufacturer, which i am loath to do.

so im check with you all here to see if you have a suggestion. from what i have gathered you may want the following information:

Seems your router and modem are being affected by strong electromagnetic interference from some nearby electrical device.

Ensure they are placed a few feet away from all electrical devices, including themselves. If you are using a cordless phone, disconnect it and use a line phone instead.

[lisabette]

wow. interesting. there is a cordless phone nearby so i will move that. the phone has been very crackly lately, so i bet you are right. ill do some rearranging and then retest the speed. and report back, of course.

thank you very much for your time.

[lisabette]

hmm. not much luck.

i think i have a combo modem/router (westell 327W). so i cant seperate them. but i did move the phone (and unplugged it for good measure) and the answering machine.

since you didnt mention them, i assume a lamp wouldnt throw things off, but would my laptop or its ac adaptor. those are the only things that are in the vicinity of the router/modem.

ill keep trying.

i assume a lamp wouldnt throw things off

If the lamp is using a filament light bulb, then it will not emit interference. If the bulb is those energy saving or florescent type, they will have a starter that will emit interference.

What you can do is to remove all other electrical devices near the router/modem and do a tracert to see if all 3 ping times in hop 1 becomes <1ms.

Then add back one device at a time and check with tracert again. This way, you can isolate the cause.

[lisabette]

regular old bulb. how about the ac adaptor or the laptop itself?

AC adapter, when powered would be. Laptop will not.

Also, do not place router/modem on top of the comp tower because the power supply box of the comp is mounted at the inside top of the tower.

The cracking sound you heard when using the cordless phone means it picked up the interference as well.

[lisabette]

well its up to 579K/72K.

im going to take a break from this and watch lost. my room is a mess now! ill have to reconfigure.

thank you for your help. i honestly appreciate it. ill keep at it and get it figured out.
