View Full Version : wireless disrupts wired???

My pc in the bedroom connects to my (wireless) router through a
"wired" connection through the electrical in my house. I've used this
system for a few years and works *great*.

My daughter got a laptop this week and she uses a wireless connection
to our router. Now we get interruptions to our pc that is wired.

Is this possible or is it just a coincidence? The problems started
pretty much the same day she connected, if I remember right.

It does seem like the problems happen at night. Is it possibly the
fault of Comcast? I know a cable connection can slow when many people
are using it, but I didn't know you could actually lose your
connection.

thanks

What kind of interruptions? How bad? or how long does it last?

It could very well be a coincidence but if I were you, I'd look into it just
to make sure.

Don't know. When your wired PC connection is "interrupted", did you try
shutting down the laptop and see if the problem goes away? Also, when
"interrupted", did you check all LED indicators (on the wifi router or on
your cable modem) to see if there's any traffic between your home and the
internet?

Hi
This is Not a normal situation, you can use few wired, few wireless
computers, and still have a good connection.
Check the Router's manual about DHCP and provided IPs it might be that some
thing is Not correct with the settings.

Interruption to what?

Coincidence. Unless your "router is only giving out a few addresses (DHCP)
and you don't have enough address to cover all the machines. I believe this
is what Jack was asking about. This would not *normally* be the case, but
if someone got into the router's config and screwed around with things it
could be misconfigured by reducing the range of addresses given out by DHCP
to a too small range by virtue of maybe a typo in the config.

Also make sure that your daughter is not connecting to the router with both
a cable and the wireless method at the same time,...choose one or the
other,..not both. That will not cause your other machines to have problems
other than it eats up yet another address via DHCP,...howwever it will cause
her problems because you end up with the same machine having two Nics on the
same LAN segment at the same time. Tha machine can become "confused" about
which nic it is supposed to use and will "confuse" your other machine's
ability to properly identify the daughteers machine when it "appears" on the
LAN

That is the "Interruption to what?" question. Your PCs do not connect to
the Internet (ever). They connect to the router,...the router connects to
the Internet. If Comcast drops the connection the router becomes
disconnected to the Internet and the PCs loose access to the Internet,...but
they are still connected to the router and still have access to the home's
LAN.

Comcast does not "run" your Home's LAN,...they simply provide the Internet
connection to the building.
