Phone interfering with internet

[Jeffwilson99]

Hey, every time we use our phone, our internet gets cut off. We're on broadband, via a wireless modem. I though it must have been our ADSL Filter, but we got a new one and it still happens. not really sure what the problem is. It's a Thomson TG585v7, if that helps.

 

Any ideas?

[Sy_Accursed]

I'm going to go out on a limb and assume you have more than 1 phone socket in the entire house; and judging by your use of "our ADSL Filter" in the singular only 1 of these is filtered? (probably the one attached to the router?)

 

If so this would be your problem, ALL phone sockets must be filtered; regardless of what they connect too.

[Jeffwilson99]

Yeah, only one is in use though. I thought of that, but we only use one, cos we only have one phone.

[Hegelstad]

Cellphones are alot handier and just as cheap ;-)

[Dracion1]

Yeah, but if he's using ADSL he may as well have a landline anyway. Save all the hassle of signal, battery, higher charges etc.

 

You need a filter on every single thing that connects to the phoneline regardless of what it is that connects in. If you've just got the phone and the router, and they're connected to the same socket, then 1 filter is fine; otherwise you need filters on every single thing that's connected. Is it possible you've got anything else connected to the phoneline as well? Stuff like some Digital/Sky TV boxes, alarms, just check them and make sure.

 

If that fails, I'd try contacting your internet/phone provider.

Wireless phones?

Not quite, the xDSL modem should not be filtered.

Not always , it depends on your internal wiring. - MY ADSL modem iis filtered and works fine, i'd say about half of our customers have filtered modems, half don't.

 

It's possible it may not be a phone, I've seen DirectTV and other TV that connects to a phonejack for programming updates cause similar issues.

 

Heres what i'd tell my customers

 

Unplug everything that goes into a phonejack - Run a straight DSL connection from the wall to the modem - No filter. if it syncs up - (if not, filter it) Plug in one phone and filter - place a call - do one device at a time and you should have the device pinpointed down

[Jeffwilson99]

Well I'm certain that nothing else is plugged in. And it definitely is the phone, we don't have any problems while it's plugged in until someone rings us, or someone presses talk on the phone. Hmm guess we'll just ring our ISP.

What kind of technology does your company use? You should never have a filter on the cord going to a DSL modem (an inline splitter with a filtered and unfiltered side doesn't count as having a filter on the modem line cord, assuming you are plugged into the unfiltered side). DSL transmits on a much higher frequency than POTS so a simple filter on all phone lines that cuts off all higher frequencies would prevent getting noise on phones, and I just have never heard of a filter doing the opposite, I don't even see how it would work.

I don't know, but my parent's have to have a filter on the modem as well, so there are different technologies. Anyway, me being on cable internet, I don't have to worry about that.

Ensure all phones, extension bells, faxes, answering machines, alarms, sky boxes etc. all have filters.

 

One trick used with the 3 wire ringer system (UK and some other places), is to disconnect the ring wire (number 3) where the master socket feeds the extensions, as the ring wire tends to unbalance ADSL.

 

One other suggestion, is to turn off the modem router, make a call, them turn it back on with the call in progress, then if there are some ADSL sub bands sufferring "suck out", it may be able to avoid them.

I'm curious about that now, do you remember what the filter said on it (if anything)?

Does the phone just happen to be a cordless model? The reason I ask is that I have a similar issue with my wireless router (whenever the phone was in use the wireless internet dropped massively in speed. your case may be that it seems your router is next to the base station unlike mine.). If you do have a cordless phone look in its manual for the technical specifications to see what frequency it uses, because if it is a 2.4ghz (or a 5.8ghz) model that is likely part of your problem, which would require you to get a phone that does not use the 2.4ghz frequency, move the phone base station away from your router, or upgrade your networking devices to 802.11n

 

Edit: This is assuming all the computers being unable to connect to the internet are connected through the wireless network, if they are directly wired to the router, then this is not the issue. Also to give a brief explanation of what this problem is specifically, that model of wireless router only operates on the 2.4ghz frequency band, which if it matches a cordless phone's frequency results in interference between the two devices

Exactly what I was thinking. However, moving to 802.11n won't fix much either unless the OP moves to the 5Ghz frequency.

He could try using it for a while while it is wired to the modem as well, or just check to see if the light on the modem indicates that he loses sync when someone calls. Either way would tell us if it is wireless interference or not.

 

If it turns out to be that you could log into the router and choose a different channel (use 1, 6 or 11) and that might work.

No, Unfortunately I don't remember, and I'm not going to take an 8 hour trip to go check. What I remember though is the filter for the modem was different than the filters for the other things.
