Dect 6 phone sometimes disconnects internet?

[Anubis]

K I'm stumped on this one.
Router is a Linksys wrt300n v1 running DD-WRT v24-sp2 (10/10/09) std - build 13064
and once in a while when phone rings it knocks out the internet connection. Only does this once in a while.
Thought it was the phones so I bought new phones and same issue.
Dect 6 runs on a totally diferent frequency so I'm confused.
I need to run router with mixed as I have a couple wireless cpu's on g but the rest are n.
Am I missing a setting somewhere?:noidea:

Thanks in advance for any feedback.:thumbsup:

I have the same phone set and occasionally I have problems with a bridge that is located close to the phone base station...um! In the bedroom I am connecting to the same router (WRT54G w/DD-WRT)with no drop out problems.

The main house WiFi router (WRT160v1 w/DD-WRT)is a different router and I haven't had any problems. BTW I am using a cable modem with the main house.

If you are running a DSL connection suggest switching your filters around to see if you may have a bad one.

I am assuming that you are not running a VOIP, correct?

I had this problem, I solved it by going to 5.8 GHz phones, they are not in the same band plan as the 2.4 to 2.5 GHz phones and routers and outside of the 5.2 GHz WIFI band for the dual band routers.

You can try different channels on your router and WIFI cards to see if it will help, channel 6 is the default channel.

Running cable.:thumbsup:
no VoIP running.:no:

I'm not getting another set of phones Terryl...:tape:
I have like 4 sets boxed now and I am thinking of opening my own phone store! :tehe:

Try changing channels on the router and cards.. It may help.

Thanks for your help Polly... However base of phone is in seperate room.
I think Terryl may be on the right path.

If the phone freq listed is correct it should not interfere with the router freq. (2.412--2.484 GHz) but something is happening.

Maybe Terryl will let you borrow the phones for a year or so....for a purely scientific reasons of course.


Or better yet, great reason to upgrade to one of those new barn-burner dual freq. routers.....

And how does that fix the issue?
Replacing router if it is sending signal is not necessary.
Settings is what is involved.
Thanks for the input though.

After you started your thread I have been reading thru a lot of DD-WRT post and it does seem to be an issue with the firmware. One thread in-particular has shown some mixed success by lowering the mw output while others have reverted back to stock firmware. Posted below you will find a link to one of the better threads.

While logging into my home router (Linksys WRT160 w/DD-WRT) via my laptop, I noticed that my base station (phone charging in base station) lite up along with another phone that was on a end table by my chair. They both stayed illuminated for approximately 5 seconds. Taking this a little further, I disconnected the power to the router and tried logging in to the same network again and again the phones lite up. I tried the same with local networks that I could sniff locally: two that were opened (no password/paraphrase needed) showed no phone interaction and 2 of the 4 that I put a fake password/paraphrase in had a reaction.

It doesn't necessarily rule out the DD-WRT software but it appears to be more on the GE 6 phone side. BTW my laptop is using an Intel Wireless Wifi Link 4965AGN card.

As the cordless phones get cheaper and cheaper they start cutting corners on the electronics side of things, (the same with WIFI routers) they more then likely are using a wide aperture LO on the phone system that will lock on anything close to its designed frequency and try to establish a connection to the base (or vise versa) a spectrum analyzer would be helpful in troubleshooting this problems but most don’t have access to this type of equipment.

This is why I went to the 5.6 GHz phone system, it would be cheaper then renting/borrowing the equipment needed.

What also could be happening is a secondary frequency is being generated by a third device; do you have anything else running in the 2 to 3 GHz band around your area?

Example:
Frequency A + Frequency B = Frequency C, or 2 times Frequency A + 3 times Frequency B = Frequency C.
Harmonic’s can be very tough to predict and calculate, I use to have a program that would allow you to enter all transmit frequencies in the area, it would do some calculations and come up with a list of what would be produced.

[Pollypurabred]

Yes, I did think about that as I have three different routers running DD-WRT using channels 3, 6, 11 and all 2.4GHz. Although I was logging in/out on channel 6 I do not know what the others two routers were doing. May disconnect all, just for hey of it. and then try different combinations if I every get that bored.....LOL).

[Terryl]

Well 3 routers running in the 2.5 GHz band will make a good mix of frequencies.

If you know the channels you can look on line for a channel list, take frequency A and freq B add them together and divide by 2 this will give you the intermix harmonic.

You would also have to do this at 2 times the frequencies and 3 times as the higher harmonics have a tendency to to the bad job.

I will look for the program I use to use for this, it will spit out all possible combo's, all you have to do is enter the main frequencies.

I forgot to add the 3 WET54G bridges, 2 Vonets, and 1 WRT54G (DD-wrt) acting as a bridge, a 2 WRT54G (dd-wrt) acting as repeaters. Oh yea, forgot to mention the 2 wireless computers. SO if may be easier to turn the power off to all and then start with my laptop.
