VoIP Modem Problems??

I can't get my Other House Phones to work with This Modem System...Only the Phone right next to my Computer works??
The Clearwire Service told me to Plug-in an Adapter to Line 1 on the Modem(Linksys Phone Router// Model SPA2102-SF) that's a "splitter-2 to 1", then Plug In My Computer Desk Phone, and Hook up the Other back to the Wall Jack...They said this would tie my other Home phones to the system, except when I do that EVERYTHING goes Dead.
When I signed up for this, I was TOLD that This system would work with ALL my Home Phones, but it's Not!!
HOW? can I get this to Work properly?? I have a 2-Level House, with 4 Phones Upstairs, and 2 Phones Downstairs,
2 Phones are Wall-Mount, and the others are Desktop (3 of these Phones are Higher End Phones, Cost a Few $$$ to buy them).,...

    No, No Filter on the Phone I Use, it's Plugged right into Line 1, works Fine...
    When I had DSL I had Filters that were Plugged in to the "other" Phones, and I tried Those but to no avail, got the Same Thing DEAD...???
    So, what Type/Brand/Model of Filters would I Need for a ClearWire System?
    The Phone that works is ONLY Plugged into the Modem, NOT the Wall Jack
    ALSO, My Outside Line that comes into My House from QWEST is still Hooked Up to the Trunk Line in My House, would I Need to remove that from the System??

    My "Previous Post" addressed this...However, I do NOT have a Filter on my Phone next to the 'puter, it plugs directly into "Line 1" on the Modem...
    So what Type/Brand/Model "Filters" do I need to get??
    My Prior DSL Filters do NOT work as I tried them with this Set-Up, AND the Qwest Phone Line from Outside is still Hooked up Inside the House, is that going to be an Issue???

    Do you have ANY insight/experience on Analog/Digital TV Converter boxes??

    You need to have a filter at each wall socket which has phone connected to it, just like you have next to the computer I assume.

The line coming in from your old provider of phone is causing your problem, I am a phone tech for cable company and I find this all the time . your old phone provider if still hooked uo is push a small amount of voltage onto your in house wireing even though it does not have dial tone. just unhook your test port on the old interface and this should fix your problem .dsl filters will also cause a prblem , make sure all filters are removed.

    as to phones not working in house , the other thing that could be causing it is if the phone jack you are pluging into is the same jack that your dsl was feeding could be on the black/yellow twisted pair instead of the primary line wich should be red/green. open that wall plate and see if you are on the same color as another jack in the house. sometime dsl will be dedicated line.

SOURCE: Clearwire VOIP ph adapter + Can only connect 1 phone downstairs

I disconnected my incoming phone line and connected my VOIP line 1 to my R11 wall phone jack. This feeds the signal to all phone jacks in the house.

I also use the VoIP to fax and send data using my PC modem.
For Fax
Use *99 as a prefix for any number you are faxing or dialing to.

My internet keeps disconnecting, never had this before, the internet disconnects, i restart the router manually and internet is back up for about 5-10 minutes and it disconnects again. Everytime i look...


There could be a couple of causes for this issue. Your internet could be degraded when it gets to your house causing disconnects. You will have to contact your Internet Service Provider in order to have them resolve this issue. Normally, they will replace splitters and may even replace lines outside of your house. You could also be having problems with the modem directly. The may replace this. You could also try to upgrade the software on it. Click here for the update page for Arris.

Typically, I recommend you unplug the router, plug the computer directly in the modem and see if you still have the problem. If you still have the problem then you know it is just the modem. If the problem resolves itself then you know the most likely culprit is the router.

I would also recommend that you update your router firmware as well. Do a google search for the brand name of the router and go to the companies website, look in the support/downloads section for updated software.
--If possible, try a different Ethernet port on your router. You may have a bad port.
--Take out and reinsert all Ethernet cables on your network. Loose cables can cause disconnects.
--If possible, replace the Ethernet cables. Bad cables can cause this.

Lastly, you could be having an issue with the Network card(NIC) on your computer. Network cards are either built into the modem or external(a card you insert into the motherboard). Using the process of elimination and the steps above, you can hopefully narrow down the problem to one specific component of your network.

Let me know if you have any questions.

Comcast Digital Voice/ADT alam system

The 2 jacks on the back of the Arris modem are labeled "1/2" & "2". The first jack labeled "1/2" means that the jack is capable supporting 2 different phone numbers, a line 1 and a line 2. The second jack labeled "2" means that it is capable of supporting only a second phone number. Therefore your 1 phone number is working correctly from the port labeled "1/2".

There are different types of phone splitters. It is possible that the one you used may have been to split lines 1 & 2 on a single jack into two seperate jacks. Take a closer look at the splitter and see if the 2 ports are labeled differently.

Hope that helps.

Have system for voip. Only can't hook up the

Try getting a router that has one in/4 out between modem n voip. Your voip unit should have an RJ45 connector to connect to router, not your computer. The USB connector might be to connect the voip to a different type of router, and will not be used. The 2 phone connectors are for two different phone lines that your voip provider can provide you with.

2wire modem not broadcasting wireless signal

are the lights on the modem detecting any connection? is your line still programmed for broadband? if your modem is connected at the phone exchange and the connection is at your house and all and none of your computers can connect to the net, not even the primary computer and you have called your technical team for broadband (can be company policy sometimes to call them) you may need a replacement modem. Tech support should do a ping and other tech things to try to get you connected. you may have a faulty modem which if it is new then you should be entitled to a warranty replacement. if it is a simple setting on your computer they should be able to resolve this, i know that when vista first came out there were a lot of support issues with bband providers being able to support the users.
