What is a bonded channel signal


A 'bonded channel' is where the modem combines two or more channels together, for increased bandwidth.
The first light <Power> should be green, indicating power is on.
The second <Receive> light can be green or blue. When it is steady green, no bonding is occurring, (less bandwidth). A steady blue light indicates that the modem is using more than one channel for downloading. That is too say, it is bonding(higher bandwidth). That is the preference.... (If green or blue, and flashing, modem is still setting up....).
The third light <Send> can be green or blue. When it is steady green, no bonding is occurring, (less bandwidth). A steady blue light indicates that the modem is using more than one channel for uploading. That is too say, it is bonding, (higher bandwidth). That is the preference.... (If green or blue, and flashing, modem is still setting up....).
The fourth light <Online> is green, only....
If green and flashing, it is scanning for a connection.....
If green and not flashing, it is finished scanning....
The fifth light is the WiFI indicator of network traffic. (It also is used for WPS pairing, which I doubt you will use. Just stick with the WiFi indicator function...). It should be green, normally..., or non-WPS....

If #2 is blue, and 3# is green, normally...., I suspect that there is too much loss in your in-house system of wiring, and splitters. If that is the case, try putting a 8-12dB 'tap', in series with the whole house. That way, the loss is minimized for your modem to 'send' high bandwidth stuff upstream to the cable guys.... Be sure that the modem is connected to the 'tap' port, the house to the 'out' port, the cable company to the 'in' port of the tap block. I pasted a couple of examples of taps, at the bottom of this, to show the port labels. The tap loss to the rest of the house, is minimal to how well everything else works. I get a +15dB signal from the cable company. But, too many splits, left my modem in low speed upload mode. By-passing the splitters of the house, by adding the tap as only loss to modem uploading, my blue light always stays on. I also added an UPS, to cover power failures, and glitches. That was a well spent $50 special!

I have linksys wag 120n modem,when i switched on the modem internet led shows red and port 1 led also shows red,after 1 minute gone red,then starts working modem,and several times gone my networt show


The best way is to just reset your modem once and then reconfigure to make it work properly. But please beware you need to backup your settings first because after resetting all of your setting will be gone.

My modam siemens c2110 not open 192.168.1.1 &link no show.pleas


Connect your router to computer with ethernet cable then you can access it with following default link. http://192.168.1.1 or http://192.168.0.1 or http://192.168.15.1 or http://192.168.2.1 If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it. Then it ask for user name and password. Type user as "admin" and password as "admin" or "password" or blank. Then you can see configuration page of router. If you are still not able to access it then press RESET button for router for 10 seconds so all settings defaults .Then you can access it with above default ip. Then reconfigure wan settings and lan settings enable wireless if you want to use wifi Then save settings and restart router Then connect cable from internet service provider to WAN port of router and connect ethenet lan cable from computer to lan port of router. . Let me know if you need further assistance. Thanks for using FixYa.

I plug all the cord in the back of the modem.... the power light blinks, an then the dsl, an thn the ethenet light then cuts off all the lights, for those three, an start all over again an again.. never...


If the modem was supplied by your Internet Service Provider, telephone them for Technical Support, either to trouble-shoot, or to replace the modem.

Obviously, they want to keep you as a customer, paying them money every month. So, they should replace the modem "no questions asked".

Losing connection


I assume this is a cable modem? You need to call your cable company and have a trouble ticket created. I worked for the cable company installing cable for quite a while and I bet my paycheck the signal getting to the modem are below specs and that's why the modem gets dropping the internet connection.

Hope this helps.

2WIRE Single Port DSL Line Filter


i think when you purchased the 2wire modem it usually comes along with 3 sets of single port dsl line filters, try out those other filters see which one works. if the local network light doesn't come on, (are you using 2wire 1000 series?), check the network adapters in your computer, this usually happens when you are using lower versions of OS. try the power outlet in the kitchen / bathroom, if power light doesn't come on, push the reset button for 30 secs. if power light is still off or red, then you may need to replace the modem (check if it's still under warranty, if not you will need to buy a new one.) also you should be using the same power adapter that came with the modem, check the specs. sometimes if the modem is more or less than 3 years old, they could get defective especially if it's often affected by sudden power surges.

Speedstream 5200 modem


Open the following link --

speedstream 5200

Download the manual from the link and review page 7 for ethernet connection.

Notice particularly the back of the device. There are four connection points to plug things in the one on the left with DSL is where cable with the phone connectors connects the phone jack to the speedstream 5200. On the right the round connector with the pin is where the power goes. Next to the power connector to the left is a USB connector. In between usb connector and the DSL port is an ethernet connector. One way to avoid the need for the USB software os to use the ethernet connector bu connecting an ethenet cable (wider connector that fits snugly in both ports one on the Speadstream 5200 and the other probably present on your computer.

USB driver including VISTA (if you prefer)
