Hello and good morning. My house, specifically my telephone and cable modem lines, took a direct lightening hit and now when I turn on my PC the power light just pulses. I had the power supply tested at Tiger Direct and it tested good. The PC was surge protected so I think the damage likely came through the cable modem. PC is a Gateway GT5222E with a MS-7248 Motherboard. I'm leaning towards replacing the motherboard but would appreciate any other, less expensive, suggestions. I do not currently have the necessary spares to move CPU etc around and run tests.

Re: Desktop Power Light Pulses
Try removing all PCI/AGP and RAM cards from the motherboard and disconnecting all drives via their power and ribbon cables too and see if you at least get the boot process to start. if not, that confirms your motherboard is bad.
If it does start but gives errors for the missing components, start putting them back in or connecting them back up one at a time until the problem returns and then you have your failed part.

RJ-11 telephone cable coming from a splitter or the extn. line of your landline phone.
Ethernet cable coming from your Desktop/Laptop connecting RJ-45 port
Most standard ADSL modems have four/five lights in the front :
Power light to indicate electric power to the modem.
ADSL light indicates the status of ADSL sync. When the modem is synchronized with the ADSL line card at the other end of the circuit/loop, the DSL light will be steady green.
LAN light will glow steady green when the modem detects a successful link to a computer or router ethernet port.
ACT i.c. Activity light glows when the modem is sending and/or receiving data on the lan and wan. It will vary between very slow to fast flashing and steady green to indicate lan/wan traffic.
With the DSL light always flashing, it means that either the ADSL signal (synchronization) does not reach your modem, or your modem cannot 'read' the signal.
You need to determine if the problem is from one of the following places :
outside of your house (your land line or ISP equipment) or from the modem;
your telephone-cable inside your house or
one of your equipment;
Try the following manipulations to determine from where the default comes :
Determine if the problem is in your house or on the land line
Unplug each and every equipment which is connected to your telephonic installation (Fax, phones, answering machines etc);
Using the shortest telephone cable (RJ11) you possess, plug only your modem to the main telephone jack of your house.
If the DSL LED still flashes continuously, the problem is somewhere between your ISP's equipment and your house. You should call them and expose the situation. At this stage, you can't do much else.
Determine if the problem is in your house installation If the DSL LED lights up when it is plugged to the main telephone jack, then it is either one of your equipment which is at fault, or the house installation. To pinpoint the problem, do the following :
With all the other equipment still unplugged, try the modem on all the other telephone jacks you have around the house.
If the DSL flashes continuously on one of the jacks, you will have found the source of your miseries. Depending on your ISP's terms and conditions, you will either have to call them of call for the services of a third-party technician to solve the problem.
If the DSL lights up correctly on all the telephone jacks, then your house telephone installation is good. Proceed to the next series of tests.
Determine which equipment is at fault
Plus your modem to one telephone jack and wait for the DSL line to light solid.
Use a splitter (ADSL filter) to plug the equipments you possess (telephone, fax etc) one by one. Verify each time if the DSL LED is still lit or flashes continuously.
If one of the equipment causes the DSL LED to flash, it is that equipment which causes your problem.
If every equipment causes the DSL LED to flash, the it is the splitter (ADSL filter) which is causing the problem. You can confirm this hypothesis by testing each and every ADSL filter you have in your possession.
Replace any faulty equipment and you should have eliminated the problem.
If nothing of this solves your problem, you won't have any choice but call you ISP. Don't hesitate to tell them all tests you will have done.
May I also make some recommendations :
Use a power surge protector (not a UPS though) to plug your modem to the electric outlet BUT plug it directly to the telephone jack;
Make sure your modem is plugged in as far as possible from UPS, television, etc.;
If possible, don't plug the modem in the same electric outlet as other equipments;
Don't use any telephone extension cable to plug your modem to the telephone jack.
Hope this helps you. Let me know what happens next.
If your DSL light is not on, that might mean your modem is not connected to your ISP's DSL network. Check the cabling, specifically make sure the telephone cable running from your modem to your telephone socket is plugged in correctly. If that's ok, contact your ISP's helpdesk and ask them to test your DSL connection. It might be a mass outage in your area or a technical issue with your DSL line.
hello, im confused here, have you a cable modem or telephone line. if you have a cable modem then you plug an ethernet lead rj-45 from your modem to your router.but if you've a telephone line then you have to connect a filter to you telephone box an a rj-11 lead from your filter to your router hope it helps
Currently, the most common way to connect a desktop system to the internet, is by using the network jack to connect to a broadband cable modem or DSL modem. To do either you must have the service from either you cable provider or phone company (For DSL) and have the modem device for the service. Fees run $20 to $50 a month depending on speed you subscribe.
You connect the device to the system using a CAT5 network cable to a RJ45 (8 wire telephone type jack). Some Cable/DSL modems also have USB connection capability for the few systems these days that do not have a built in RJ45 connector To use them, you install the associated software, then connect the USB cable when prompted.
If you don't have Cable/DSL then dial up telephone modem is the next option, this requires a telephone modem that has an RJ11c telephone cord jack connection, most current computers only have a telephone modem as an option, but they can still be bought for around $20 and you will require a dial up internet service (Few remain, one is Netzero in the USA)
First thing to do is unplug your DSL modem and leave it unplugged for about a minute then plug it back in and see if problem is corrected. If not you should contact your ISP tech support. You could have a bad line from the phone company or bad connection in your house. Also if you have filters installed on your other phones you can have a bad filter that is causing interference and keeping yoiur DSL from working properly. You should go to "Start" > "Run" and type cmd and hit "Enter"
In the command window type ping google.com -t (Enter) This will start a continual ping. If you are getting ping times exceeding 70 - 120 ms that could be a sign your DSL is not functioning properly or if you get packet loss. That is when the ping time doesn't return a time periodically.
it is a router. not a modem. you just dont plug a telephone jack on a router because it will not fit. you have to insert a lan cable from your modem to the router, and the telephone jack is inserted on the modem
Generally this is an indication of a modem failure. If there have been any storms in your area, then the modem may have been zapped. The dial tone curcuit is normally the first casualty when a modem gets hit with more power than normal.
Provided that your telephone is functional on that line (Unplug modem, and connect a handset if this is a modem only line and see if the handset gets a dial tone, this is a good check to make sure the line is functional)
A flashing ADSL light on the router means its not getting constant broadband signals. Make sure it is connected to the adsl filter without any extensions and the filter should be directly connect to the main phone socket and not to an extension socket. Also check if the phone socket has 1 or more than 1 ports on it. If it has two port its most likely a SSFP socket which does not require a filter as it is inbuit.If all the connections are fine try changing da filter.
