We had a lightning/thunderstorm and a transformer blew outside our house. The computer was not on, but it was pluged into the wall and attached to a phone line. Ever since then I can't get online. Computer is saying I no longer have a modem attached to my laptop??? What could have happened and how can I fix it?
Always unplug all telephone equipment in an electrical storm. They are always the first things to go as the telephone cables are generally above ground whilst power cables are usually all below ground.
In this case the LIU would have blown and a replacement is the only option.

If you are saying that a house fuse blew out then the question is why did that happen? If the washer shorted out and blew the house fuse then you have to work on the washer to see why. It might have been the transformer in the washer power supply. If the fuse blew during a storm then it might be lightning damage and that would mean replacing the power unit and the computer in the machine.
But, was the cable/satellite feed protected? Lightning can come in from anywhere, not just the power line. The bad thing about the way cable and satellite installers ground things is, they ground to the same grounding system that the house does, which can backfeed the surge through the entire house - it shouldn't, but it can.
I would, however, contact the maker of the surge strip and attempt to file a damage claim. They all come with a liability warranty of some sort.
You can check the fuse which is internal to the TV, but that requires removing / opening the case and potentially exposing yourself to lethal voltages. Be careful. If lightning hit nearby, it is likely damaged permanently, no cost effective to repair. Might talk to insurance company if applicable.
Lightning routinely gets into copper telephone cables during storms and can overwhelm the fusing protectors at your home and enter a telephone set, causing a lot of immediate damage to the telephone and the user.
Lightning can travel from outside your home to inside your home—and to you—through materials that conduct electricity, including electrical wiring, phone lines, water, and plumbing. These safety guidelines will help minimize your risk.
If you need to use the phone corded phones are dangerous during thunderstorms. Lightning traveling through the telephone wires has killed people. Cell phone and cordless phones are a safer choice, but stand away from the cell or cordless phone's power base
If you have reset both the router and the cable modem and it still doesn't work, bypass the router and try connecting the system directly to the Cable/DSL modem. If your computer works in that situation the router has been affected, double check your connections between modem & router AND between router and computer.
If you still cannot connect, call your internet provider and inquire re: system status in your area. If all is good ask them if they can 'see' your modem. They will check their equipment to see if your modem is connected and communicating with their system. If they don't find it the modem is suspect.
If they can see the modem but you are still unable to connect to the internet via the router/switch, then the router/switch is the culprit.
Of course this all assumes everthing is OK with your computer. Otherwise this becomes a much larger troubleshooting issue. But let's not go there yet.
BIG TIP: Invest in a lightweight UPS or a line conditioner, particularly one that will protect your inbound Internet connection (coax or phone line) as well as the Ethernet port protection you need. In the end it's a LOT cheaper than replacing lightning damaged hardware.
Surge Protectors are of limited value because a majority (80% or more) of all power related electronic issues, especially regarding solid state circuitry, is due to BROWNOUTS, not surges. Something the manufacturers of surge suppression strips & related hardware are reluctant to admit, but that's why they can reliably afford to insure their surge protectors for ridiculous sums.
Apply this same principle to home entertainment systems, tv's (especially LCD & Plasma), game consoles, and any other valuable home electronics.
Upon researching various websites regarding the Model Number for those 2 televisions that blew out, I found a few other people around the US that had the same problem with similar situations. All involving massive thunderstorm power-outages.
It appears that since out TV's are both 5-6 years old, they are worthless, both covered under homeowners but for almost nothing. It's not worth fixing. So, decided to purchase 2 more lower quality televisions as this will most likely happen again when the next storm hits. Thank god we found out that this is a repeat issue before we purchased a really expensive television.
Did you disconnect your dsl connection from the back of the modem? I'm more familiar with cable modems than DSL, but I would imagine they share a commonality: electrical surges coming down the line during lightning storms.
I'm guessing that's what happened to your modem - it probably got surged through the DSL line. Have you called your DSL's support line to see if they have any ideas?
If it's been surged all you can do is replace it. Do check with the DSL company first before you go putting out any major expenses.
