Call you cable provider for any issues. If not your modem is faulty.

Ive had this modem for a while now. all of the sudden some lights start blinking and sometimes they dont blink at all and thats when i lose connectivity to my internet. ive try resetting it back to default...

Sounds like the signal level drops too much.
Connect the modem in the first cable from outside (without splitters).
Check the fitting (must be clean and shine, the copper wire).

You could have too much drops with your cable installation. You need to put an amplifier.
Or try to eliminate some splitters and renew the fittings.

Good luck.

Rate my possible solutions. Thanks.

Norelco shaver sudden power loss

I hope you are observing the following:- Recharging only when the batteries are almost completely empty. Continuously recharging or continuously using as a corded razor will reduce life of batteries Charge only when the indicator in charge meter starts blinking. It appears that your batteries are gone. Hope you have replaced the batteries with the new ones. Use a good brand

You should get the tablet, and then get some tape, and then move around the wire, and then when it turns on, tape it onto the tablet, and then it should work intill you take off the tape.

Motorola sb5120 trouble

the sb5120 does not have a reset button- you just unplug the power cord and plug it back in to reboot it, it is a modem not a router. click start-run- type: cmd and click ok then a black box will come up and type in: ipconfig and press enter and that should give you your ipaddress of your router if you are connected through a router

Randomly loses power and sometime dies

1st thing to do is have the system tested for the code that caused the check engine light to come, you may also have a fuel pump starting to fail or many other things, the check engine light may be the key. How many wiles on the car?

Can only connect to LAN, no internet access

Check for a vaild gateway address on router,start.run.cmd> type in ipconfig.if you dont have a valid ip or gatway. try a powercycle,turn off modem and then router,wait about 10-20 sec and plug modem back in. check your ip and gateway check for a connection, if that dont work call netgear to see if u have a defaulted router, or take it back for new one if u still have a recicpt.
