What is lynksysn600 wepkey?

WEP is a type of security mode for wireless networks. It is associated with a specific SSID. You have to know the WEP key to be able to use the WLAN that is protected by it. If you own the router, you can change the WEP key in the config. If you do not, you'd need to get the key from the owner.

My Sprint 645 DSL modem (Zyxel SP-645M-A1) recently started freezing. My connection to the Internet stops every 10 to 15 minutes. Rebooting the DSL modem gets it working again. I can still connect to the...

That model of modem was made with firmware specifically for Sprint so ZyXEL would not have any more recent firmware for the unit. That model has been discontinued for some years now and judging from the type of behavior it is showing the unit may be experiencing a hardware failure. Your best option would be to try and find an inexpensive ADSL2+ modem to replace it with.

My speedstream modem wont let me connect with wireless router

high this is a crazey fix but it might work it has done on two of my modems speedstream and speed touch and i track this problem down just so i could post this fix because i know what its like to pull your hair out over thease things its pretty simple and i know idear why it works but it has done for me
firstly if your with a internet provider and they have supplied you with a disk if your lucky it will have modem problem fixing file such as with tiscali
if like me you only get some way through it as it configures your modem hear it is take the phone of the receiver ie hook then it will configure your modem for you
if not lucky enough to have this on your set up internet cd you can still try it
by taking the phone of the hook and then rebooting your modem ie switching it of and on becarfel though it might be best if you closed your computer down first
1) take phone of hook
2)re boot modem
3)tern on computer /laptop
good luck
regards colin

Motorola modem sd 5102 is all ways blinking on send

I work for a Cable company and am very familiar with these modems. When the send light is flashing it means the cable modem is unable to lock on the the upstream channel.

A few reasons for this are.
1. The tuner in your cable modem may have suddenly died
2. The could be an internal wiring problem in your home or some sort of filter on your line preventing it from linking.
3. The cable company could be having a problem

When did this start?

Hope this helps.

2wire modem is not brodcasting wireless

Usually 2WIRE modems are automatically configured to broadcast wireless. If your modem is not broadcasting it can be due to a few minor D.I.Y issue.

1. Access your gateway address E.g in most cases
, access wireless settings, scroll down to see if the ENABLE SSID is checked. If it is not checked, check it and submit settings. Try searching for wireless again and it should appear in your wireless networks

2. Check your wireless channel if its in the default channel. By default it should be in channel 6. Too high channel will not broadbast wireless networks. E.G Channel 13 will not broadcast wireless. Even it does the wireless will not be strong enough.

Hope this may help and solve your problem
