Download latest firmware. In router web administration panel, go to Administration then Upgrade firmware. After firmware upgrade administration webpage link will break. You will need to refresh. Go to Status tab in the router web page and check the firmware version is correct. Also check the date/time. If the date shows 1/1/1970 the firmware upgrade was not successful. This is a bug that I found. At any time if the router stops working check the date/time stamp in the Status tab and if it shows 1/1/1970 then reinstall firmware. You do not have to perform reset configuration, reset factory settings. My router stops working from time to time and I just reinstall the same firmware and this fixes it. I have manual security setting etc and never have to reconfigure those.

2008 envoy Denali right turn signal and right hazard quit. replaced relay worked for 20 minutes of driving then right turn and right hazard quit again??? LEFT SIDE IS FINE

Sounds like you have a wiring issue ! Maybe when you installed the turn / hazard relay you moved the wiring harness in such away that made it work. Grab the wiring harness an do the wiggle test an see if it works . Mite have lose connection where the relay plugs in, close the terminals a little bit. I don't know what you know about electrical systems on automobiles or I'd tell you to do a voltage drop test to find the problem . Need volt ohm meter an a wiring diagram to do this test.

The turn signals in my 2000 dodge caravan work erratically, some times good for weeks, other times good only for 2 minutes.The hazard signal works fine. What can I do to correct this problem?

It could be several things, since it is all the turn signals, not just one side or the other it narrows down possibilities. Your relay may be dying. You can swap a relay with another already in the box. Just switch one beside it from another plug(verify the numbers are the same. ) If this isn't the problem, then go for the the controller; replace your turn signal control. It is fairly easy to replace and not more than about $50.00.

If you've had this happen with two systems in a row, then it may not be the systems. First, try hooking up the PS3 directly to the TV, or another TV, and see if the issue still occurs. If it does, then something between the PS3 and the TV is causing your issue. Otherwise, call and get it replaced again, and hope the issue doesn't happen again.

Wrt400n connects via ethernet cable, but won't talk wireless

you said every thing that connects with the ethernet is working. that means the wired part of the router is working. check the wireless settings of the router. Open the set up page of the router on the main computer. connect the main computer to the router with the ethernet cable.
change the wireless settings of the router.
WRT400N is a dual band router ( 2.4 GHZ and 5 GHZ)
You can create 2 different wireless networks. Make sure that the names (SSID) will be different for both the networks. For 2.4 GHZ change the standard channel to 6 and save the settings.
Go to wireless security and set the security mode to WPA Personal. set up password for the wireless network. You can use the same password for both the networks. Make sure that the Wireless MAC address is disabled.
Now try to connect to the new wireless network. and see what happens.

Lowrance x96 does not function after 20 feet depth

Your transducer needs to be adjusted so the return signal can be picked up. Some of these have to be super tuned to receive the signal. Also the transducer may be moving ever so slightly when the boat is traveling at speed. You may have some water turbulence interference all contibute to signal return.
