I have an SMC Barricade 7004VWBR Wireless Router and am experiencing oscillating signal strength including dropping of the signal all together. This has worked fine for a long time and the problem has just begun. I have reinstalled the firmware (same version that I already had) to no affect. is there anything that I can be doing or is my router kaput now?

Re: Intermitent signal strength
It is not unusual for the radio transmitters to fail in wireless routers after a year or two of use, especially if they're used in a location with poor ventilation or dust buildup. "Kaput" is probably a good term for it, but it would be worth finding someone with another laptop to try connecting through your router...just to verify that it's really a problem in the router and not in the wireless adapter in your computer.

There are a few things thatcan cause you to lose wireless connection with your wireless router.1. Weak signal strength,check the signal strength on your wireless card. If it is weak move thewireless router away from brick or concrete walls and if possible locatethe wireless router higher up.2. Have you secured yourwireless router from people near your from unauthorized access? i.e. change thedefault password, setup encryption use WPA2 or WPA, change the default SSID,and turn off SSID broadcast, and for added protection, enable MAC addressfiltering which allows only the MAC address/es of your wireless card/s toconnect to your wireless router.3. You could be gettinginterference from electrical sources such as air conditioners, arc welders,washing machines etc. If so, the power supply to the wireless routers andcomputers etc should be connected to a surge protection power board, betterstill connect your computer equipment to an UPS (Uninterrupted PowerSupply). 4. Check the channels ofthe wireless routers and access points in your area and change the broadcastchannel on your wireless router to an unused channel or one that is currentlyused but has the weakest signal strength. This will minimize interferencewith your wireless router from other wireless routers and accesspoints in your area.
We have satellite Internet. They say everything is OK, but every few days I have to unplug my modem from the satellite, reboot, and everything is OK again. So I put a timer on mine, and it reboots every morning about 3.
check if this problem is with both wired and wireless computers, if not with the wired..only wireless has problems, check if you have any other wireless device operating in the same frequency of the router..if s, turn off other devices and check b.cos that me interfere your w/ls connection, if wired is having the same problem, connect modem straight to the pc and observe the connection, so that you can isolate problem..
just a few things that can be checked, firstly in the routers settings look at the transfer speed of the router(not the connection speed) and see if it's set at 108MBPS, if so your wireless network cards on your pc's may only be able to connect at a maximum speed of 54MBPS, unless you have the latest 108 or 125MBPS g type cards.
Secondly you should be able to check the wireless signal strength by the icon in your task bar or software you use, as if you have thick walls or objects in the line of the signal from router to pc's, the strength drops and can read low and therefore cause you to lose internet connection entirely.
You can also try changing the channel at which the router runs, normally this is channel 2, but trying channel 11, which is the farthest away from appliance interference may give you better results, but both router and network card channel numbers will have to be changed.
