Please help me solve this problem.
About four days ago, our network began dropping connections when more than one device was added via either a wired or wireless connection.
CenturyLink DSL's tech support says my internet service looks fine from their end and modem lights seem to indicate incoming signal is fine.
Router: DLink DI-614+ - 128-bit WEP with Mac address filtering and upgrade to most recent firmware.
• Dell desktop WinXP with Windows firewall
• Dish Network box
• Blu-Ray DVD / Netflix streaming box
• Dell laptop Win7
• 2 android phones
The connections break on both the wired or wireless devices once more than one device tries to connect. For example, I'll use the hard-wired desktop computer, but then when I power up the wireless laptop, both computers break connection and go through a seemingly endless connect/disconnect routine. If I use only one device at a time, the connection seems to be normal. For example, I can stream Netflix to the TV, or use the desktop PC, or the laptop via wireless connection, but not at the same time. Again, this is new all since Saturday.
When the desktop disconnects, I get the popup "A network cable is unplugged," and I can't reach the router via my browser. If I ping the router, the request times out. The router seems to have all the correct lights on, but they do flicker or blink. The router isn't where I see it while I work, so I have no idea if the lights are blinking in an unusual manner.
I have reset the modem, rebooted the router, and unplugged it from the power source then waiting a while and reconnecting before rebooting. None of that has helped. I have not done a factory reset.
Things that may or may not matter:
• We've had a lot of thunderstorms in the past few weeks, but the router is plugged into a surge protector.
• Router was new around 2004.
Have I left any pieces out of the puzzle? Any thoughts?
Thanks very much.
