Situation:
- Charter Cable Internet
- Two Different Linksys WRT54G (802.11B)
- 25 foot SMC LMR 400 Cable
- SMC DI145 Cantenna
- Clear line of sight 6,250 feet (pasture)
- Two remote Toshiba notebook computers with D-Link DWL-120+ USB NICs
This setup worked flawlessly for 14 months. About two weeks ago the connection started dropping intermittently. The drop-outs got progressively longer and longer. Finally the Internet connection stopped completely and I could never get it to return. No trees or vegetation have grown between the AP and the remote workstations. The
25 foot cable was checked with an ohm meter and there was zero resistance. Additionally there are no kinks, cuts, scrapes, tight turns or twists on the cable. It looks new. The lan has always worked perfectly. The "local" wireless also works perfectly within about 150 feet. I called SMC & they sent me a new Cantenna under warranty. I hooked the new one up and had no wireless long distant internet connection for three days. We always have had a Net Stumbler connection with signal strength between 45 and 60 but with no internet connection. Yesterday, out of the blue, we got an internet connection for about 15 minutes then it dropped again.The only thing I have not changed out is the 25 foot cable. Does anyone have any explanations:
-1- Why Netstumbler would show an available network but we still can't connect to the internet?
-2- Why the D-Link AirPlus utility would show the network is available but no connection?
-3- How can I actually check the 25 foot cable?
TIA,
