I have a desktop hard wired to a Netgear Wireless N Router, and two laptops, both with the same Linksys Wireless G notebook adapter cards. One laptop connects about 95% of the time to the network without any problems. My wife's iPhone does the same. My other laptop used to connect to it about 20% of the time, the rest of the time I would have to unplug, turn off, turn back on, replug etc, etc my router and cable modem to get it to work again after most reboots or not using it for a day. Now, it isn't even connecting at all. Even when the laptop is literally 5 feet from the wireless router, nothing! I went to my 192.168.0.1 settings page from my wired desktop and reinstalled the router and refreshed the settings back to default, but the problem stays exactly the same. I even switched the Wireless G notebook adapter cards between the 2 laptops, and the laptop that worked 95% of the time still did so, even with the other laptop's card. And of course, the laptop that had issues still had issues with the other card in it. Now its gone from 20% of the time down to 0%. Also, I have the same issue of working at first for a while, then sporatically not working until I unplug and replug everything back in with a different iPhone. The cable modem is working fine, everything is only a month old and is not damaged, so I'm pretty sure its some kind of software issue or IP address assignment issue. I don't mind setting up each laptop with its own static IP, but I have no idea how to do this, nor do I know if it will even help me out. Could someone please guide me step by step through the process on how to fix this?
Come to think of it, there is a possibility it may be a range problem. I read an article that said if your wireless router is positioned upstairs and you are trying to get access downstairs, the signal is most likely bouncing out of the upstairs bedroom down the stairs and into the living room. I had always thought if I put it on the upstairs floor, it would go right through the floor/ceiling, but maybe I was wrong. The only problem is that it WAS working much better in the past, it has recently been more flaky, but it was never PERFECT before either, 20% of the time. After connecting the poor working laptop directly to the router with an ethernet cable (hard wired), then opening up Firefox, then disconnecting the hard line, it seemed to kick the wireless connection back into gear... at least while it was upstairs. Then I took it back downstairs and restarted it, and no connection once more. Tomorrow I'm going to try two things to further test what is going on.
1) Bring the laptop that works most of the time to the same position downstairs and see if it connects or not when restarted.
2) Reposition the router as close to the upstairs portion of the stairwell as my power outlet will let me go and see if that helps
This will at least tell me if it is a signal issue, which I would have originally been very suprised to hear, but after reading about the signal going down the stairwell instead of the floor, sounds more probable.
Hopefully my results will help some of you with the same question as I'm sure many of us have this problem. In the meantime, any advice would sure help!
Worst comes to worst, I'll have to fish an ethernet cable or two down my wall... I'm sure theres a how-to guide somewhere on the internet for that.
I am still wondering one thing though: When it used to work (20% of the time), it would ALWAYS get an "excellent" signal strength and all bars would be green. I was downloading at up to 200Kbps. If it is indeed a signal issue, why would it either be super fast perfect connection, or no connection at all? Anybody who can answer that gets a cookie! I'm thinking maybe it has to do with the very basic wireless adapter card on my laptop pinging BACK to my router. Maybe it can download fast but not upload fast. hmmm.. anybody know anything about that...
OK, tried the other laptop in the exact same location, and it works flawlessly. Just for fun, I tried to see how far the signal went. Every square inch of my home and patio gets a Very Good or Excellent signal. I was actually able to walk 15-20 yards away from my house in each direction before the signal was lost. But I noticed it steadily decreased in strength the further I walked away, as it should. So I've determined that it is absolutely NOT a range issue. Its some kind of connection issue.
