Hi all, I have a dilemma with my wireless internet. I have a D-link DI-524 router upstairs in my dad's office. Our Shaw cable modem is hooked up to it, and my dad's PC is hooked up to the DI-524 router via Ethernet. I have one PC downstairs in the basement connected to the internet via the D-Link DWL-122 Wireless Adapter. In addition, I have 2 MacBooks, and 2 iPhones that would access this internet network also. Both PCs are running Windows XP Pro. My problem is with the PC downstairs in the basement. About a year ago when I first got the router/adapter bundle, the connections were great. I opened up ports for my downloads, and I was getting exceptional speeds. However, problems with the connections starts to arise about 4 months ago. Downloads have slowed down... and I find that I often have to "repair" or unplug and replug the adapter to get a connection. My dad's PC was fine, and my Macbooks sometimes stalls. The downstairs PC was getting so slow and annoying, also for some strange reason, the USB adapter started to clash with my other USB devices. For example, when I plug in my camera or my external harddrive, the internet will fail, and the USB adapter will become unresponsive. So I reformatted it last week, hoping that would solve the problem. The problem did not go away. At first, the USB adapter will still clash with other USB devices. I updated the adapter firmware, and moved the adapter and other devices to different ports, that seemed to have solved the clashing problem. But the internet connection is still unstable. After reformatting, I was trying to download my firewall program and Spybot program. But the downloads constantly stops halfway, no matter which mirror I use. After multiple tries, I finally got the programs downloaded. I ran Spybot and my AntiVir programs and found no malwares or viruses. I finally was able to download Firefox, and the downloads from websites seems to work fine... that is... if I can get a webpage open~ What I'm experiencing now is that Firefox (same with IE) will load a couple of pages fine... then I would get error messages like "page not found".... it doesn't matter which website I try to access. At the same time, my downloads with ABC will continue to trudge along. So it's not that I have lost connection... just that my browsers won't load pages properly. I've tried unintalling and reintalling Firefox. That didn't fix it. Things just continue to go downhill... my downloads with ABC are down to a crawl... about 0.3kb/s... that's ridiculous with a cable modem. And it used to be an average of 90kb/s with ports forwarded. My Macbooks are still downloading fine tho. I didn't do any port fowarding with the Macbooks and I'm getting avg of 15-20kb/s. Can anyone shed any light to my problem? I'm very frustrated. Thanks in advance.
