I had difficulty before, posted and solved in this thread
HERE. After that fix, all my wireless computers and devices found my network automatically when powered on. At some point, my daughter contracted a malware virus on her Dell, which eventually led to me having the hard drive removed and replaced, so I had to reinstall everything on her PC, including the wireless adapter. In so doing, I restarted the router a few times, and now the router has reverted back to its old behavior of not allowing my wireless computers and devices to connect to my wireless network automatically upon power-up. I called D-Link's support line, and tried to get them to tell me the settings that would allow for that automatic connecting, and I was told that I must just check the "Enable Auto Channel Scan" box. Well, I did that and it hasn't changed my situation: every time I try to use a wireless computer or device while my "main" PC is powered off, my wireless network can't be found, and I must restart the router. What I actually do is go to the router page, look at the wireless settings, and click "Save Settings". Sometimes the "Enable Auto Channel Scan" box is checked as I had it before, sometimes not; I've tried re-checking it, and I've tried leaving it unchecked, but either way I'll have the problem again tomorrow.
I think it's obvious that I'm no computer whiz...does this screenshot of my router settings give any clue to the solution to my problem? (which, simply stated, is that I want the wireless computers and devices to find my wireless network automatically)
