I'm pretty much at my wits end... Have made numerous calls to D-Link tech support, and while they've been helpful they have yet to resolve my problem. I'll give as much info here as I can, although it will be lengthy.
In my office I have a D-Link DGL-4300 Wireless Router - in the livingroom a D-Link DWL-G520 Wireless NIC. Both PCs are running Win 98SE and are fully patched (as far as O/S). The office PC has no trouble with internet access and is connected with a wire to the router, then to a cable modem. I have dutifully installed my wireless NIC per instructions (driver first, then shut down and install card in PCI slot). No matter what I do I cannot get these two machines to talk to each other. There is less than 30 feet between the wireless devices and practically a direct sight line between the antennas.
I am not getting any flashing of the blue wireless indicator light on the router. While on my cordless phone with D-Link tech support today, I reset the router and while this was occuring I could hear clicks in the phone indicative of the router putting out a wireless signal but it eventually stops and the wireless status lamp goes solid (no blinking) once the reset is complete. I remember that when I first installed the router I was noticing some slight interference with my PC speakers. I feel this was an indication of a wireless signal being broadcast, but I haven't noticed this for some time now.
On the router I've had the SSID created along with an encryption key which was dutifully entered into the Air-Link Wireless Configuration Utility. As far as I could tell all configuration items on the wireless NIC machine were properly set but the PC will not pick up any signal from the router. Once changes are made refreshing produces no results. The router has been reset (taken back to default configuration) and channels changed from 6 to channel 11 on both machines - nothing. D-Link even sent me a new NIC opining that the original one I purchased through Buy.com was defective. That changed nothing. I have even unplugged my 2.4GHz cordless phone to negate the possibility of interference. Nothing. I've gone through so many router configuration screens, D-Link FAQs, Knowledge Base articles and User Manual text that my head is spinning. It has been more than a month since I got this equipment and I have at times stayed away from the problem only because I needed a break. If only I could put a hard wire between these two machines... but unfortunately it's impossible in my home.
I'll probably be calling D-Link support back again today (we had a session earlier today) to continue to troubleshoot this issue, but I'm really wearing down. It's not like I haven't tried to take care of this problem myself before asking for help. I've tried setting up MAC filters (doesn't work because the router can't see the WNIC), I've tried every configuration tweak I could find on the WNIC machine and the router configuration
but am never able to detect a signal.
I don't know if any settings in Windows that relate to networking have to be addressed. It should be noted that previously these two machines were successfully networked for file and internet sharing on a hard wire through a LinkSys BESFR41 router. The machines were eventually disconnected and packed away as I was moving. Now they're in my new home and I simply tried to re-establish the network, but wirelessly. The previous network was running under ZoneAlarm Pro on both machines. Now I have ZA Pro disabled on both PCs and the router machine has a trial version of Outpost Pro installed. There is currently no firewall software running on the WNIC machine.
Is there any hope...?
