Base Station lost when DDR400 used

[Donchik]

Dear all,

I have been running a DWL-G520+ card for many months sucessfully in an old Soyo based AMD system.

Decided that it was too old in the tooth, and updraged to a Sempron 2400+ in a AsRock K7S8X R3.0 motherboard with 512Meg of DDR400 memory.

I set up the new system fine, and the D-Link card worked well. FYI I use WPA-PSK on my network, and the only other users in my area are weaker signals on WEP only.

During the configuration, I discovered that the AsRock board was failing to recognise the DDR400 memory, and running it as DDR333. I asked AsRock about this, and suprisingly quickly, they wrote back to advise where in the BIOS I should correct this. I set the system to use the DDR400 memory corectly, and the PC ran fine.

Fine that is except for the D-Link DWL-G520+ which stragely enough reported that only the WEP enabled base stations could be detected. I restarted my base station, but it was still not detected. As I had only changed the DDR settings in the BIOS, I reverted them to DDR333, and to my, and D-Link technical, the base station reappeared, and connected correctly.

None of the people at D-Link have seen this behaviour, and although I have updated all the firmware on the base station, the MoBo BIOS, and all the drivers, I am still unable to connect when the memory is set to run at optimum.

Has anybody out there see anything like this?

Can anybody suggest a solution?

All suggestions gratefully recieved.

Best regards

Donchik,

Could changing the memory bus speed also affect your PCI bus speed and prevent your adapter from working?

Assuming that your increased memory speed is not affecting the PCI bus speed or causing a data error of some sort, it might be the higher bus speed is creating a noise related issue.

Try getting another wifi device close to this machine and see if it suffers from packet loss or signal quality.

Try changing the individual BIOS settings you changed to get it to operate at 400MHz one at a time and see if the problem goes away.

Hi Conn,

Sounds like a possibility, but the card still functions, detecting other base stations in the area.

Don't think it would detect anything if the PCI bus was running over speed, but I will try an see if I can measure it.
