Gateway and Intel Wifi 5300

I noticed that lately when I tried to upgrade my wifi 4965 card to wifi 5300 my gateway M-6862 and P-6860FX both refused to load the device but the software was the same for both cards? Is there some kinda chipset or hardware limitation that prevents me from using a 5300 as it fits in the slot and both are intel? If I was to get one would I get a 5300 doesn't specify a make or model of laptop it fits on or what do I need to look for or is having a 5300 card not a possible outcome?

 

So has anyone done this switch or try to do this upgrade??? And what was their result??

 

I know most computers have to get their DST tables reset. The problem is the bios locks the resources of the old card into the DST table. With the P series you can turn the power on then before the DST table posts hold the power button to power off. This tels the system the DST post failed and next power up it will search hardware and reset the DST.

Other option is to pull all batteries including cmos and power then press and hold the power button 30 seconds. This should clear cmos and the DST..........

 

Really reset the DST is the akin to dayline saving time?? Would that really by just doing that make it accept a intel wifi 5300 even though a intel wifi 4965 was in the same location prior? I have to look and locate the cmos battery and give that a try.

 

I think I have my acronyms wrong, it is the SMBIOS and DMI table that needs resetting. Did this a few times before, DST is stuck in my head for some reason.............
