Card works with dual-band but fails to detect 5GHz in Windows 10.
so heres the story: i got an old dell m6500 laptop with a first gen i7 that i've been trying to upgrade the wifi in for the past month or so with little success. it came with a very basic 2.4ghz chip. i've had these machines before and know for a fact that these machines are capable of connecting to dual band/5ghz connections. in fact i have plenty other far older machines with even a pentium 4 that can see my 5ghz network, and they have been able to see the network for years. whenever i needed to connect to the 5ghz network on this machine, i have a comically large netgear wireless adapter usb thing that works well enough for downloading games and such. but its annoying. so i get myself an intel 7260an dual band chip, install it all fine with no issues. its one of the best wifi chips that will fit the old msata based connector of this machine, but i can still only connect to 2.4ghz wifi connections. i look in device manager and it for sure says that it's able to see wireless a/b/g/n. i change preferred network to 5.2ghz, but still i can only see 2.4ghz. oh well, maybe this computer is just too old for wireless ac. no big deal. so now i get a period correct intel centrino ultimate 6300 card, the best wifi card that this computer could come with from the factory. there's even a dedicated driver for it on the dell m6500 support page. awesome! i'll finally have 5ghz on the laptop without needing a usb thing! except no, i can still only see 2.4ghz in the detected wifi networks. running the netsh wlan show drivers command in cmd shows that it can in fact see 802.11a/b/g/n, it's just that windows 10 on this machine refuses to see my network despite literally everything else i own being able to see it and connect to it perfectly fine. i have tried performing a network reset in windows, but even after restarting with fresh network drivers, i can still only see 2.4ghz. worse now, not even my large netgear AC usb card will see 5ghz anymore! something is broken within windows. i'm willing to bet the intel 7260 card i got before would work perfectly fine if windows wasnt just trash. so, is there something i can do to the registry or something to allow the computer to see 5ghz when i absolutely do have a 5ghz capable network and 5ghz capable wireless card?
It's usually a driver problem, but the USB adapter also acting up raises doubts. In short, I tend to skip laptop vendor software and download them myself, particularly for Intel products.
now it loads the drivers Windows detects automatically after a network restart, but only showing 2.4GHz.
The Intel site indicates that no downloads are available for the Centrino 6300. https://downloadcenter.intel.com/product...-dual-band
I've faced the same issue when Windows removed drivers automatically versus installing them manually, especially with Intel systems. It's really frustrating. Have you checked the 7260 to check if those drivers are listed there? You're correct—if it was found, it should have installed properly, and I see others upgrading older Dell laptops using that card successfully.
I attempted to install the Intel drivers for the 7260, but it still couldn’t detect 5GHz. Around that time, Netgear also stopped recognizing 5GHz. Switching to the Centrino version resolved the issue, and now we’re seeing stable results. I’ve checked the BIOS for any settings that might interfere with Wi-Fi detection, but nothing stands out.
Verify whether 5G routers support WPA3 security. I've encountered similar concerns before. It might also rely on WPA2 or WPA3, which could affect older hardware.
It supports WPA/WPA2 encryption. It clearly functions, allowing even my Toshiba P25 with a Pentium 4 to connect to a 5GHz network.
The problem seems unclear. You mentioned using the N6300 but not seeing 5GHz wireless, yet a screenshot claims it is. Both 802.11A and N are 5GHz standards. The card only supports A, G, and N channels. Clarify whether the SSID broadcasting settings are combined or separate.
