First Sighting: mt7925 m.2 card (WiFi 7) (be careful with mt7927)

[morrownr]

There may be other cards with the mt7925 chipsets but this is the first one I have seen for sale:

https://zfishtek.com/index.php/product/mt7925-wireless-lan-card/

This is NOT a recommendation for the above product. What this message is about is to point out that the mt7925 chipsets are flowing to product makers. Cards almost always come to market before USB adapters. That is just the way it is so now that we see cards on the market, it probably means that adapters will be available soon. It is hard to say how soon but sometime this year is a reasonable expectation.

The driver for the mt7925 chipset has been in the Linux kernel since kernel 6.7.

Edit: Warning: Cards with the mt7927 chip are available as well but driver support for the mt7927 chip is not in the kernel yet.

If anyone gets a card with a mt7925 chipset, please give us a report.

I found a few on aliexpress and have one coming to play with.

Hi @ilikenwf

I found a few on aliexpress and have one coming to play with.

I am looking forward to your report. None of us out here in the real world know what kind of shape the mt7925 driver is in so any word would be appreciated.

Thanks

I'm just taking a $30 risk because my QCNFA765 keeps having persistent bugs even despite the fixes and I'm kinda tired of it...I'll take dysfunctional wifi 7 with functional 6E over dysfunctional 6E...

[ilikenwf]

...and I'm sure once this chip is perfected the price will 2x-4x.

[morrownr]

FYI: A user report indicates the mt7925 driver does not support the mt7927 chip that you may see. It would be wise to get cards with the mt7925 chip and not the mt7927 until we can sort this out.

[ilikenwf]

If that's the case I can attempt to help sort it or otherwise wait til it is - the linux wireless wiki suggests this chip is supported since kernel 6.7 though? I run Arch...so that's not an issue.

Come to think of it I'm not sure if this really counts as USB or not unless it's using the USB (saying bus here after feels redundant) through the E key slot on my board.

Here is the one I have coming:

Appears to be the 7925 so I spoke too soon. Haven't had my coffee yet.

[morrownr]

Haven't had my coffee yet.

I am working on my coffee. This is a coffee kind of day.

I am finding more info...see next msg.

MT7927

It appears that the only difference between the chips is that the mt7925 supports 160 Mhz channel width and the mt7927 supports 320 MHz channel width.

Indications are that the driver for the mt7927 chip has not been added to the kernel yet.

[ilikenwf]

I have not seen any mt7927s in my travels so far.

I have not seen any mt7827s in my travels so far.
