The reader may need a kernel module loaded. I have an old laptop with a built in Realtek PCIe card reader that requires the rtsx_pci_sdmmc module to be manually loaded.

If it is a PCIe card reader, it should have shown up in lspci even without the module loaded though.

Have you checked the BIOS settings to make sure it hasn’t been disabled there?

If the card reader is built in, it may show up as /dev/mmcblk0.

That is odd. I don’t seem to recall hearing about them launching the thousands of satellites that would be needed for that.

I wish HDMI would die. DisplayPort is the superior standard. HDMI is useless if GPU manufacturers are not allowed to release open source drivers for it.

The U6+ will nearly max out gigabit with a 160MHz channel. The U7 Pro can provide higher speeds, but keep in mind there is only room for a single 240MHz channel on 5GHz. You will need 2.5G ethernet to take advantage of the higher speeds.

Interference from any other WiFi networks within your channel will slow things down a lot though. That makes running with channels wider than 80MHz difficult if there are any other networks in range.

My access points are AC Lite and and U6 Lite. Those are discontinued though.

If I get more for inside, I would probably get the U6+. I am also thinking about getting one of the AC Mesh access points for outside. I’m not too worried about speed since anything that needs high speed is wired. I don’t have any neighbors, so I have all the bands to myself. If you are in an urban area, you should probably consider one with 6GHz support.

I use the Unifi access points. They work well and are fairly inexpensive. The management software can change settings on all of them at once, which is really handy if you have several.
