Dear all,

I'm using the latest versión of astroberry, working very well with VNC from a laptop and Hot spot Mode. But the problem is the wifi coverage, I need to work near the RPI4. I want to buy a wifi usb dongle with antenna that works well with RPI4, and I need that this dongle have drivers for raspbian and allow the Hot spot Mode, and if possible usb3.

I can't use a Ethernet cable....., i need WiFi yes or yes....

Please, any someone knows any dongle with these requeriments?

Thanks in advance,

Jose

Is your laptop 802.11ac or just 802.11b/g/n?

Dear gilesco,

My laptop have a, ac, b, g and n....

Thanks,

Jose

Try to set your laptop to just use bgn and not 5Ghz ac, range is bigger for bgn but speed is less, but OK for just VNC.

Pi4 already uses maximum strength allowed by regulatory protocols, but bgn is better for range if having to pass walls, thick heatsink etc .. ac is high speed, but short range.

Neither of these is faster or more stable than gigabit ethernet so dont expect anything better than when using a network cable, it is going to be worse.

I use the „BrosTrend 1200 MBit/s USB WLAN Stick Linux“ and I can highly recommend it (has 2 adjustable external antennas). I get superior signal strength and I can even connect to my 5G Wifi which is 2 walls away (94 % signal, perfect, no delays). See my post here RPi performance optimization . This stick works under Windows as well, of course.

Do you have AC power at your rig? Why not given powerline ethernet adapters a try? Close to ethernet speeds over your AC line. I use them and they are waaaaay better than wifi.

I have no problem with the internal 5GHz Wifi. Reach is actually farther than with anything else I have at home.

How far out do you have to connect? I have ~75% at 60 ft from the transmitter.

I limburg, this adapter allow Hot spot configuration?

I haven't tried hotspot yet. Maybe I have time today to check it.

Thanks limburg, this can Help me to make a decisión....

I just tried it out and the „BrosTrend 1200 MBit/s USB WLAN Stick Linux“ is capable of creating a 5G Wifi hotspot. I could create the hotspot and connect to it.

I didn't test 2.4G, but I'm sure this will work, too. But 5G is of course preferable because of the higher bandwidth.

CS, Bernd

Thanks limburg, I will buy then this dongle.

Thanks a lot for your time.
