MiFi use both, Wlan and cellphone. You can decide.

University(field office) sends very strong signal in my direction, there is an agricultural project between use.
Without antenna, no signal. For LTE i use 2 different ones.

MiFi works like a booster.

I have a Rosewill wifi adapter that I use on desktop computers. They work well with Linux. I would be concerned about your distance from your neighbor's wifi affecting one of these adapters. Some of the Rosewill adapters do have antennas.
Thanks for that info KBD. It is good to know and perhaps others will receive benefits from this as well.
Have a GREAT day!

In general, built in network cards work much better than USB one because they have dual antennas going up into the screen area. I have come across laptops with poor wireless performance that has been due to one antenna being disconnected at the network card.

USB devices with external antenna are available, but in my experience are not always better. They also stick out a long way, and may end up damaging the USB port.

in general, the inbuilt WiFi card will start to fail on the Windows System firstly,
and then a little later on, on the Linux Dual_Boot System, as well.

at this point, using the inbuilt WiFi card gets very flaky,,
& so you start to browse the world of usb WiFi dongles.

personally, I've been using some old Netgear WG111v2 WiFi usb dongles,
but they are truly showing their age, now. :bawling:

the TP-Link Brand often comes up, especially on the eBay market & more so than on Amazon,,
and the later versions do give far better speeds, these days, and are also often natively detected by an Linux System,
especially at boot-up. :happy: so the TL-WN721n works well, and the TL-WN722n has 4dBi detachable antenna, is even better.

these things are dirt cheap on eBay these days & are a quick replacement for those failed inbuilt WiFi cards.

Be aware that a particular make/model of USB device may not always use the same chipset. Manufacturers swap around according to price and availability. This means that with two visually identical devices, one may work well, the other won't.

I have been bitten by this in the earlier days of Raspberry Pi, before they had wifi built in.

Thank you Pierre and Chris for your input.
So the chipsets that I would look for specifically aside from the atheros mentioned by Stevo or those at the wirelesshack.org?
I would not like to be bitten ;)

a particular make/model of USB device may not always use the same chipset,
- I've not come across that particular issue,
as I've always assumed that there was a different model, for each chipset.

so, I've better keep that one, in mind.

You can find them advertised as working with Linux. or the Raspberry Pi, and at least then you can return it if it doesn't work.

Looks like the first adapter you mentioned doesn't work on kernels above 3.9, so need to be careful which model # one uses. Some discussion about it on Amazon:

There is also a version 2.0 and 3.0 of the W722N out there that does not use the friendly Atheros chip--it's got some Realtek chip instead that I don't think has a driver in the kernel yet, I believe. So be very careful of what you're getting.

That is pretty confusing when they use different chips in these. Can be a pain for Linux.
