Well that is a spectacularly unimpressive bit of kit to be honest but 
you know what, it probably does the job for you just fine I'd imagine?

If you're using the 4 switch ports heavily to shunt data between 
multiple wired clients constantly then yeah,the 100Mbps limitation is 
truly terrible. If you're not doing that then it's not an issue for you.

That 300Mbps wifi limitation is also tragic but again: if it's not a 
bottleneck for you and you're not slinging large amounts of data around 
between different wireless clients in your house then well, that's not 
an issue for you either.

For once I'll try and be reasonable which is why I said you want to have 
a look at your usage model and do a cost/benefit analysis. If that 
router is holding you back and being frustrating, change it out (that 
offer of a free(?) Draytek was nice). Otherwise you're arguably just 
chucking away money on stuff that doesn't need replacing.

On the internal side of your network there are potentially more cost 
effective piecemeal ways of upgrading the individual parts that you 
_might_ want to sort out. A cheap 4 or 8 port dumb gigabit switch to 
handle wired traffic for example. You could heavily upgrade the wifi 
part by adding a modern AP - both of those could be done whilst leaving 
the router where it is. How fast is your internet connection though? I 
doubt it's faster than the router can handle but in these days of 
relatively cheap fibre to the premises connections it could even be the 
case that your DGN2200 is actually bottlenecking your pipe to the 
outside world.

Only you know all the pieces of the puzzle that go into making these 
purchasing decisions chief. It maybe that within reason you just like 
spending reasonable amounts on computer gadgets even if you technically 
speaking don't _need_ them - many of my friends fit into that category. 
At the other end of the scale there are people on the list running 10G 
ethernet or have 72" racks in the garage.

Back to your original issue of upgrading your wifi adapter though so as 
to avoid going straight down the rabbit hole. I also must confess that I 
was perhaps a bit too cavalier in my approach to modern USB wifi support 
on Linux as it is a bit of a minefield especially if you're not cool 
with digging through endless forums and experimenting with compiling 
semi-random drivers from github (I am of course, and forget that many 
people just don't want to deal with that crap). You can do a lot worse 
than start here:

https://www.amazon.co.uk/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=linux+usb+wifi+ac

Read the comments and reviews with a specific eye for other buyers 
reports on getting it running on the same distro as you - there are 
usually a surprising amount of Ubuntu/Mint/whatever users who've bought 
the units, done the hard work for you and explained how they did it. 
Those comments are gold and can often really help you narrow down your 
search.

Just keep in mind that as things stand for you currently your DGN2200 
tops out at 802.11n and doesn't do 5GHz: it's maximum is 802.11n @ 
300Mbps in the 2.4Ghz spectrum. That's ok(-ish) but it's your hard limit 
no matter what fancy 5GHz MIMO ac adapter you buy.

Make sense?

Cheers
