Need Advice for Wifi extender :D

Henry Do

im taking a vacation in Vietnam this June.

I just have a little question because my mom kept complaining about the wifi in our house right now. 

The problem is it cannot reach to the other side of the house and the 2 floors we have; which make me immediately think of the wifi extender

I have watched the video about how Linus travel down to Singapore(is it?) and fixed his aunt's wifi with the Ubiquiti Long Range.

Im thinking maybe i could do the same thing but im not sure it will work because there might be some problem which i haven't encounter (e.g. compatibility)

So i was wondering if you guys could help to find the most efficient and cheapest solution as possible (as im still a student).


Information about the house:

The house is all concrete 3 stories house (1 ground and 2 floors)

The router/modem is located at the 1st floor in the living room, each floor has 2 room

And the house roughly 1000 square feet (108 sqm)


The router/modem model is Dasan H640DW. I tried to search for this model but there is no luck. The Dasan H640GW might be the alternate for this model in north america


Thank you very much :)

Edit: Upon reading your question again I realize you are more or less looking to just upgrade your current setup and not replace it... @ItsTheDuckAgain made an excellent recommendation for that so if that's what you are looking for, stop reading this reply, if you are interested in upgrading it then read further.

I am not the local expert on this but I think that what you could do if you were feeling adventurous is you could get a used dell AIO (one with at least one or two PCIE expansion slots open), put some network cards in there (100mpbs is probably fine for your use case), and turn it into a homebrew router (the name of the os that you would want to put on there escapes me at the moment but I believe the name is in LTTs series on them failing at making a router [they screwed up here and there and it really isn't as hard as it seems in those videos]) You could also put A- a wireless card in there to broadcast to the downstairs and then get two (or one if you think you can get away with it) POE extenders/antennas for the upper two floors. (less expensive, though possibly more than one network for different floors)  B- you can not install a wireless card and instead opt for 2-3 unity hubs or a similar product for the different floors (more expensive, though more user-friendly). Again I am by no means an expert and I don't really know what the location looks like so take my advice with a grain of salt.

you want something like this I guess:


(got the same one at my parents and it works fine with the occasional wtf-why-did-it-stop-working-unplug-and-replug-thing done once a month.


got no idea what the other 2 guys above me are on about ....

Honestly the best advice for range extenders is to avoid them if at all possible. But if you must go that route at the very least try to find one that doesn't use the same radio for broadcast and backhaul. For example not the thing that @ItsTheDuckAgain linked, instead go with something that is a decent dual-band "extender" like one of these two:




Or alternatively have the extender use something other than WiFi for the backhaul. Run a cable or use a powerline kit. Because if you use a standard, low end range extender and connect it via WiFi on the same band as your main access point? You will get improved range but you'll significantly reduce reliability and performance.

Fools think they know everything, experts know they know nothing
