Before that you should consider the monopoly of TM in Broadband services. Most of the ISP are using TM Backbone. TM easily monopoly broadband services...

The backbone could have been developed and owned by government and should do nothing other than that. Shouldn't offer any services directly to consumer. This way, all the isp buy or rent backbone from government. And then, all isp is on the same ground. Consumer get to choose which is best.

Why do you need that sticker? Flash it yourselves. As easy as ABCDEFG. Unless you like to travel just to get that router.

I think he mean wifi. Can you define "in front"? And define "Unifi port 20 to 30meter"...

Since you say in front, I would assume it's the unit in front of your unit but now you added 20 to 30 meter. That's far more than the distance between two unit facing each other.
Anyway, if you want wifi, why don't you try with your wireless devices whether you can detect his wifi before asking to share. With my own experience, a condo usually have thick wall and also door. Like my unit, router inside the house, at the furthest end from the door(near balcony). As I get out from the house, made a turn and walk 10~20 steps, the signal is gone. And in my case, I'm using Tp-link TL-WR841ND. That is, with the door opened. If the door is closed, even worst... So assume that it's the unit opposite yours. If both door closed, I got no idea whether the signal can go through. At least in my case, the door is fireproof kinda thing, super thick and very dense(i feel that it's very dense ) Oh... Not to mention that in condo, wireless router performance will drop a lot due to intense interference of other wifi networks. In my location, i can detect 20 wireless access point when we got only 13 channels to use. Imagine that Not to say two routers cannot use same channel but they just won't work at full potential.

LAN cable may works but you need to get permission from management. Else they see the cable they cut it(I think I'll do so if I'm the management ) It won't look right to have a lan cable pulled across the corridor (just my thoughts).

That's why what he asked is quite... confusing. In front? Or 30~50meters away? That's the problem The easiet way still wifi gua... Repeater or super high gain wifi ap
