Just got a free pair of Askey AP5100W for my Singtel 1Gbps recontract (S$39.90 per month, SMS offer) and did some simple tests. I do not plan to use the units though as my existing setup (Asus RT-AX82U) is already working well.

My fIrst impressions.
1) Mobile app based setup is pretty simple. But you do need to crreate an Askey account in order to proceed (similar to TP-Link Deco).
2) Web UI default user name: admin; password: admin. It will ask you to change upon first login.
Features are pretty limited but better than the mobile app. Firmware version: Dual_SIG_1.01.107
3) Mobile app features are very limited.
4) Near range speed to the main node is decent (AC1750 rated=1300 Mbps 3x3 AC on 5GHz and 450Mbps on 2.4GHz), tested at 3m away, with Acer Windows 11 laptop and built-in Intel AX201 wifi adapter (2x2 AX/AC).
5) Wireless backhaul performance will be limited as this is a low end dual band mesh solution. The recommendation from the app is that the mesh node should be about 4-5m away and have a line of sight (no obstruction).
Test setup:
a) mesh node is about 4m away from main node
b) using wired connection to the mesh node using the above-mentioned laptop
Wireless connection to the mesh node will be even worse.
6) The wireless coverage is actually not bad, at lease better than my low end TP-Link Deco M4 mesh. For example, I can still get the mesh node to have green 5GHz Wifi LED in the more challenging place like the far corner of my master room or the kitchen. Of course the performance further reduced (say about 100Mbps from the wireless client).
7) Overall, this is a simple low end mesh solution which is probably good for small to medium sized household. It may be a good match with Singtel ONR users who do not require many features and just want better wireless coverage. For better performance, Ethernet backhaul is a must. The other use case is for the wireless connection of Singtel TV box -- you can still use your own mesh solution and then use the Askey (or Airties) just for the Singtel TV box.
