Currently I am on TM Unifi RM129 plan, with 100Mbps.
Current wifi router is DLINK DIR-850L (Black short cylinder shape)
Double storey terrace - 20' x 60'
Wifi router locate at ground floor TV cabinet
My usage as below:
1. Stock trading
2. Normal browsing (Facebook / Taobao / Email)
3. Working at home (VPN / Cloud storage)
4. FM Radio Streaming
5. Youtube Music Streaming
6. TV Box HD Video Streaming (Occasionally)
7. 2 persons living in the premise
Current internet speed: Happy, no issue, satisfy
Current wifi router: Not happy, sometimes disconnect without reasons.
Sometime I share screen using laptop on my Smart TV:
1. Laptop on 5Ghz wifi frequency
2. Smart TV on Wired LAN
<Question 1>
Contract has just ended and planning the next steps:
1. To continue existing plan without renewing contract?
2. To renew contract with existing plan (maybe to get free wifi router)?
3. To downgrade to RM89 plan, with 30Mbps?
<Question 2>Previously I was using 2.4Ghz wifi signal to screen sharing, very laggy and keep DC.
Then I changed to 5Ghz, it works greater, but I feel like a bit of delay. Especially when I moving my mouse pointer, very hard to select object precisely on TV due to pointer movement delay.
Disconnection of share screen happen occasionally, maybe 5%~10% of chance.
Current wifi router DLINK DIR-850L is running its 5Ghz at AC1200, if I upgrade to any router that greater than AC1200, let say AC1750, do you think it will solve this problem?<Question 3>My 2nd floor wifi signal very poor even using 2.4Ghz signal. However, I rectified it by adding additional WiFI extender (DLink DAP-1330).
Current wifi router DLINK DIR-850L is running its 2.4Ghz at 300Mpbs. If I upgrade any router that greater than 300Mbps, let say 450Mbps or 600Mbps, is the wireless range will be improve, or still remain?Considering I do not wish to use wireless extender due to energy saving.
(In this case, wireless range is the key concern, speed not important)
<Question 4>If I upgrade router myself, I will prefer ASUS, but which model is suit my usage but not overkill?
a) RT-AC86U
b) RT-AC66U
c) RT-AC68U
d) any other model?
Up to you on what speed you want, but I recommend 100Mbps at least if you have a lot of devices and doing all of that you mentioned. Don't bother getting free router from TM. TM router SUCKS.
The AC numbers does not matter if you want coverage. Don't look at the numbers. You need a good reliable router. It won't solve your issue if the AC numbers are extremely high, but the router is a bad one.
Again, don't look at the AC numbers. By the way, extender does not use a lot of energy. If you want consistent coverage, get WiFi mesh system, or if you can't afford it, get a good router.
If you want something good and reliable, and is quite new, get the Asus RT-AC86U. If you don't mind something older, get the Asus RT-AC68U. If you want to save more money, get the Asus RT-AC1300UHP.
Looks like a rebranded TP-Link Archer VR1200V.
