Yeah, you'll need a power source. The PoE injector can be anywhere along the cable. If the distance is quite far, you can put it somewhere in the middle.

You can calculate the voltage drop. Simplistically speaking, it's V=IR. What we learn in Sek Men. The R will depend on the quality, material, AWG and length of the conductor (the cable). Probably easier to do it experimentally. If you're using the same box of Cat6A for your house, just wire up a 10m length and test the resistance or voltage drop. That'll give you pretty good idea of what you can expect from your cables.

But for me, I just plugin 12V and see what comes out the other end. Not enough, plugin 24V. Most devices which accepts passive PoE (also known as fake PoE by another well informed forumer here) will be able to handle a range of voltages. Example: my Mikrotik AP accepts anything from 8-30V. UBNT is probably the same.

And then there's 802.3 af/at PoE. This one I never use before.

Please don't use cheap cat 6 cable or cat 5 which is not full copper.

Got heh fake poe i thought fake cables

Even though short distance 5 meter also cannot power up ap

Thanks for the input. Sigh couldn’t get Cat6a, the sub contractor only have Legrand Cat6.


It’s Legrand Cat6, I googled seems to be pure copper type. The sub contractor charging me RM 200 per cable (long or short also same 😅). Only advantage is the cables are being installed when the house is built, so I no need hack when receive my keys later.

power lost in the cable have to take into consideration
awg22 23 cable resistant is around 6Ohms/100meter

power=i^2*r

let said power consumption is 1.5a
power loss over 100 meter cable is 13.5watt(13.5watt juz wasted and convert to heat...not good )



v/r=9 volt drop over 100 meter


he need a 24v 2a power supply

As long as the cable doesn't melt, should be OK lah. When I calc voltage drop for PoE, I use the length of the cable x 2. My Dintek cables not so good, no way I'll get 9v drop over 100 meters.

Ask him to do a proper conduit and trunking, it might happen 1 day you might need to replace your cables..
My conduit wires all broken when i try to pull.. now have to go by surface mounting..

Just got myself a HAP AC.. hope it's not the wrong choice.. Might want to add another Cap ac on my 3rd floor

hAP AC as your main router? What speed is your UniFi? Afraid to say that the hAP AC routing performance is relatively weak.

I did a test here with the hAP AC. https://forum.lowyat.net/index.php?showtopi...post&p=90330495

Not a comprehensive test but it didn’t give me a very impression of the hAP AC. I’m currently using one as an AP only. WiFi also so-so lah. But then again Mikrotik’s WiFi is always just so-so only.

yeah the HAP AC seems a little disappointing.. using it as my main router... 500Mbps unifi..

For Rm500+ I expect maybe better performances

can you suggest the best mikrotik router for TIME 1Gbps?

hAP AC2 will be good enough. It handles UniFi 800Mbps with room to spare. And TIME's internet doesn't use VLANs which means less CPU needed.

RB4011 for sure OK but 3x more expensive.

Hi need your all advised , i try to proposal wireless solution to my customer which run cafe business recently and TM was upgrade the 800m plan for them. My customer wish to expand their wireless coverage and with some bandwidth limitation by IP control within 1 hours valid for the guest wifi. any idea bro which model can do it ? I know mikrotik wifi signal is quite so so only , so can i get another good router work as AP and then can link to miktrotik hotspot captival portal as well ?

Bro i can do this for you got complete solutions

pm detail for contact further.

i dont have hAP AC2, just hAP. I have an EdgeRouter-X though, does it better than hAP in terms on performance? I know the functionalities is win by MikroTik.

ERX is same, more or less, as RB750Gr3. Same Mediatek CPU, Both are better than hAP AC in terms of routing speed.

I was using the RB750Gr3 before changing to a hAP AC2. The RB750Gr3 is OK but you gotta make sure bridge port hw_offload is enabled and fasttrack is operational. The main prob I faced was the 1Gbps link from the switch to the CPU. The hAP AC2 has a 2Gbps link.

A few tests I did on RB750Gr3 on Turbo500.

Marginal for 500Mbps. If you're doing more with the router, definitely not good enough. If default config then no probs for 800Mbps.

hAP AC2 on Turbo 800. Much better.

Hi all sifu, i like to get a Mikrotik router for hobby and home use.

My house devices up 15, mix with wired and wifi, unifi 100mbps.

Current router is Asus AC55uhp, plan to set this router as AP

Can recommend a suitable Mikrotik router ?

Depend on ur budget hap ac2 or rb4011 with wifi

I agree with MX510, go for the hAP AC2. Whether you use its wifi or not, it's a really awesome router.

Also the RB750Gr3, no wifi, router only, about RM50 cheaper.

thanks for recommendation.

How about wireless performance ? house size single story, 30x80

Any buyer for CCR 1009? I'm thinking to revamp my setup and also get the RB4001 and some other stuff.
