Model: CPE510  
Hardware Version:
Firmware Version:

I'm using CPE 510 for 1.5kms distance. both antennas are 50feet above. it has a decent speed (for me) for a home use of 3-12mbps out of 100mbps internet subscription. 
I'm asking for your help if it is possible to improve even further. 

I'm have 10mhz channel width since both device couldn't connect each other with higher channel. 10mhz has better bandwith compare with 5mhz but has poor latency especially on client side. but both configurations have time out. I'm thinking to shorten my POE since it has 30meters , (i'm not sure but i think i have read in this forum that longer POE especially cat5 affects the consistency of the product. 

all advice are appreciated. thank you.

ping from client side using ap side.for more details about my network please let me know what you need

@NAJIV, I got best result at 802.11n-only mode, 40 MHz, distance set to »Auto«, MAXtream disabled, carefully aligned antennas and fresnel zone clearance. Note that 40 MHz is guaranteed to not overlap in EU, if you're in another country your mileage may vary and you might try with 20 MHz.

 

As for high latency you can't do anything over a shared medium such as WiFi, but timeouts should not happen (and no, it has nothing to do with the cable except it's a faulty cable - unreliable contacts or such).

 

With 17m above you mean over ground? Or is your antenna pole 17m/50ft long? If the latter, timeouts could probably be caused by slightly movements of the CPEs in the wind.

@R1D2 

thank you for your reply.

50 feet from the ground, actually the 50ft-pole is attached to the ground.most houses from from the line of sight has 20-40 feet. 

I will try turning off the maxtream, and get back here for the result.

also I'm wondering why i got poor latency pinging AP using the client side compare to using AP and pinging client side. 


I want also to thank you in your post regarding with 4 pcs of 510 and using load balancer. I will do the same once I bring back the money I spent for 2 510s. having free internet in home, it will take 5 months for the investment.

wow, that's what I got with maxtream off. 

i want to try your settings wiht 40mhz but I'm afraid losing my remote connection to client side (i'm on my office right now) and no one to bring back to 10mhz to resume the channel width. 

thank you very much r1, i read most of your post here in the forum and believe me, you helped not only me but most, members here. thank you.

i tried different settings, 10mhz, 802.11a/n works best for me. with disabled maxtream.

now I don't understand why i'm experiencing huge difference in terms latency in both CPE.


pinging client side using AP gives me a decent result of 1-60ms
while pinging AP using client side, AP replies with 100sh latency. 

have you experience this too? is it normal to have a such difference? or do i need to improve my atenna as far as I understand, I need to improve my AP since this is the side that throws poor latency. is that right? please enlighten me. TIA.

100ms or 100times? (Sorry, English is not my native language.)

 

I'm not sure what happens here, since ping involves both, sending and receiving. So, echo replies should need the same time or nearly the same.

 

As for the antenna mast it is a very large height. In my country, antenna masts >4m (~ 12ft) must be anchored, >10m (~ 30ft) must be anchored multiple times. Only exception are fat masts with trapezoidal structure. How do you avoid bending for a 17m (~ 50ft) mast?

@R1D2  anchor too, i have read from other forum it is because my ap is located on city, considering crowded frequency and obstacles while my client is located on clear area 

 

100ms

That was my first thought, too, but the the ICMP reply to a ping from the opposite CPE should also show this time.

 

Anyway, 100ms is not a huge delay in respect to 60ms and it can indeed be cause by asymmetric interferences or load on the CPE.

Pinging from Client Side

 

I have a faulty router on my client side and that's the culprit. I can't believe i missed such details. after a restart , it's working fine at least but not as stable as should be since I'm still getting 1000sh ms from PC to Router via Wifi itself. 

in summary: your maxtream-disabled advice really did  a great job. I can't achive such good latency until i turned it off.
actually in one of their youtube video discussing about CPE installation, i also noticed that it is also turned off. I'm confuse but because of their marketing features and etc of how they boast such feature, it didn't come in my mind to turn it off. as a I understand TP link product, that Maxtream give CPE a distinct function for long range wireless services over TP link EAPs. 

again thank you very much R1

@NAJIV, you'r welcome. Glad it now works better.

 

As for MAXtream it is very useful for PtMP links as shown in the following diagram. It greatly helps to avoid the Hidden Node Problem, but at the expense of a (somewhat) lower throughput. For a PtP link it's just not needed as it adds protocol overhead not useful at all.

@R1D2  thanks again for another insert, 

 

 

In my next project im opting for 6.5km distance but with much clear libe of sight. Im planning to use cpe 610 hoping to get close latency from my prevuous installation
