I’m having issues with my network, if anyone can take a look at the design layout and may be able to help with below issues.
Bandwidth tests between routers
R2-R1 Download speed 100M + (R2 - R1 is over wireless)
R4-R2 Download speed 100M + (R4 - R2 is over wireless)
R4-R1 Fluctuates between 30MB to 50MB
PPPoE terminations are on routers close to clients, no PPPoE server on R2
Client on R4 CPE connected to PPPoE. Bandwidth tests to R1 show 20M but on speedtest.net show different results, up and down to 10MB.
This is the issue - make some tests using MK TCP 1 (TCP connection count) connection test (or iperf or other single TCP throughput test). What protocol is selected at the wireless links R1-R2,R2-R4 ? (NV2 is not good for p2p).
R1 - R2: 802.11 ac wireless
R2 - R4 is set to NV2 as I was creating self interference on the R1 - R2 link
NV2 is all I can use on R2 - R4 as nstreme drops to many times due to interference.
The link is passing over a small town and is picking up alot of access points in the 5ghz band.
I changed out the R4 ptp 2 link to an rf element dishes instead of a QRTac this helped a bit
R1-R2
5805
5Ghz only AC
5805/20-Ceee/ac(33dBm)
Tx / Rx Signal Strenght -29/-28 dBm
distance is set to dynamic but the link is 1KM in distance
TX fluctuates up and down between 50 to 80% and the RX is fairly consistent between 80% to 90% there is always traffic going through the link
Signal to noise is 80 dB
R1-R4
5785
5785/20/an(33dBm)
74/70 % CCQ
7 km link distance
NV2 wireless protocol
Signal to noise is 63 dB
Tx/Rx signal strength -45/-45 dBm
\
CCQ at R1-R2 during TCP test 74/52 % it fluctuates between 50 / 90 both Tx / Rx bandwidth test shows 130Mbps to 150Mbps in direction receive
CCQ at R2-R4 during TCP test 78/73 % is fluctuates between 70 / 80 both Tx / Rx bandwidth test shows 38Mbps to 40Mbps in direction receive
CCQ at R4-R1 TCP during TCP test 95/69 % it fluctuates between 60 / 90 both Tx / Rx bandwidth test shows 38Mbps to 40Mbps in direction receive
Note: If I bandwidth test from the clients CPE, it hits 20mb download on the cpe back to R1 but when I go to the clients house and do a download test on speedtest.net it peaks between 9 - 10Mb.
I left MTU blank on the pppoe server.
The client cpe I have it set it to 1480
The client is having the traffic shaping done on R4 and I see very few packet drops in the queue tab, its set to wireless default queue type.
The connection to the client cpe is a qrt ac 802.11 license 4 in ap bridge
5745/20-Ceee/ac(33dBm)
-53/-56 dBm
CCQ 92/87 %
Noise Floor -106 dBm
Signal to noise 51 dB
5785/20/an(33dBm) is R2-R4 PTP link
5745/20-Ceee/ac(33dBm) is an AP on R4 facing opposite direction to the PTP R2-R4 link
R4 AP was set to AUTO frequency and it set itself to 5745/20-Ceee/ac(33dBm)
The AP is running routeros-mipsbe-6.42.11, do I need to change installation is set to “Outdoor” and nearest client to furthest client distance on the AP with is around 9KM
Most 802.11 devices will only detect C channel as occupied while other channels might get described as “noisy” if they happen to be utilized during channel scan.
BTW, what’s front-to-back ratio of both antennae? I’m afraid that sum of both is not much higher than 30dB, which quite less than path loss of a typical PtP link.
R2 side UltraDishTM TP 550 with MikroTik RouterBOARD RB922UAGS 5HPacD 802.11ac 866Mbps
R4 side UltraDishTM TP 400 with MikroTik RouterBOARD RB911G 5HPacD 802.11ac 866Mbps
AP on R4 is QRT AC L4
Detect Radar is causing a lot of issues with frequency selection
