What Could Be The Problem ? Uplink Interference ? Or What ? Dirty Channel ? [spectrum] [E-Align] [MCS] [Status] [Uptime] ?

Ive written about this before, and youre right. Do not listen to those telling you tonreduce channel width or lock mcs to highest rate - this is the worst thing to do. What you’ve done is exactly right, you need to lock the mcs rate to the lowest rate that has packets passing, accept the lowest rate…

What problems are you actually experiencing with the link? From everything you’ve shown, this link doesn’t actually look too bad. There’s really only two things you can do to reduce retransmissions, latency/jitter… reduce channel width and/or find a less noisy channel. You might also be able to get…

Changing channel and channel width can only be done by ISP so I have limited options. I am experiencing high ping and ping spikes while gaming more especially from 15:00 to 18:00 the downlink locks itself to DS MCS 2 - QPSK 3/4 during that period. The Link Quality Flactuates Every 5 Seconds And D…

Then you will need to get your ISP involved, or find a new ISP.

Seems Like The Only Way To Stop This Is Limiting Downlink To DS MCS 5 - 64-QAM 2/3 And Uplink To DS MCS 3 - 16-QAM 1/2 That Way Jitter Is Around 5ms And Ping Is 18ms In Most Tests

Exactly. This thing of locking mcs to the one which passes the most packets doesn’t work. Better to keep reducing mcs till 99% or 100% of packets pass at chosen mcs while also monitoring retransmissions and capacity drop packets.

[image] PtP 550 and ePtP PTP You can reduce jitter on your link by dropping maximum mcs on the offending radio. Look at the performance stats, find where the mcs is jumping around and set it at the lower value. You will see latency flatten off. I run dual 80's…

That is precisely what i said :laughing:

A different brand has an adjustment for Exactly that: “Pessimistic, Normal, Optimistic” still adjust automatically as conditions change, but just erring on the side of caution If that works the better in your situation

Yeah, like how in ePTP mode it gives you a low latency, balanced, and high throughput options.

2026 and we’re still having to lock in max MCS rates. Ridiculous. Needs a more pessimistic MCS rate set in software based on retransmit rates. We don’t have time mess around setting max MCS rates on thousands of radios
