I would like to ask what is the best mode for a network running AC access points but a mix of N and AC (arm) CPEs: NV2, nstreme or 802.11 ? Let me describe my environment and how it came about to help you understand the stage I'm at and my current dilemma. I have a wisp environment where I started ...

networkfudge

Yes and yes

networkfudge

This is not AC mode, AC mode will reach around 240Mbps on 40MHz :P yeee single TCP stream 240 Mbit from 40 Mhz :D Mby in lab. Impossible: 802.11ac MCS9 = 200Mbps is highest possible connection rate for 40Mhz channel, one stream. You are on dual stream. You can't beat the standard... The guy never s...

Hi all,
Someone has tested more scenarios with ARM, 5ghz AC, ROS 6.44 with NV2 or 802.11?

networkfudge

just a question; now for ptp link wich is better between nv2 and 802.11n? nv2 was designed to optimise performance of point to multipoint networks. Usually vanilla 802.11 is faster in ptp however in cases where there is interference nv2 can perform better than 802.11. When setting up ptp links I al...

Thank you!

But yeah, finetuning your P2MP is the hot word here. And one new AP or frequency shift from a competitor can throw all your hours of finetuning overboard ..... :? Yes its a never ending battle in p2mp. You are very lucky you can get good results on 80mhz. I don't have 80mhz of clean, contiguous spe...

So far, 802.11ac on ARM devices is the best choice. My opinion. My APs are mostly netmetal (mipsbe AC) and my CPEs are typically LHG XL (mipsbe N) I use NV2 with dynamic downlink of 70/80% and 20Mhz channels To be fair to Mikrotik, since the couple of changes they made in 2018 our bandwidth per sec...

A sector with 15 clients a/n/40mhz and the one I've tested is old single core .ac. Under each picture you can find the protocol used. Sadly in 802.11 is not stable and clients gets a lot of disconnections so I'm sticking with nstreme. The conclusion is Mikrotik have lost speed in any protocol, a lo...

Default-config script on shipped version doesn't set up the router fully, it applies IP address 192.168.88.1 to ETHER1 and that's about it. Use mac-winbox to connect and setup to your liking.

networkfudge

If this is a PTMP setup I would opt for the 19dbi sector antenna. Unless you have an extreme lack of space, or if you are setting up a close-range network (you wouldn't be asking about max distance if that were the case), then it's worth going for the much useful extra 4db of the mANT 19 paired with...

networkfudge

From your rates I'm guessing you are on 20mhz but you need more if you want higher throughput. This new XXXX option I'm guessing it tries to automatically set the best control frequency, but in any case it's a new development and I haven't found documentation for it, so try manually setting the requ...

I am sure the xtra $$ is good value, just asking besides the 256MiB, what is the impetus to move up to the board? Better hardware.

networkfudge

Hahahaha you are very funny. You want me to pay $40 more bucks for 256MiB? and lose a USB port in the process (only a shitty usb.2.0 port so I guess its not much of a loss).

As others have pointed your signal levels are terribly low for such short distances. This means that your links are misaligned, not to mention also potentially riddled with LOS, fresnel, intererference and frequency problems.

No need for the forward accept rule. It is difficult to understand what you are trying to accomplish. I assume you are trying to open TCP/445 from the outside through the firewall.

If these routers have an lcd screen and if its not locked and you have physical access, you can maybe restore a previously saved configuration via the lcd screen.

Setup your wap ac as an AP not a router, you can probably accomplish this from quickset but I've never used it. Add ether1 and WLANs to a bridge, add a DHCP client to the bridge for management and you're done, same L2 network as your archer

networkfudge

Narrowing the scan-list on the CPE will reproduce what you are describing, on the AP it shouldn't have any effect whatsoever.

After a reboot we have noticed a much faster clients wireless registration when scan list it reduced, if it's set to Default or in the above example it will take longer.

networkfudge

Are you certain about this? I had always thought that scan-list has no effect in AP modes? [/quote] Just curious why you have set the scan-list=5000-6000 as this results in the AP to listen to all frequencies between 5-6GHz - we when using 20Mhz channels set our AP's -/+ 20Mhz above and below the AP...

If you have enough addresses to assign to all customers then the cleanest solution would be to set up a pppoe server. Then each customer will have their own ip and if you use a radius server you will have good stats/accounting

I would argue that one must always test radio links with single tcp stream. Testing whether your tcp connection can build up and withstand its speed is the one true benchmark when it comes to testing your layer 1 (radio link in our case). Say for example you get 70meg with 1 connection tcp traffic ...

Here's what I would do A. Go to base level 1. Upgrade ROS to anything newer than 6.42rc46 (significant improvement in nv2) 2. Set a 20Mhz channel 3.

I can confirm a consistent 2x increase in bandwidth on 1 N and 3 AC basestations after this update. 20mhz channel, nv2 period size auto, dynamic downlink 70% Bandwidth increase observed before upgrading routerboard firmware on basestation and without touching any of the CPE devices.

I had tested the original RB-750UP a couple of years ago but found it somewhat unreliable, especially if more than three devices were powered on by the router. Also it was prone to malfunction (POE out on some ports died on two occassions), but my cables were not shielded in my test setup so that co...

networkfudge

Just focus on not having crappy stations. Bad signal = lower modulations = lower rates = lower overall AP throughput. One bad CPE at basic rate 6mbit will cripple your entire setup. The goal here is not to have bad signals. Try not to have lower than -65dbm when possible.

POE-out port on ac lite is 0.5a so max power draw is 12w. Dynadish max power draw is 9w, factored in with a bit of voltage drop (due to utp cable length/quality) to get to the dynadish then this power should be just about adequate. But then you have to add this 12w max power draw on the poe out port...

AC offers the possibility of higher throughput due to denser modulations and wider bands, it has nothing to do with radio tx power and rx sensitivity.These parameters will not automatically be better because the chip is AC.
