Re: What is wrong with nv2?

About year ago after I got dissapointed by 802.11ac support from mikrotik I decided to use other producer equipment. The other one that gave me so much enjoyment to work with.

Re: Balance connected customers between AP - s

You can limit max number of stations which can connect to an AP, together with limiting the minimum signal should be enough to provide reasonable WiFi service. Keep in mind that you want to limit signal from client to AP, as per your post I would understand that you want to limit the signal strength...

Take the percentage increase of physical layer throughput. You see the same increase in real performance if your signal is strong enough. MT has to do some work to make that happen with nv2. With plain 802.11 you see this gain. Take a look here. http://www.winncom.com/images/stories/GoNet_WP_Things...

Re: Using a second Mikrotik as a wired Wifi repeater

Use VLANs to make separate bridges between the CRS and 2011.

Create Bridges for each virtual AP, add the virtual AP interface and vlan interface to each bridge and you are done :)

Re: HotSpot different pool for trial users

But how would the DHCP server recognize if you are paid or trial user when assigning the IP address? I guess this will not work, you define the address pool in the Servers tab, not profile. And its impossible to have 2 hotspot servers working independetly on one interface.

Re: How many SXT clients on 1 Basebox with dualpole sector &

I apply QoS just in L3 In another router (RB1100) I apply QoS and PCQ, limiting total bandwidth the AP can manage (I usually set it to 20mb/down and 5mb/up Regards So your AP can only handle 25Mb? Dont you use 802.11n MIMO and NV2? Mine can do 70Mb without any problem, not with 70 clients of course...

Re: The right choice in P2P polarization

I had one link mistakenly reversed polarization on each side (one side was CH0 V / CH1 H and the other side CH0 H / CH1 V) and there was no difference in the link at all, although I would guess it should be same on both sides of the link.

Re: RB433 & 802.11N high speed wifi to utilize broadband 100

In the wifi adapter (Intel centrino N-6205) settings on my laptop there are advance settings for channel width but only for 802.11 n . There is no mention for channel width for b/g?? From what I can see on the net 40Mhz is only for n? I am confused. Hmm I have to say I am not exactly sure about thi...

Re: 2 Ptp links and I lose half the bandwidth

I have seen similar behaviour long time ago when using routerboards with more than 1 wireless card, therefore started to build x86 with 2 or 3 cards max. Usually the root cause of this was shared IRQ but that was before NV2 was introduced. Could you check if your cards uses different IRQ? Did you tr...

Inox thank you on your suggestion! lucky79 thank you also very much on your suggestions! I tried to switch to 40MHz turbo in RB433 but then none of my laptops (windows 7, win XP) nor mobile phones (symbian, android) do not see my wifi network? Youre welcome This is weird, sometimes the wireless car...

I have RB433 with R52 802.11 b/g wifi card for my home LAN. My ISP gives me new high speed broadband for my home. Till now I had 4/0,5 Mbps adsl link, and now I have 100/20 Mbps. Till now ma R52 was enough but with this new 100/20 Mbps speed my R52 now is a bottleneck for my wifi laptops that have ...

Re: wireless AC can't find Noise Floor Threshold

Noise floor is a measurement of the ambient RF noise as seen by your wifi interface. It is not configurable, it is a read only value. It is however used in conjunction with signal strength to calculate the SNR value. Hi Skillful, sorry but I dont agree, with N cards you could set the noise floor ma...

we can't fix problems in existing old version :) please upgrade back to v6.20 where you did not have these issues Hi Normis, nobody want you to fix existing old version :D the thing is many people including me do see better wireless (NV2) performance in 5.26 than 6.20 as Tonymobile mentioned one of...

Re: Manual noise floor threshold in AC products

Actually after doing some more tests it seems that NV2 protocol is lowering the CCQ and not noise as I thought.... if I use 802.11 I can get 99-100% CCQ but when switch to NV2 it drops to 60-90%... Throughput seems to be a bit better with 802.11 but the latency is too high with some load on the link...

Manual noise floor threshold in AC products

Hello guys, anyone noticed the noise floor threshold disappeared from the AC products? I have started using SXTAC and Netmetal 5, both not having this advanced option... used this quite a lot in noisy environments mostly for short links where it helped a lot achieving 99% CCQ. When upgraded these hi...
