Re: Does size of antenna matter?

Plus in Mikrotik parlance, does number of chains = number of antennae = spatial streams? This is true : number of chains = number of antennae However, it does not mean that it equals the number of spatial streams. With Nstreme you can setup full duplex communications where one antenna sends and one...

Re: Wi-Fi 2.4G limit 30mpbs

If there is interference, wider channel may decrease throughput. WiFi is CSMA/CA, it means it will stop transmitting if it detects another transmission at just 3 dB above the noise floor. If the noise floor is at -100 dBm and you get a signal from your neighbor at -97 dBm, your equipment will stop t...

Is it okay to have this on the bridge - mainly so you can see what IP the access point/switch is using?
I think it's better that the AP does not have any IP during troubleshooting, to make sure it's not doing routing and that it's behaving as a simple switch.

Re: hAP ax3 ruining USB dongles

I have not seen other reports of similar issues with USB port of the Mikrotik Ax3, maybe you were just (very) unlucky?
Or you suspect that your particular device has a defect?
How to tell? It's still under warranty but I need some solid proof and testing is expensive.

hAP ax3 ruining USB dongles

I wanted to log stuff to a USB dongle, so I tried a cheap 8 GB stick and after a while it got ruined, won't work anymore even in other computers. Then I tried another cheap 8 GB stick of another brand, same story. Then I tried my expensive 128 GB transcend memory (https://www.transcend-info.com/prod...

Re: Antenna showdown with my Nano VNA

I conducted some RSSI measurements with the antennas I have. The Yagi antenna has already been discarded. Distance: 1.2 meters between the Access Point (AP) and the phone, with a clear line of sight. The biggest antenna is 0.16 meters so we are well further than the calculated far field of 1 meter (...

Antenna showdown with my Nano VNA

I just got the Nano VNA SAA v2 and started testing all the antennas I had. First in line, the Asus one, the one that comes with the PCE-AX58BT. Shines the brightest on channel 11.

Re: hAP ax3 + Realtek RTL8821CE 802.11ac = bad wifi speed[SOLVED]

P.S.: Check this: https://forums.linuxmint.com/viewtopic.php?t=394684 That did it. Using driver rtl8821ce instead of rtw88_8821ce. I got 186 Mbps download and 67 Mbps upload. Still not the 300 Mbps that my other devices are getting but it's acceptable. Why the problem presents itself only with Mikr...

Re: hAP ax3 + Realtek RTL8821CE 802.11ac = bad wifi speed[SOLVED]

WiFi 6, lightweight, touchscreen, works well with linux, very long battery life, and cheap enough that I don't worry of it being stolen or damaged. Sounds like a mid-range Chromebook. Mine manages to push 180 Mbit/sec to the Internet through the ax³ from a few rooms away. It's a 2021 model, so one ...

One of the reasons I suggested using an /export command instead of /print is that it suppresses sensitive info like your WiFi password by default. I've edited that out of your postings above, but you can't count on us moderators to backstop you like that every single time. Other than local details ...

Re: hAP ax3 + Realtek RTL8821CE 802.11ac = bad wifi speed[SOLVED]

I tried using 2.4 GHz Unlike ax, ac isn't defined for both 2.4 and 5GHz. You would have fallen down to "n" at best. If it fell down to "g" instead, that would explain your speeds. Assuming both radios are using the same SSID, I'd try turning on FT mode on them both, giving the l...

VLAN is a L2 concept, it has nothing to do with layer 3 from the OSI model. Your laptop is on the normal (untagged) broadcast domain But you set your router on the vlan 1 broadcast domain(thus packets are tagged from ether1) The devices are in 2 different broadcast domains(L2) this is why they cann...
