The setup is:
- Routerboard RB912UAG+2HPnD
- two MMCX to female SMA 25cm
- two WiFi antennas 2dBi
- two GSM antennas 2G,3G,4G,GSM,LTE; 3dBi;
- miniPCIe GSM modem HP hs2340 HSPA+ MobileBroadband (says Ericsson F5521gw on the device itself)

The issue is that IMHO the WiFi signal is very week. The laptop standing right next to it has -40-50 dBm signal strength displayed on the registration table:
Code: Select all
[admin@RB-dsg-HCG081AERV3-B] /interface/wireless/registration-table> print
Columns: INTERFACE, MAC-ADDRESS, AP, SIGNAL-STRENGTH, TX-RATE, UPTIME
# INTERFACE MAC-ADDRESS AP SIGNAL-STRENGTH TX-RATE UPTIME
0 wlan1 DC:53:60:8A:5A:39 no -48dBm@HT40-4 150Mbps-40MHz/1S/SGI 1h26m50s
The very same laptop connected to the other device: Mikrotik LtAP Mini (with small built-in antennas) standing on the very same desk has much better signal:
Code: Select all
[admin@dsg-EB820F7A171A-B] /interface/wireless/registration-table> print
Columns: INTERFACE, MAC-ADDRESS, AP, SIGNAL-STRENGTH, TX-RATE, UPTIME
# INTERFACE MAC-ADDRESS AP SIGNAL-STRENGTH TX-RATE UPTIME
0 wlan1 DC:53:60:8A:5A:39 no -35dBm@1Mbps 1Mbps 2m59s
What is the reason for that? How can I improve the signal strenght in routerboard device?
