Wireless/Cellular
6.2.1
What if the wireless connection is not stable after associating
with an AP under wireless client mode?
•
In addition, you can start “ Site Survey ” to check the signal strength. If it is weak or unstable
(The smaller the number is, the weaker the signal strength is.), please join other available AP
for better connection.
•
If you install the directional antenna for point to point/multi-point connection, adjust the antenna
and tune the signal strength/performance by Antenna Alignment Tool again. After antenna
alignment, the data rate test can help you check the current performance.
•
In Wireless client mode, type the connected AP’ MAC address to fix the AP for your client. It
avoid your wireless client not to connect other AP.
6.2.2
What if the wireless connection performance is not good, how to
improve it?
•
Once the signal strength RSSI is always under -65dbm in long distance transmission, it is
suggest you to change antenna’s direction or replace antenna with higher gain.
•
Check the “ Space in meter ” setting in “Wireless Advance Setting” . Correct the distance can
help improve the transmission quality.
•
If the distance between the wireless client and target AP is short, but, the antenna gain is very
high. Reduce the RF power is also an option.
6.2.3
What if the LTE connection is not stable or poor performance
after associating with the base station?
•
Please check the signal strength first. Once the signal strength is poor, the connection may be
unstable. Even the connection is established, the performance is poor as well.
•
You can move the device closed to the window or install external antenna outside the
box/room/factory.
•
If the distance between the Gateway and base station is far, the high gain antenna is an option
to improve the transmission quality.
•
Check whether the antenna supports LTE band or not? Normally, the outlook of the LTE
