Here is a problem.
I have 2 BaseBox2 devices (both of them worked fine about 2 years).
Now, I’m testing it with my “Ericsson F3507g Mobile Broadband Minicard Composite Device”.
Installed modem, modem works fine.
When i tested my first BaseBox2, some time later, i have noticed, that level of WiFi is very low. And I can’t make it better, even if i update RouterOS, or make default configuration.
I’m testing my BaseBox2 on table, distance is around 2 meters, and on that distance i recieve very bad signal at full power (no_country) and can’t find any wifi, if set russia|regulatory-domain.
After that I took second BaseBox2 with working WiFi, and tested it again with modem. Devices worked fine for about 1 week. After that, I have noticed, that level of WiFi is very low again.
Result is - I can not see WiFi of BaseBox2 if i use /interface wireless set frequency-mode=regulatory-domain (russia, max 20), but when i witch it to manual-txpower, than i see WiFi, but signal is very poor.
I used standard power source (from box) and RBPOE, RBGPOE. I used both devices with standard antennas mounted on it.
Update to “6.40.5” - no result.
Now, when i power on both BB2:
*one round part is very hot, cant touch it (see picture)
*radiatior on other side is very hot too (after 5-10 min of work)
I powered on BaseBox2 only with connected wifi antennas.
When i remove modem, wifi not coming back.
My questions:
- What could go wrong? Why both devices fails with the same result?
- Does powering on for a short period of time is very dangerous for WiFi controllers?
