I have gone thru all the recommended steps in troubleshooting why my e7 MFD won't pair with my Quantum E70344 radar scanner. The system was working perfectly until I took it down to install an AIS250 AIS receiver. The AIS250 works fine, but now the Quantum and e7 won't pair. The Quantum's SSID and passcode have been checked at least 4 times, and as I said worked fine before. Wifi Analyzer shows the e7 SSID transmitting when I turn the MFD on. When I supply power to the Quantum and tell the e7 to pair with it, after a minute or so, the e7's SSID signal on Wifi Analyzer disappears, and the Quantum's appears (Quantum_xxxxxxx, "xxxxxxx" being the Quantum's serial number). Both signals are on the same channel, with a signal strength of approximately -30dbM. Wifi Analyzer shows no other SSID's in the area on the same channel with any strength greater than -70. On my laptop, I can connect to both the Quantum SSID, and the e7's SSID. The e7 has the most recent firmware version (19.03 as I recall). The Quantum is only 4 months old, and so I would think has most recent firmware. As I said, all worked fine previous to hooking up the AIS250, which connects to the e7 via wires, so I would expect that would have no effect on wifi issues. Raymarine technical support (2nd level--1st level was baffled) says to be sure I have 12v to the Quantum, and if so, send the unit in for warranty work. It would appear to me if Wifi Analyzer is showing the Quantum's SSID, I surely must have 12v to the unit, and it is transmitting OK. If I did send it in to Raymarine, I would expect I would need to send both the Quantum and the e7 in as the issue is the pairing between them. As everything was working perfectly before installing the AIS250, I have got to believe it is not a hardware problem, but more likely a firmware or some SSID/Passcode/signal strength/channel number problem that possibly a local Raymarine dealer/installer might be able to help with. But all of those are OK. Any ideas?
