anyone have try latest openwrt fw on v1 router with e398?

hi, im haing this problem..after i flash my mr3420v2 to huntsman fw, it detect n connect to my e398 but suddnely when i start to surf it diconnect n not reconnect at all..then i reset the router with press the reset button 30 seconds n when toe router is on it didnt recognize my e398...can anyone help me to solve this?look at the screenshot below..

is it because of hot??so weird..

so i just need to rest the router for at least 1 hour n turn it on n thats it?

dunnow whether its a bug or what..coz i try to flash back to factory fw also unsuccessful.

so u just flash from huntsman to blackwidow or flash to factory fw and flash to blackwidow? hmm..btw ur mr3420 is v1 or v2?

err.....abit confused on the step to flash to stock fw..how to to the second step?mind to share any video on how to do it? BTW im not able to use LAN cable to connect with the router...now using blackwidow..already try port in to WAN port n LAN port 1 but unable to connect on the user interface..only can connect thru wifi OPENWRT..

so just dload the firmware from the link goven n flash it thru blackwidow user interface?

already flash to stock firmware n now works on LAN n wifi..will try again flash to huntsman n see whether the weird thing happen again or not..

good idea..haha..need to run the test again before decide nak jual or not..

r u connecting ur e398 directly to the router usb port or using usb cable extension before connecting to the router?
