Ok, embora isso não resolva o problema em geral, especificamente no meu caso, meu colega informou que há um sistema de prevenção contra intrusões sem fio (WIPS) no prédio - ele bloqueia pontos de acesso sem registro não registrados que aparecem dentro do alcance.
Como solucionar problemas de desconexão Wi-Fi freqüente do roteador MiFi?
1
Recentemente,atualizeideummodemUSBHUAWEIE153paraum Roteador WiFi móvel E583C .
O dispositivo concede a meus outros dispositivos acesso à Internet por wi-fi perfeitamente, até que eu me localize no meu escritório atual. Entre cinco e trinta minutos, meus computadores dependentes perderão a conexão Wi-Fi.
A tentativa de reconectar falhará. Quaisquer novos dispositivos que tentem registrar sua rede wifi também <<> falharão . Levaria muito tempo até que ele pudesse "se recuperar" e os adaptadores wifi pudessem pegar a conexão e recuperar o acesso à Internet. Eu sou forçado a conectar o cabo USB para manter uma conexão de rede com fio.
Meu colega tem um modelo de mifi similar, o HUAWEI E5830, que ela experimenta exatamente o mesmo problema - multa externa, desconexão garantida no escritório.
O primeiro palpite é que existem muitos outros pontos de acesso Wi-Fi no edifício, por isso tentei mudar os canais de transmissão 1, 6, 11 e até 13, mas nenhum teve melhores resultados. Ao expandir os registros de diagnóstico de rede do Windows, há cerca de 19 redes na área, portanto, acredito que a interferência seja tão grande que meu dispositivo mifi não pode competir. Mesmo se eu conectar a antena estendida.
Abaixo está o log de diagnóstico, que eu não consigo identificar adequadamente o que posso fazer para solucionar ainda mais e possivelmente resolver o problema nesta área de escritório?Windows Network Diagnostics Publisher details

If you're connected to a hotspot or domain network, contact the network administrator. Otherwise: 1. Unplug or turn off the device. 2. After all the lights on the device are off, wait at least 10 seconds. 3. Turn the device back on or plug it back into the power outlet. To restart a router or access point that has a built-in battery, press and quickly release the Reset button.
