某局点使用MSR810-LM 做4G拨号上网,但是一直拨号失败。
1.检查设备配置,现场使用的就是电信卡,所以配置没有问题

2.检查拨号口的状态,SIM正常识别,信号强度也达标。

3.查看拨号日志,最后连接到了2G,怀疑SIM卡的4G功能没有开通。

4.将SIM卡在手机上测试,确实只有2G信号,4G没有开通。
MSR路由器不同型号支持不同方式的4G拨号上网,当4G拨号失败时,可以做以下排查:
1.确认4G卡状态是否良好;
2.确认4G卡是否设置了PIN码;
3.确认4G卡是否能够被识别;
4.信号强度是否足够;
5.确认4G卡是否注册成功;
6.APN配置是否正确;
7.路由器4G相关配置是否正确。
8.可以将SIM在手机上做测试。
