Wi-Fi modem/router fails to connect via wi-fi or RJ-45

 

>PROBLEM

The "ZTE MF253L LTE Wireless" Wi-Fi modem/router sometimes fails to accept Wi-Fi connections and comes with issues when using RJ-45.

A very odd defect that occurred after some years of usage.

>SOLUTION

Sometimes it is interesting to improve a modem/router that it is not that good than buying a new one.

ZTE MF253L has not a wide signal range but works well.

Instead of buying another modem/router, I decided to use a tp-link Wireless N 450Mbps router, model TL-WR940N, connected to the ZTE's internet output, using the RJ-45 cable.

The TL-WR940N model has a good signal range.

Now, I connect the notebooks direct to the tp-link router, instead of to the ZTE's, solving the connection issues. No more problems, at all.

Sometimes, when the ZTE's direct connection is not failing, it is possible to use it without the tp-link, but it is not an advantage at all, but remains as an alternative in case of a casual tp-link failure. 

When the provider's connection fails, the Window's wi-fi connections keeps the tp-link router active waiting and as soon as the connection is on again and nothing is changed on the notebooks connected to the tp-link.

This saves time when the failures are short.

If not, you may connect to the tp-link another modem/router using another number, a second option when you have it, without changing clients' configurations. If you have many machines, it helps a lot.

For some reason, sometimes Windows fails to reconnect the Wi-Fi, forcing to do a reboot.
This workaround also avoids this reboot.
