After turning on the device, I establish a wireless connection via my mobile phone or tablet. After a while, the connection drops. To reconnect, I manually select "reconnect." It cannot obtain a new IP address; it appears as "saved." To reconnect, I need to restart the device or the Wi-Fi.

The connection dropping and I can't reconnect.

It doesn't happen every day. If there was continuity, I would call it a technical malfunction. If it is not continuous, it does not constitute a technical malfunction.
 

No laptop, using wired connection on desktop PC too.
 

I think it's an issue with the rental period. I tried the maximum duration, it didn't work. I reset the device, but it didn't change anything. I thought one of the devices might have a virus, so I reset all the devices to factory settings. It's still happening.
 

This modem bothered me, so I got a VC220-G3u v2. I've been using another Tp-Link product for two days now and there are no problems.
 

I should mention that I don't speak any foreign languages, so I used a translation tool.
