Hello all, i just bought the mudi, configuring it worked alright. Im seeing now that the 4G speeds are much slower then what im experiencing with the same SIM card on my iPhone. Using [Speedtest.net](http://Speedtest.net) (configured to use the same server in Frankfurt): iPhone: ~72 Mbps down and ~5 mbps up Mudi: ~14 mbps down and ~6 mbps up I saw a old [post](https://forum.gl-inet.com/t/mudi-gl-e750-w-ep06-e-slow-4g-lte-speed/19518/16) about the slow speeds. They have forced Mudi into 4G, i cant figure out how to do so, or if its even neccesary. Getting into SSH with putty is no Problem, pasting their Command (AT+QCFG="nwscanmode",3,1) doesnt work. ![image](https://forum-static.gl-inet.com/original/3X/1/f/1fe507d23a7be7dde770aa5fc6590831c70d4e3a.png) Mudi: ![image](https://forum-static.gl-inet.com/original/3X/c/6/c6cb52ec4c4587483a1c39babf958952bc314ba2.png) What could be the problem and solution? ---

You can insert the card into your phone and dial ```auto *3001#12345#* ``` to see the band ![image](https://forum-static.gl-inet.com/original/3X/6/4/64016169d53af04c316bea3a66baa3d10bcf3417.png) Try locking the same band here ---

It just outputs an error. With and without the "gl\_modem" part ![image](https://forum-static.gl-inet.com/original/3X/c/5/c5aa93dbc1e689c77028347d7e30143d2ada3863.png) ---

I changed the TTL, no improvements. Does anyone have some more tips? Performance is quite terrible.. ---

Can I see the rest of this picture? Can you send me the results of these commands ```auto AT+QCFG="nwscanmode" AT+QMBNCFG="list" AT+QGMR ``` ---

Of course, here you go: AT+QCFG="nwscanmode",3,1 ![image](https://forum-static.gl-inet.com/original/3X/d/1/d15ee781a09aa1de152236e3e4043db7d1c4d23a.png) AT+QCFG="nwscanmode" ![image](https://forum-static.gl-inet.com/original/3X/a/d/ad3b6b6380df0a04921a3786e4cd56fa17dd8e5b.png) AT+QMBNCFG="list" ![image](https://forum-static.gl-inet.com/original/3X/5/b/5b8fe3f93efe54eccb8e52e0ed497b247df8589c.png) AT+QGMR ![image](https://forum-static.gl-inet.com/original/3X/c/3/c3648bb358579830a0ce7538b9e50b7287b8c86c.png) ---
