DNA & Moi has this issue (reported, hope they'll get it fixed), Elisa & Telia are free of this problem. Therefore your problem has a different cause.

Thank you, it's still a bit weird that MTU as low as 1277 is required for proper image loading on is.fi & hs.fi. I tried "mturoute -t" command (free tool) to the is.fi image server (after putting client MTU back to the default 1500) where fragmentation happens (if MTU is over 1277), and it says 1464: mturoute to…

Thank you for the information. I tried a USB wifi-adapter on my PC and connected to my smartphone hotspot, and the same result: MTU has to be set less than or equal to 1277 to avoid IP fragmentation on is.fi & hs.fi So it's not an issue with Zyxel LTE7490. If I had an ethernet internet connection, I could test whether the…

By editing the Backup/Restore file I tried lowering the MTU of my LTE7490 (thanks Bob_C for the tip), but it didn't help with my issue. Why is it needed to reduce client (Windows network adapter) MTU to 1277 or lower to avoid IP fragmentation on is.fi & hs.fi sites ? The issue source is hs-mediadelivery-fi.sanoma-sndp.fi &…

My ISP requires MTU 1400 and MSS 1360. When clicking Network Setting -> Broadband -> Broadband → Modify/Edit WAN Interface, the following screen is shown for a split second (suggesting LTE7490 MTU is 1500), but the final page is like in the first post. Could you fix this in the upcoming firmware version? Also, don't know…

Any update on this issue ?

Sure, it's V1.00(ABQY.6)C0

Thank you! Indeed, if you manually select B1,B3,B7,B20 under Band Management and then enter only B1 under Cellular Lock(LTE), it works! Just make sure your ISP's eNB isn't using energy saving feature by turning off one of the bands at night time…

Thank you for the info, I returned the Italian version and bought a proper generic LTE7490. Edit: Got it, and the firmware is now updated. Also SSH/Telnet checkboxes now work.
