Anyone know what the latest firmware for the M1100 fixs?

JSchnee21: Bear in mind that both MicW and I are running our M1's without battery, on upgraded mains chargers (higher power than the supplied 2A charger). At least I think that's what MicW said. When I did the test yesterday to check simultaneous downloads on both WiFi bands, I wasn't running solely on the battery. Have you tried doing the same test using an upgraded charger instead of running on battery?

Regarding the various firmware releases in different countries and for different carriers, although the version numbering system may appear to be sequential / chronological, it's possible and even likely that there are different branches in the numbering. So a version issued to Telstra customers may appear to be more advanced numerically than one issued to AT&T customers but the included features may be a mishmass of whatever happens to suit or be compatible with that carrier. Why on earth would a contiguous firmware development jump from 10.x.x.x to 12.x.x.x (TeeJay74 in Finland)?

That's why I asked Netgear to demystify their firmware version numbering and to make update/changelog histories available to the public (see my link in message 2 above). For example, does the version numbering contain an indication of a specific branch, i.e. an identifier for a specific carrier? Or does Netgear maintain a private list that documents which version is for which carrier? How many of us in different countries with different carriers are on identical firmware version numbers? It seems to me that we're all on different numbers. Perhaps we should all contribute to a list that documents the following:

Country - Carrier - Firmware Version - Build Date - Install Date.

It may be necessary to hold this list somewhere other than this community page because threads scroll lower as more are added, unless we can encourage a Netgear moderator to make the list "sticky" - this may be difficult if their intention is to keep us guessing.
