I have a brand new TalkTalk Wi-Fi Hub, the FAST5364 3.00 which has been updated to Software Version SG4K10001E00t, GUI Version 3.7.2. Whilst the view of the Logs accessible under the Maintenance tab now includes additional navigation buttons allowing access to the top and bottom of the log with one click, there seems to have been a change in the sort sequence attempting to place new entries on the first page (instead of the last). However the pre-existing entries have not been resorted so I now have a hybrid with page one starting at 31.03.2019 23:59:52, page 2 starting at 31.03.2019 23:54:51, page 3 starting at 31.03.2019 23:49:51, etc, and the last page starting at 01.04.2019 00:02:52, last-1 starting at 01.04.2019 00:12:52, last-2 starting at 01.04.2019 00:21:52, last-3 starting at 01.04.2019 00:24:22, last-4 starting at 01.04.2019 00:34:22. The cross-over point is most of the way down page 38 / 1170. Dammed odd.
I just checked the logs again and now the list seems correct, with the latest entries appearing on the first page. Device uptime reads 5h39m40s suggesting it rebooted itself early this morning. Device details are unchanged.
