Just got a new PW4 on Prime day: 8gb, SO, wifi, 5.10.1.3.

I wanted to avoid 5.12 so decided to JB and upgrade to 5.11.2. (My old PW4 is 5.10.3. JB and everything...)

Downloaded everything from the latest snapshots.
Skipped wifi config and registration, and proceeded with JB.

*** I did not put it in airplane mode ***

JB went fine. Upgraded to 5.11.2. Installed MRPI, KUAL, usbnet, gawk, librariansync, python, linkss and a bunch of other extensions. Basically, set up this PW4 identically to my old PW4.

Copied my dictionaries and a collection of books. So now the 2 PW4 are identical in content. The main diff is that the old PW4 had all packages from snapshots as of early March.

Generated collections from folders. Setup SS to cover mode. Rebooted. Did a quick check and noticed that the PW4 was sluggish on all touches and page turns. Also, the message that SS Cover mode did not process any covers yet. Left the PW4 on wall charger and went to dinner.

Came back a couple of hours later and see that nothing improved. Cover mode is still giving message. Page turns are slow. And indexing only processed less than 10 books per hour. No matter what books I opened (mobi, azw3, User Guide) could not get the cover mode to work, and still sluggish.

Deleted all books except 1 and User Guide. Let it index 1 book. No change.

Uninstalled Python and linkss from current snapshot and reinstalled Python and linkss from the March snapshot. No change: no cover mode and sluggish.

Knowing that occasionally Amazon updates impact device performance, I thought that maybe 5.10.1.3 to 5.11.2 update did something. So I ran the hotfix, reset the device, reinstalled and recopied everything. No change: no cover mode and sluggish, and very slow indexing.

At this point I knew that I need help from the guru, and decided to prepare a set of logs that NiLuJe will request: ran ;DM, collected MRPI log, ran SS in verbose mode. Before asking for help I started reading the logs. There were no problems with any packages. However, there was a barrage of errors in System log that it's trying to connect to network and failing everything (sync, store, metadata, authentication, blah-blah-blah). But I never even connected to wifi!

*** So I put the device into airplane mode! ***

Suddenly, there is no sluggishness, indexing is working as expected, cover mode is working!

So even if you never configure wifi and never connect to anything, airplane mode is absolutely necessary.
