I got 4 Pines (2GGB version).
After I successfully created 3 Sandisk 16GB (uhs-1 uU3) android sd cards with the latest build, I started testing them
All 4 booted flawlessly within seconds. However, only 2 of them can browse the internet and connect to Play Store.
They do get an IP assigned while date and time get also synchronized, nevertheless it is like if they are not connected to the internet at all! I'm unable to browse any site (not even Google) and Play Store displays connection error.
After I saw this behaviour by 2 of my Pines, I decided I will run all 4 under the same circumstances (same 20awg usb lead, Anker 2.4A PSU, connected to my Gigabit switch with a specific 50cm Cat7 Ethernet cable, same microSD)
The same 2 that initially had problems, persisted the same behaviour (got IP and date/time but no internet)
I subsequently tried the Wifi/BT module with those 2 and successfully connected to the internet.
At this point, I started believing there is a problem with their Gigabit chip. It was then that I thought I had to try another OS. I burnt an image with xbuntu (latest longsleep's version). The 2 specific Pines booted within seconds and connected to the internet successfully. I browsed the internet with Pidora and they were quite responsive.
However, when I tried a speed test (speedtest.net) I got only 0.5/5 and 5/5 respectively while my usual speeds are 74/5.
That said, upload speed doesn't seem to be affected. Download is hammered though!
I have seen some users recommending one should push the Gigabit network to 100Mbit in order to achieve decent download speeds. Despite I don't know how am I supposed to be doing this, I am willing to try.
The question is why 2 of my Pines perform excellent within my Gigabt network while the other 2 don't?
Is there a possibility those 2 being faulty? With just 30 days of warranty I don't have much time to experiment or wait for updates. If there is no solution soon I'll have to send those 2 back as they clearly underperform under pretty much all conditions.
ANY RECOMMENDATIONS BEFORE I PRONOUNCE THEM FAULTY?
By the way the board exceeded my expectations. I was expecting something MUCH WORSE judging by all these posts lately with dozens of different problems users have faced as of now. However, latest Android works really smooth and fast for me with no crashes whatsoever. I can see smooth 1080p YouTube videos through YouTube app and browsing the internet is flawless. Ubuntu worked also quite well during the few minutes I tested it. I suggest all those who face any kind of problems to use a good quality SD card, burn a rooted DD image of the size of their card with Win32diskimager, use short 20AWG charging cables and a known-branded PSU rated over 2A. Provided you do all these, I doubt you will have problems or instability issues.
Good job guys. I can see some serious potential on the Pine. This thing can only get better from now on!
So, it seems that you just confirmed that the gigabit ethernet issues half of people are having is a hardware defect. If you just tested them in the same conditions with the same image, it is unlikely that the problem is in the software. Now, how to get a replacement?
