Data copy speeds from my NAS to the Desktop PC

Remember I paid a lot of money for a router last month? Was it worth it, or did it only make a large hole in my pocket?

Well, I’ll let the following screenshot answer that question.


This is a screenshot of a file copy dialog of Windows 10, which was taken while copying a ~4GB file from the NAS server to my Desktop PC via 802.11ac. It is copying at 70MBps+ speed. This is a massive improvement over 7MBps odd I was getting with the old router.

The Wi-Fi module in the Desktop PC, which is the onboard Wi-Fi chip that comes with the Z97i Plus motherboard, is rated at only 867Mbps. The router is the Asus DSL-AC68U running, not a recent firmware (not the latest, as I could not find time to update the firmware and test it today, after finding out there was newer firmware out.)

The distance is only about 3m between the antenna on the PC and the router though. But that is OK as I do not have any other powerful device farther than that. Also, the NAS server is connected to the router via Ethernet using two gigabit connections and load balanced using teaming in Windows Server 2012 R2. However, the hard drives in the NAS server are not using RAID to improve performance. So teaming the LAN ports probably does not make any difference.

Anyways, I am quite happy with the performance.

Now only if I could find some Crysis 3 local servers. There used to be local servers, but the popularity of Crysis 3 has gone down so much that almost none of them are operating. Although I was able to find a server with <100ms ping once, with everyone else having 200ms+ ping. I felt like god for a moment.

Marshmallows are no good!

So, no, exchanging phones with my wife DID NOT fix the GPS issue.

Today I had to drive to a shop to get some furniture about 25km away from my apartment, and the GPS acted up again. This was on the Nexus 5 my wife was using earlier. The phone was running Marshmallow 6.0.1. It was freshly installed couple of days ago.

The GPS problem persisted with Google Maps as well as Nokia Here maps. The issue occurred several times throughout the 50km or so total distance.

Thankfully I did not have to do a U-turn and correct the route. If I had to do that, I would have been super pissed because we had to make it to the shop before 5pm. And it was 3:40pm when we started heading for the shop.

Guess I have two options.

  • Switch back to Kitkat and enjoy a properly working phone, but look like a caveman.
  • Buy a new phone, making a hole bigger than AUD700.

Whether or not I go for the 2nd option needs very careful consideration. For the time being, I am back with Kitkat. *sigh*

What if I switch phones with my wife?

After writing that last post, I got a great idea.

What if my wife's phone doesn't have the GPS problem my phone has/had? If her phone functions properly, I can simply switch the phones because she doesn't drive the car yet. We both have the same phone so she won't miss a thing.

Ideally, I should have tested her phone a few days to see if it was working properly, but I was impatient. I wanted to switch first and then test. Then at least I would be able to use Marshmallow again. The feeling of being able to use the latest OS makes me happy, even if it is slow.

I factory reset both phones and flashed the latest version of Marshmallow available on Google to both phones. I swapped the SIM cards and the phone cases.

I restored the applications from the corresponding latest backups to both phones. That meant installing a lot of applications than what Marshmallow was used to running on my phone, because my final backup was from KitKat and I had installed a lot of app on it because it never slowed down like its successors.

This immediately brought back the sluggishness I was so used to on my phone. I used the phone the whole day yesterday and it eventually became somewhat usable. Either the indexes/caches we constructed to make things faster or my body got used to the sluggishness. Or it can be both.

What about the GPS issue? Is it better on this phone?

Yesterday I had to drive for about 30 minutes (I had to visit a house in Mulgrave to check some furniture which was advertised on Gumtree) and I found the location to update without a hiccup on Google Maps. Does this mean the problem is fixed? No, because it is definitely too early to draw any conclusions just yet but the initial results are at least positive. I think it needs at least a whole week of testing but I don't drive much, so a week of good performance is still not a good indicator. We shall see. I'm sure you'll hear more about this topic soon.
