No no, wifi is not faster than ethernet, much slower. Ethernet speed I 
have seen at 60MB/s. Obviously that is Gbit.

I have no issues with wired. The Wifi is a TP-Link 1043 router (old 
model) and should be fine (it was very popular). I am hard pressed to 
try other wifi devices (can only use my phone as a second device) (but 
it has a cifs download thing; it didn't go higher than about 1MB per 
second though when I tried (I think).

I never used "N" networking before, I had my router configured at G 
previously. Clearly the phone became much faster when I switched it to N 
exclusively. Internet download speeds (from the computer) also became 
faster I think; it is then that I saw the 5MB/s max. There were several 
concurrent downloads and they added to more than 5MB/s.

I guess that is the NAS then. It is a DS112j, it may not have more CPU 
power for it....

The harddisk itself will probably read about 100MB/s.

The Synology has nothing to do with the wifi. That is just the router.

The wifi client is actually a Level One device that is pretty shoddy. It 
is a WAP-6113 or something. There can be no issue with the cable. There 
are no other devices communicating unless they are from around (I live 
in a dense area). There is no microwave, etc. I may have to check ...

There was another wifi access point but it shouldn't have been 
communicating in any way.

Currently the speed starts out at about 4MB/s max and then goes down to 
2.5 MB/s after a few minutes, mirroring the behaviour I have seen 
before, but still okay.

How come tunneling makes it faster? Doesn't that add encryption?

Not relevant really here.

Yes the NAS is going to be CPU limited. However that shouldn't be the 
case for Wifi as it has nothing to do with the Synology. I have no 
problems with the 60MB/s max.

Some people have 500MB/s SSD disks.

I am still trying to solve my 3MB/s.

Are these NTFS clusters or something else?

Is it inode size or something?

I was just talking about Wifi really ;-). But thanks for the pointers on 
regular wired ethernet too.

I have no comparison and I don't really know anyone, so.... that helps
