My advice would be get a cable tester. Or see if you can loan some cable to test, with what your saying im almost sure you have a bad cable/connector/ethernet port somewhere.
And check if you synoligy supports gigabit networks and put in a gigabit swich. Then see if you wifi is still faster then you ethernet.
If you model is a 1xx, what happens when you disable https?
DSM version is?

Thats for wire also slow in my opinion, if have a "good" setup, you can get
the 100-115MB/s over gigabit lines.

Pff heres a lot to tell, basicly to much..
Most of the time bad cable.
And other pointers, latency, multple devices on the same channel,
( often 1 of 11 ) Wireless phones, microwave, etc all other 2.4Gz devices can interfeer with things.
I can get about 12-15Mb/s out of my wif ( 300N ) with tunning, without,
about 5-7MB/s ( test this within your lan )
Not alligned partitions on disk make things slow.
Lots of small files make things also slow.
Lots of files in 1 folder make things slow.
Samba 3.6.9 30-50MB/s is slow also.
Which synology, these are limited also.. like ..
Some of them have gigabit ethernet, but max speed of 100mbit ethernet.
This is often due cpu limitation.
In running simalar on a amd-E350 8Gb ram, kodi,
1ssd ( OS + websites and mysql )
2 3TB 5400 Rpm disk. Data pics mp3 backups etc.
Copy speed, in lan 115MB/s so the full gigabit.
IF i copy to a large file to an optimized partition. ( min 4MB blocks )
WHEN i copy the same file to my default partition,
it drops to about 60-80MB/s ( 4k blocks )
so if you want fast, you need to optimize.. ;-)
and get good cables.
