How to force a Wi-Fi USB adapter on a Synology DiskStation to use 5GHz ac from 2.4GHz

Useful if your SSIDs are identical for 5GHz and 2.4GHz. Having your SSIDs setup like this seems to confuse Synology DSM, and for me it would always connect to the 2.4GHz network.

I had this particular issue where my TP-Link T4U ac wifi adapter for my Synology kept dropping down to using the 2.4GHz network, which slows it down dramatically.

To fix this, here’s what I did. Your mileage may vary, and you may end up disconnecting your Synology from the network, so make sure you have another way of getting to it (such as Ethernet) before proceeding with any of this!

SSH to the DiskStation, login as admin.

sudo -s to root account (same password as admin account)

Make a copy of your existing wifi config file inside /usr/syno/etc/wifi/

For me, I did:

Edit the original file with vi. If you don’t know how to use vi, do a web searhc (it’s not hard, but not easy either).

What you need to do is remove reference to the 2.4ghz network, which you can identify from the bssid, which is the MAC address of your router’s 2.4ghz radio. Once you’re done, the file should just contain details for the bssid that’s your 5ghz network. On my router, the MAC address for the 5GHz network was one hex number higher than the 2.4GHz network.

Next, make a copy of the wpa_supplicant file in /usr/syno/etc. For me, this was called: wpa_supplicant.conf.wlan0

Now edit the file, and change the bssid (which will be the 2.4ghz bssid MAC address) to the bssid MAC address of the 5ghz network.

Reboot the Synology diskstation, and when it comes back, it should be on the 5GHz network.

I kinda figured you’d need to remove half the chassis. Makes me appreciate just how accessible the HDDs are in most Dell laptops 🙂

How to force VMware to generate a new MAC address for a virtual machine

How to force VMware to regenerate a MAC address for a virtual machine (or guest OS).

  1. Shut down the Guest OS.
  2. Open up the .vmx file.
  3. Delete the following lines (that begin with…):

  4. Boot up the Guest OS again, and it should generate new details in the vmx file (I’d check afterwards to be doubly sure).


The most common scenario for wanting to do this is if you’ve used a “template” Guest OS and copied it to multiple PCs, but accidentally clicked “I moved this Virtual Machine” rather than “I copied this Virtual Machine” when first booting the Guest OS in something like VMware Player.

If you tell VMware that the Guest OS was copied, it automatically generates new UUID info and MAC addresses. If you tell VMware that you moved the Guest OS, all unique identifiers are left alone (including the MAC address). By performing the steps above, you can get VMware to generate you some new, unique identifiers, and stop weirdness on your network 😉
