If you have a local LAN, ping is probably not the best thing to determine if it's slow or not - you'll almost certainly get <10ms responses.

I would check your network hardware, your switch/hub in particular, also, check the Speed/Duplex settings on each of the devices to make sure it matches what the switch can do, some cheaper switches do not negotiate speed and/or duplex correctly and end up mismatching.

If you're using a hub, get a switch!

I updated the firmware on the router as well as checked cables - all normal.

Less packets dropped the better. 5% or less is not desirable but it you should be able to function fine though on an internal small network you should not be seeing this at all. VPN will be affected by dropped packets though
