I am looking for router for home network.
Requirements:
- at least 100/1000 WAN/LAN port/s.
- VLAN support (using fiber GPON that uses VLAN, it would be set in bridge mode so router need support for that)
- WLAN 2.4 (5GHz optional) b/g/n
- Ability to set QoS (Don't know if sqm is there, but anything comparable would be good) - having bufferbloat problems that only restricting download/upload or anything like sqm options help.

All devices I have is one PC through ethernet, second through WiFi, smartphones, printer.
What would be good, not expensive router for my purposes?
