DWR-921 OpenWrt - able to select individual 4G Bands?


Thinking of puting OpenWRT on my DWR-921 but only if it gives me the benefits of being able to select an individual 4G band. The reason is that band 7 2600MHz (B7) – Optus has the most bandwidth available and is the fastest. However I don't think the DWR-921 selects this band very often so I want to force the modem to use that band only.
