Planex plans to release the GW-USMicronN Wireless-N adapter next month. The unit allows you to make a painless upgrade to Wireless-N, providing you have the appropriate router. It’s possibly the smallest 802.11n USB adapter to date, 1/6th the size of the D-Link it is pictured with.

Early testing has indicated that it’s competitive with other models and features the same security measures to boot. The adapter will cost $30 and arrives in the US in December.

TRENDnet has just announced its new 300Mbps Wireless Easy-N-Upgrader device to get you in on the high speeds that draft-N is delivering.

But instead of having to buy another router (as I did), you can upgrade your existing wired or wireless router to 802.11n.

TRENDnet says it will cost 15-20% less than a standalone wireless n router. No word yet on availability.
