Not long ago we tested a wireless router from Trendnet called TEW-633GR. Its main traits were Gigabyte Ethernet ports and support for the IEEE 802.11n (draft N) standard. Today, we have got another router from Trendnet which offers the same functionality. The model we tested earlier features extended QoS settings whereas the TEW-672GR supports two frequency bands, 2.4 and 5GHz. To remind you, the 5GHz band is employed by the once-popular IEEE 802.11a standard.

We will see if the TEW-672GR differs greatly from the TEW-633GT in practical applications and what model is better.
