The TEW-655BR3G/A is a good product that needs a few tweaks and additions to be a great product. We were happy with the performance we saw when we connected to any PC using a Wireless N card or adapter. However, the performance when we attached our iPad was more than a little off. This could be another WiFi issue that is rearing its head in the iPad or a compatibility issue between the WiFi on the iPad and the TEW-655BR3G. We also were a little disappointed that we had such a hard time with the Sierra Wireless Compass that we have. Granted, it was an easy fix, but now we need to carry around an extension cable to use the TEW-655BR3G in the way it is primarily intended.
There was also an interesting added benefit. Some 3G adapters do not play well with VPN connections. The reason for this is because the 3G connection is not much more than a TAP adapter that emulates an Ethernet device to send layer 2 packets (for internet and other TCP/IP traffic). Most VPN connections are also TAP adapters; this means that when you fire up your VPN connection you kill the 3G connection.
With the TEW-655BR3G/A handling the 3G connection this was not an issue at all. I was able to connect using a few different VPN software clients without issue. This is an added bonus for the IT professional on the road.
To wrap things up; the TRENDnet TEW-655BR3G/A is a handy little device. At $89.99 from Newegg.com it is also a good buy for anyone who is on the road a lot and might want untether themselves from their 3G dongle. It is also fairly nice for use with the iPad and eliminates the need to pay for an extra AT&T account if you already have a 3G USB Modem. The robust firewall/router and the rechargeable battery only add to its value.
