## Description

Buy

Review: Excelent Router - I bought this Router to replace the one provided by my isp and I m very pleased with the results. The previous router had a limited NAT table and I had a lot of lost connections. With this router I saw over 90000 connections without a single problem. I can't test the multiwan feature yet, due to owning only only VDSL line. The interface is easy, but there are some small issues that need updating (Works fine with a time server but no provision for time saving changes, Some of the status screens are hidden inside other menus etc.) Overall a very good router with a very sensible price.
Review: Excellent Load Balancing Router - Very pleased with this simple router. Purchased for its load balancing capability which works well. Simple interface, maybe a bit old fashioned but functional. One of our broadband connections failed recently and we didnt notice as the router just pushed all the traffic onto the remaining working line. Excellent. Reset the failed connection and load balancing resumed.

### ⭐⭐⭐⭐ Good but not fantastic
*by D***E on 18 April 2014*

I purchased this router to help be load-balance my multiple broad-band connections. As I'm a freelance contractor, I have multiple connections mainly for resilience and I purchased this router to automatically switch between them. It works quite well for the money, but I'll be replacing it soon with something more sophisticated. As a 'plug and play' device it works quite well, but if you want to get under the hood and make some more advanced changes you'll run into trouble. What I liked was that it will automatically balance each device on my network to use the connection with the most available bandwidth, it will also filter traffic to a standby connection if one of the WANS fail (though you'll need the latest firmware for this to be reliable). What I didn't like is that it's not possible to route devices to a specified connection, this can be hassle when you have secure connections or you have services bound to a particular WAN IP, features that are available on more sophisticated devices. It's also frustrating that each WAN connection is limited to 100Mb, so if you have Virgin's top of the line connection then it will be limited by this device. In summary then, a good value device that is reasonably straight forward to use (though they don't use standard network terminology to describe some of the menus), but it might disappoint users who are looking for a truly 'professional' piece of kit.
