Netgear Rangemax NEXT Wireless Router WNDR3300-100ISS vs WNDR3300-100UKS ?

There are two of the same wireless router listed on amazon. First one is the rangemax WNDR3300-100ISS which is listed at £74.00, excuse the links –

then there is the WNDR3300-100UKS version which is listed at £94.94!

Does anyone know that differences between the two and more importantly how does the UKS version justify the higher price?

That’s a good question, especially since Netgear’s own site doesn’t even mention the 100ISS vs. UKS designations!

A clue, however, is provided in the Extended Specs at the UKS Amazon llink. It reads "Localisation: English / United Kingdom." The 802.11 specs divide the 2.4-GHz band into 13 channels. In the US and Canada, only the first 11 are permitted. In the UK and Europe, all 13 are permitted. You can read more about this at

So my best guess is that the less expensive version is a US/Canada model, restricted to 11 channels, whereas the more expensive one (which is now £88.07, BTW) provides all 13.
