This has caused major headaches for me and a number of my clients that I have supplied these TL-WN881ND US version cards to as the US cards have frequency restrictions in line with US regulations, they can only use and are restricted to channels 1-11 as when used in the United States that is their regulation for use of wireless frequencies.Īfter spending a considerable amount of time investigating wireless issues for a client in 2019 and then concluding that the US version WiFI adapters were the cause of the issue when modems/ gateways/ access points were using channel 12 or 13, I have been forced to spend a considerable amount of time replacing all the US adapters in my client's systems which has seen me lose thousands of dollars in labour and travel costs along with lost revenue to resolve an issue that TP-Link have created. ![]() ![]() ![]() There, I am an IT tech in Australia and I have found that TP-Link have been distributing US version TL-WN881ND cards in Australia over the last few years (first noticed in 2019 and I have seen more US version cards when I purchased some in the last couple of weeks in the hope they stopped distributing the US ones but frustratingly and obviously haven't).
