Wavlink WL-WN578S2
I bought a WL-WN578S2 which worked for a time and then malfunctioned. I took it back to the shop and they replaced it. Just 4 months in and the replacement has failed. Wavlink.com site does not have this model on the firmware update options. I sought help on their website but like last time - absolutely no response. I do not recommend this company or it's useless product. Looking online I am not alone (hundreds of negative reviews). I will now try Tp-Link as have found their products to be superior in the past.
