BT broadband users who have purchased Amazon's new voice-controlled speaker have encountered set-up problems.
The Amazon Echo is a hands-free speaker that connects to the Alexa Voice Service to play music, provide information, news, sports scores, weather and more in an instant.
However, many BT subscribers have struggled to get it connected with their BT Home Hub Wi-Fi and taken to Twitter to air their frustration.
BT has not yet officially commented on the matter, but an Amazon spokesperson has told the Guardian it is aware that a "small number of customers are currently experiencing issues connecting their Amazon Echo to some BT routers".
"We are working with BT to resolve this issue as quickly as possible," the representative said.
A number of users have managed to get round the initial problems by separating the 2.4GHz and 5GHz bands in their dual band BT Home Hub.
Echo uses seven microphones and beam forming technology to hear a person from across the room, even if music is playing.
Amazon also describes it as an "expertly tuned speaker that can fill any room with 360 degree immersive sound".
"When you want to use Echo, just say the wake word 'Alexa' and Echo responds instantly," the company said.
"If you have more than one Echo or Echo Dot, Alexa responds intelligently from the device you're closest to with ESP (Echo Spatial Perception). ESP will be available via a free over-the-air software update (coming soon)."
The rush of complaints on social media are further bad news for BT after Ofcom this week revealed it was the most complained about broadband provider during the second quarter of 2016.
BT racked up 26 complaints per 100,000 subscribers between April and June, just ahead of Plusnet, EE and TalkTalk.
The Alexa app has been updated to include a specific link to "pre-populate Wi-Fi settings for the small number of customers affected by connectivity issues with BT Hub routers".
