A new piece of “research<\/em>” from Broadband Genie<\/a> has claimed that Christmas trees can slow your “internet speed<\/em>” via WiFi<\/a> by up to 88%. This is said to be due to how the tree’s “pine needles, branches, fairy lights, tinsel, and baubles can absorb and deflect your router\u2019s Wi-Fi signals<\/em>“, causing it to “slow and reduce its range<\/em>” throughout the home. But it’s not always that simple.<\/p>\n

\u201cI was shocked to discover just how much of a difference it can make. I first noticed when I couldn\u2019t receive signal in some parts of our home and my video calls for work became jittery. Our house isn\u2019t massive, so there is nowhere else for the tree to go. I\u2019ve moved it away as much as I can from the router, and it has since made it a bit better. I just wish I knew this before we decorated it!<\/em>,\u201d said Sophie from Cambridge.<\/p>\n

NOTE:<\/strong> See our Top Tips for Boosting Your Home Wi-Fi Wireless Network<\/a> guide for more advice.<\/div>\n

According to the press release, Sophie previously experienced download and upload speeds of 193Mbps and 26Mbps, respectively, prior to putting up the Christmas tree. But these fell to 134Mbps (-31%) and 3Mbps (-88%), respectively, after the tree had been erected in her living room.<\/p>\n

However, we have to question this study because it appears as if the test was only based on a single user’s experience, as opposed to using multiple users in different environments with different scenarios and establishing proper baselines to produce a more scientifically credible output. The press release also fails to identify precisely where the router was located in relation to the tree, which is important.<\/p>\n

Can Xmas Trees Slow Internet Connectivity?<\/strong><\/span><\/h3>\n

The key point above about Christmas Trees being able to disrupt WiFi<\/a> is indeed correct, although how much it impacts your home does depend upon a lot of different factors, such as precisely what you’ve put on the tree, what materials it’s made from, the radio bands being used (2.4GHz, 5GHz and 6GHz) in your network\/devices and the location of your router \/ tree etc.<\/p>\n

For example, if the main router is in another room and the Christmas tree is near to an end corner window, then it’s less likely to have a dramatic impact on overall performance. In this case, it sounds like the router and tree were initially placed very close together in the same room, which would of course be very counterproductive to signal propagation and performance around the home (concealing routers behind things can weaken their reach).<\/p>\n

It\u2019s also well-known that some older style blinking Christmas Tree Lights<\/strong> (blown glass bulbs with a carbon or tungsten filament) could cause a bit of interference for those with copper line broadband services (e.g. ADSL<\/a> and FTTC<\/a>\/VDSL\/SOGEA), which if you\u2019re not careful might even impact your connection stability. But this tends to be less of an issue with modern LED lights, and keeping the tree well away from your modem\/router will help.<\/p>\n

Before going to press we conducted our own very anecdotal test, although in this case our router was positioned upstairs on the landing (central to the house) and the Christmas tree sat downstairs in the living room. Overall, we noticed no appreciable decline in WiFi<\/a> performance vs baseline to any devices, but then we have none connected near to the tree itself.<\/p>\n

As above, if you do suffer a performance detriment on your WiFi, then it may be time to consider a wireless mesh solution or perhaps even running a wired link around the home. Powerline adapters (e.g. the TP-Link TL-PA7017P KIT<\/a> for \u00a344) are also an option, although these have their own set of caveats.<\/p>\n

We’d of course be interested to hear about any other before vs after (tree deployment) results from other visitors in the comments.<\/p>\n

UPDATE 11:11am<\/strong><\/p>\n

The comparison site has informed us that the test was conducted using a single router positioned 4 meters away from the device (laptop). The tree was placed between the router and the device, so the results are not too surprising.<\/p>\n","protected":false},"excerpt":{"rendered":"
