hi, I just bought the new Lenovo yoga c740 i7 and since then whenever I connect to my home wifi which is talktalk, the wifi basically crashes and everyone in our house devices is disconnected. I saw online that this problem is quite common but I haven't seen one with this laptop so does anyone have any suggestion? I would very appreciate it

That's quite interesting. Have you tried contacting your ISP to change the WIFI channel or the WIFI password and refresh the connection?
Check for Windows and Driver update using the Lenovo Vantage and make sure that the laptop is up to date.

Update us how it goes.

Hope everything went well after the router replacement. You might also want to connect to a different WIFI network to isolate the problem while waiting for the replacement router.
Keep us poted.

Hi so after the new router replacement, it still did not solve the issue, so I upgraded to 40mbps download and this improves it a little bit. I also tried setting it to a metered connection and disable background apps. With these, the situation got better but the issue is still not solved. Before it was whenever I connected, the wifi basically disconnects every device and nobody can use it for a while, now its less frequent but still happens. I connected to my university wifi and that still works. I had a Lenovo laptop before and this never happened!

Seeing the exact same issue here. Wifi is normally very stable. As soon as I connect my new yoga C740 the wifi keeps disconnecting on all devices on the same wifi network every few minutes.

I just received my new Yoga C740 (14") on Friday (Jan 24) and we started seeing random brief wifi shutdowns in the house. We tried resetting the router (a Linksys model WRT1900AC) on Saturday, but that did nothing. I didn't make the connection between the frequent wifi issues and this new laptop until I came here to search for compatible pens. Hopefully someone comes up with a genuine fix for the problem.

I may have found a solution for this issue. After uninstalling the seemingly useless preinstalled app 'Lenovo Utility' I have not seen any WiFi issues anymore. Perhaps someone else can confirm if this works for them too?

5 days have passed since I uninstalled Lenovo Utility and still everything seems to be fine. Anyone else who has had the opportunity to try this out? I am very curious to know if this really is related to this tool as this may help in giving the Lenovo team something to look at.
