There is only a couch close to it. However, I know that's not the problem, because I had the same issue with it when I had the TP Link located upstairs in our master bedroom, and it wasn't close to any furniture at all.

I again had to reboot it early this morning. It worked for about 4 hours, then lost internet again. I rebooted again and had no connection. Rebooted again and then it worked.

I ended up upgrading my router to a Netgear Nighthawk X6S AC6300, and moved the TP link closer so that I was getting around -54 dbm in signal for the 5G band (I was hovering around -68 in the previous spot). That appears to have solved the problem...no dropped connections so far.

I get the same thing every day and often. I have laptops and tablets that constanly lose connection. I usually ahve to reset the range extender to get those devices back online. I have the RE 450's also and the Netgear C7100V Router/modem.

This extender is garbage I guess. I have the same problem. The extender is sitting next to the router with full signal. Th extender works fine for a day or so and suddenly drops the connection and at this stage the extender doesn't even respond to power down switch. Have to physically remove the extender from the outlet and reconnect it back and it will work for a day. Mailed the customer support and told to change the channel of Tx/Rx in the router to particular channel. Will try that and update. But very disappointed with this product.

I filed a ticket for support and some one got back to me promptly. I was asked to fix the Tx channel in my router to a fixed one and also restrict the Tx Bandwidth from the router. I tried that and the extender was up for 2 days and then crashed. I was with a customer respresentative from tp-link online and the representative logged into my extender and fixed something and the extender worked for 3 days and has crashed now. He also checked and said the extender is receiving good sgnal strength. I sincerely feel there is some bug in the extender and going by the discussions in the forum, this seems to be a problem. With this perceived instability no one at my home wants to connect to the extender as the extender might crash in the middle some important thing!

It is ok 65$ went down the drain but the bigger worry is the creation of electronic waste to landfill. Truely disappointed. If any of you have any suggestion please let me know and I will try them as well. 

Thanks for your help and time.

I have the same problem with my RE450. And I think blaming the router for this bug is just SAD! Al other WiFi divices connects for weeks (until manually reboted either the router or the device itself) Why is this Extender not capable of maintain the connection? You guys at TP-Link should accept you need to fix this with some Firmware upgrade. I'll never buy any other TP-Link product.

@Sinap 

I was with the Senior Engineer again and he tried to retrieve the status of the extender after it has crashed and was not successful. When it crashes, nothing can restore the device  - not even the reset by pushing a pin through the reset hole - except yanking the device from the power port and re-connecting it. The senior engineer said he will do an RMA of the device and I told him that there are many folks in the forum experiencing the same issue and he said the cause is different. I don't know what exactly the cause is and if so they should publish the fix. 

I am doubtful the replacement extender will be any different. I will update once I receive the new device and try that. Thanks for your time and help.
