Interfering between TL-WR940N and TL-WA701ND

I have the following network configuration in my home:
1. TL-WR940N Wireless Router setup and connected to ADSL modem through LAN. Both are located in my workplace room.
2. TL-WA701 Access Point configured as a Repeater and placed in the middle of the home; around 6 meters far away from the wireless router in the workplace room.
3. The router and repeater configured successfully and work as expected.
4. No electric devices exist around the router and repeater which may interfere/block the signals.
5. The number of devices that connect to the router and repeater is up to 6 devices.

The problem is that occasionally (couple of hours) while am working on my Windows-power laptop in my workplace room, the laptop loses the wireless connectivity to the root router, which is 1.5 meters away, and the wireless utility shows that am now connected to the repeater instead (I can verify this by checking the MAC address). Internet connectivity still operating but very slow or interrupted. However, my smartphone in the same room works perfectly and still show full wireless signal to the root router!

At the same time, other family members who set close to the repeater and use an iPad and Mac laptop, start to notice the wireless signal is weak and lose internet connectivity or have it very slow.

The easiest solution is, thought, to have a power recycle for both routers and reconnect again which is not reliable solution.

This sounds to be an interfering/blocking of radio signals which am not able to understand or resolve.

Any help please?

There are two issues that repeaters cause:
1) They are on the same frequency channel as the primary router so your two devices can start to really interfere with each other
2) A single-radio repeater has to use the same radio to send data from pc-router and router-router so it divides your bandwidth in half.

Im assuming that running ethernet form primary router ot access point is not an option.
Next best solution is to upgrade both devices to dual radio routers (2.4 ghz and 5.8 ghz radios). Then you can have your router-router communication over the 5.8 band and then you can have your primary router and access points on different channels on the 2.4 band

Next best solution: Buy a dedicated wireless bridge to recieve signal from...

When you have a repeater setup using the same SSID windows will try to automatically connect to the source with the best signal; this can be a hassel when widnows keeps switching back and forth, espically if it sees a bogus increase in signal from the router/access point you are not using.
