Hi

I have multiple ADSL+ internet connections in my workspace. Last month, I purchased a R480t+ for load balancing, intending to increase my bandwidth. (R470t+ was out of stock) I set it up for load balancing (I checked load balancing under transmission menu and unchecked Optimized routing. I then configured 4 of the ports as WAN and connected my ADSL modems to them. I had an old W303R router from Tenda that I hooked up to the LAN to act as an access point, and it did without any additional settings for the past month.) Last week I decided to increase the range of internet access and purchased an Archer c60 for this purpose. I connected it to the LAN output of my R480t+ and set it up, expecting it to work out-of-the-box considering I'm using tplink modems, loud balancer and now access point, but it didn't. The internet LED turns red randomly, and I get a connection error on mobile phones and pc/laptops connected to Archer (Sometimes it asks for sign-in on smartphones). I decided to change its operation mode from router to access point, and it still has the same issue (on router mode, I set it up as dynamic ip internet access.) As a test, I connected Archer C60 to a single modem and it worked perfectly. Is there any additional steps that I'm missing? Should I configure them differently? I appropriate any help!
