It's working very good with my iPhone, iPad, two iMac and a Mac Mini. However, when it comes to my Macbook Pro, they don't work as intended.
Before changing my router the wi-fi internet connection was very fine. So, I thought the router is having some problem, but it doesn't make sense since every other device I have is working very nicely. Then, I re-connected my Time Capsule to see if I can connect to internet with my MBP, and it works. So, I have no idea what's happening right now.
The problem is only happening with the new router, other wifi is working fine, like workplace wifi, tethering, etc...
I've checked if I'm having any error code or something but there wasn't anything I can find of. Now I don't know what to do.
Edit: So far, I've tried the solution recommended by comment below:
- Rebooting/Resetting router. Nothing changes.
- Resetting DNS settings. Nothing changes.
- Deleting network related plists(Method 2)+Reboot MBP. Nothing changes.
- Check if the problem is still occur in Safe mode. It does.
- Check if the problem is caused by 2.4/5Ghz bandwidth. No, it wasn't.
- Unplugged all USB devices. Still, there's problem.
- Changed MTU to 1492. Nothing changes.
- Tried creating new network locations. Nothing changes.
I'm only using DHCP because I use this mac when I'm not in home, such as workplace, so using a static IP address is not a very smart idea.
I am now talking with Apple to investigate what's causing the issue.
