Model: TL-R480T+  
Hardware Version: V9
Firmware Version: 20180117

Hi,

 

My TL-R480T+ always usage 100% of CPU

 

Always that a user start a download file heavy the CPU goes up to 100%.

 

The router stay very slow, almost impossible the access.

 

Before I using this router, we had a equal router but the version 7 and don't these problems.

Hi thiago.ferreira

 

The high CPU can be caused by many things. Like high traffic and some data that need to be processed by CPU.

I saw TP-Link has the new firmware for TL-R480T+, maybe you can try to upgrade it.

Hi thiago.ferreira

 

As I knew, TL-R480T+ only has the (UN) version for all region. So you can update the firmware to 20180926.

Can you please confirm the following.

 

1. is DHCP switched on ?

2. What's is the IP range of the DHCP ? If it is switched on.

3. what is the number of client computers that are connected to this LB?

 

You can try switching the DHCP server off and check (in case there are a few clients this is relatively easy) This is a issue I faced with 64+ clients.

 

If nothing works, after upgrading the firmware, reset the LB and reconfigure it from bottom to top.

 

Best of Luck

@thiago.ferreira 

 

The TL-R600VPN has the same problem !

I have 300 megs wan to a network with 12 pcs and anything more stout, makes the TL-R600VPN crash.

On webadmin cpu at 100% charge, it is even difficult to load this webadmin, the product seems to be weak.

 

(Thiago, o TL-R600VPN tem o mesmo problema, tenho Vivo Fibra de 300 megas numa rede com 12 pcs e qualquer coisa mais parruda, faz o TL-R600VPN travar.

Vou no webadmin dele e ele está a 100%, inclusive é dificil até carregar este webadmin, o produto parece ser fraco.)

@thiago.ferreira HI, does anyone was able to fix CPU issue with TL-R480T, I bought one but CPU is almost 100% and its impossible to have internet access. This happened after enable the 4 wan ports to load balance 4 different internet access. It look was not design to support this. With just one user and not dhcp enable the cpu is almost 100% all the time.

Dear @Marco94,

 

This old post is out of date. It would be recommended to start a new thread to discuss the problem.

 

I bought one but CPU is almost 100% and its impossible to have internet access. This happened after enable the 4 wan ports to load balance 4 different internet access.

 

Please check the hardware and firmware version of the R480T+ router, ensure it is running with the latest firmware first.
