How do I tell if a router is a hardware failure?

For a router failure may be a software error or the hardware is bad, then how can we determine whether the hardware failure, please refer to the following article, I hope to help you.

These problems will cause the router to not work properly, the solution to the physical failure, the user can from the router device or Network Center ping command to check line connectivity, confirm the point of failure after the router hardware troubleshooting.

One, the system can not add electricity

1, this kind of fault problem shows that when the power switch of the router is turned on, the power supply light of the front panel of the router is not bright and the fan does not rotate. In this case, the first thing to check is the power system, to see whether the power supply socket current, voltage is normal.

If the power supply is normal, it is necessary to check whether the power cord is damaged, there is no loose, and then make the corresponding correction, the power cord damaged words on the replacement, loose the words will be inserted again.

2, if the problem has not been resolved, the problem can be blamed on the router's power. Check carefully, see if the router power insurance is intact, if burned then the problem should be resolved after replacement. After this step, if the problem has not been resolved, it will only be able to send the enterprise broadband router to a dedicated place to repair.

Second, the router component damage

1, this kind of fault problem is a kind of common in the router hardware trouble problem. The part where the problem occurs is usually the interface card. This type of failure is often manifested in two cases: in one case, when the problematic part is plugged into the router, the rest of the system can work correctly, but it does not correctly identify the part that is plugged in, mostly because the part itself is faulty.

2, another situation is that the inserted parts can be correctly identified, but after the correct configuration, the interface will not work properly, this situation is often due to other physical problems. The solution to this type of router hardware failure is to identify the problem by first confirming which of these is the case, and by replacing the suspect part with the same model.
