[Solved] Title: Internet Disconnects after 3 Seconds on Asus A501LX DM099 with Cisco EPC3928 Router

Hello.

First of all, I would like to apologize if I am writing this topic in the wrong section - I was not sure whether to put it here or in the "Hardware, Software" section, however looking at the topics in both departments, I decided to add it here. transfer.

My problem is that after connecting the Internet via a cable (from the router to the laptop), the laptop connects for about 3 seconds, and then disconnects another 15. The router also lights up an orange LED for about 3 seconds, which should be on green like the rest. This is best illustrated by my film that I recorded for this topic:






Tested on two ethernet cables, same on both, laptop drivers updated. Turning off Wi-Fi, changing the Ethernet socket on the back of the router or resetting the router does not change anything.



Router Model: Cisco EPC3928

Laptop model: Asus A501LX DM099



When I connect via Wi-Fi everything is ok, but I have a drop of 60Mbps, so I decided to connect the internet via cable, in the end it is a bit stupid to pay 150Mbps for internet and receive about 90Mbps via Wi-Fi.



Thank you in advance for your help.

Could you write me down step by step how to do it? I am so sorry for my lack of knowledge, the computer is not my strongest point. @sanfran

I turned off my laptop, connected the cable and restarted it. Interestingly, now the LED was flashing green instead of orange, but there is still no internet. After typing in the command prompt: ping 8.8.8.8 I got:

PING: transmit failed. General failure
PING: transmit failed. General failure
PING: transmit failed. General failure
PING: transmit failed. General failure

Ping statistics for 8.8.8.8:

I am so sorry, I was sure I unplugged the card.
Here's what I got after turning off the WiFi card and connecting the cable to the laptop:

As for the IP settings of the ethernet card, I'm not sure if it is, but after right-clicking on Ethernet and entering the properties in Control Panel-Network and Internet-Network Connections
Next
Internet protocol version 4 and after clicking properties, everything is set to automatic there. If it is not, I would ask for a possible explanation of where I have to go.

After executing the ipconfig / flushdns command, I got the answer:

Windows IP Configuration
Succesfully flushed the DNS Resolver Cache.

There is no change, whatever I do the problem remains.

When it comes to accessing the router's configuration panel, I have no idea about it, I never played around with its settings, because I was afraid that it would break something, and thus I don't even know how to check if I have access to the panel. I only know that on the router I have a button with two arrows spinning to the left (as far as I know this button is called WPS, but I will not cut my head).

There is a sticker under the router which does not have the IP address of the device, but I found such an address in the manual. After entering this address, it loads for a while and then crashes the error: "This site is unreachable". I tried on three browsers and the same on all of them. After connecting with the cable unchanged. I tried to disconnect the main cable connected to the router (the one on screwing), and connect the router to the laptop, interestingly the diode was not blinking, only was on normally, but still the same error after entering the IP address of the router.

Added after 42 [minutes]:

Okay, a bit weird, I unplugged all the cables from the router and left it for about 2 minutes, then plugged the ethernet cable into the laptop, then into the router, the main cable (screwed in), and finally the power, and now it connected normally over the cable and I have Internet. After a few reboots of the router and laptop, everything still works fine, the speedtest shows correct results, so it turns out that it fixed itself (?). It is very strange for me, especially since I have done it several times before, but it did not bring any change, but I will not complain. For now, I leave the topic open in case the problem returns. Thank you for your help.

Since then, there have been no more problems.
