Set the port speed on your laptop to a hard 1G / Full Duplex (or 1000M / Full Duplex) and see if it helps. Check the menu of the device and set the speed on this port to hard.

I'm guessing the supplier is Toya so he doesn't have access to the panel Toye comes only with the modem itself.

1. Check the configuration of the Ethernet network card. Are you sure it is configured to get addressings automatically. 2. You tried to update or reinstall the drivers for the Ehternet network adapter 3. Paste the command result Code: DosLog in, to see the code

1. According to the command, you have not turned off the WiFI card and the computer is connected with it. Perform while connected by cable. 2. Check the IP settings of the ethernet card. Is everything downloaded automatically from DHCP? 3. Execute the command after disconnecting and turning off the WIFI card. Code: DosLog in, to see the code

Yes, that was the place. However, as I can see, despite this configuration, the laptop does not receive an address from the router. Does the situation remain the same even after waiting a while after plugging in the cable? How is your access to the router's configuration panel? It is possible that the operator has limited what devices can be connected to the router, as long as he has access to the panel.

On the back of the router, you can have a sticker with the device's IP address (default). Remember to log in to the panel to be connected to wifi because from what I can see on the cable you do not get any address. Maybe, by entering the router model in google.pl, find its deafult ip address. Enter the password default ip adress or something like that.

1. Turn off WIFI (don't disconnect, just turn off the network card), turn off the computer. 2. Connect the ethernet cable, turn on the computer. 3. Check. Paste the command result while the computer is connected by cable: Code: DosLog in, to see the code

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 Added after 13 [minutes]: 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: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), @Epic

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.

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.

How is your access to the router's configuration panel? It is possible that the operator has limited what devices can be connected to the router, as long as he has access to the panel.

Maybe, by entering the router model in google.pl, find its deafult ip address. Enter the password default ip adress or something like that.

FAQ

TL;DR: 1 Gbps links can flap if auto‑negotiation misbehaves; "Set the port speed to a hard 1G / Full Duplex." This FAQ helps Asus A501LX + Cisco EPC3928 users stop 3‑second Ethernet drops and regain stable wired speed. [Elektroda, sanfran, post #17029357]

Why it matters: It quickly restores a stable, full‑speed wired connection for troubleshooting and everyday use.

Quick Facts

Observed Wi‑Fi speed was ~90 Mbps on a 150 Mbps plan in this case. [Elektroda, Anonymous, post #17029290]
EPC3928 LAN LED: green = 1000 Mb/s, amber = 10/100 Mb/s. Cisco EPC3928 User Guide
A ~2‑minute full power‑cycle with a reconnect order restored stable Ethernet. [Elektroda, Anonymous, post #17031881]
If the admin page fails, connect via Wi‑Fi and try the default IP from the label. [Elektroda, damcio1010, post #17031692]
Manually setting 1000M/Full Duplex on the NIC can stop link renegotiation loops. [Elektroda, sanfran, post #17029357]

How do I stop my Asus A501LX Ethernet from disconnecting every few seconds on a Cisco EPC3928?

Force the NIC to 1000M/Full Duplex in Windows. Disable Wi‑Fi to avoid route conflicts. Try a known‑good Cat5e or Cat6 cable. Reboot the EPC3928 and the laptop after changing settings. This stabilizes the link when auto‑negotiation loops. [Elektroda, sanfran, post #17029357]

What does the EPC3928’s orange vs green LAN LED mean?

On the EPC3928, a green LAN LED indicates a gigabit link at 1000 Mb/s. An amber LED indicates a 10/100 Mb/s link. Use Cat5e or better for gigabit. Cisco EPC3928 User Guide

Why does PING 8.8.8.8 say "General failure" when I plug in Ethernet?

Windows returns "General failure" when the TCP/IP stack has no usable interface or IP. In this case, the Ethernet adapter lacked a valid configuration and could not send packets. Fix the link and DHCP first, then retest. [Elektroda, Anonymous, post #17029371]

How do I check DHCP and IP settings for Ethernet in Windows?

Open Network Connections, right‑click Ethernet, Properties, then IPv4. Ensure both IP and DNS are set to Obtain automatically. Run ipconfig /all to confirm the adapter receives an IP, gateway, and DNS. If not, troubleshoot the link or DHCP. [Elektroda, Epic, post #17029424]

What power‑cycle order fixed this specific case?

Use this clean start sequence:

Unplug all router cables and power, wait about two minutes.
Connect Ethernet to the laptop, then the main coax.
Apply power last, then test the wired link. This restored stability here. [Elektroda, Anonymous, post #17031881]

I can’t reach the EPC3928 admin page. What should I try first?

Check the sticker or manual for the default IP. Connect to the router over Wi‑Fi, then browse to that IP. If it still fails, the operator may restrict access. Try a different browser and confirm your device’s IP. [Elektroda, damcio1010, post #17031692]

Should I disable Wi‑Fi while troubleshooting Ethernet?

Yes. Turn off the Wi‑Fi adapter, then reconnect the Ethernet cable and test. This prevents Windows from routing traffic over Wi‑Fi and confusing results. Re‑enable Wi‑Fi only after Ethernet works. [Elektroda, Epic, post #17030113]

How do I set 1.0 Gbps Full Duplex on my Realtek PCIe GBE controller?

Open Device Manager, expand Network adapters, open Realtek PCIe GBE Properties. On Advanced, set Speed & Duplex to 1.0 Gbps Full Duplex. Apply and reboot the router and laptop if needed. "Set the port speed on your laptop to a hard 1G / Full Duplex." [Elektroda, sanfran, post #17029357]

ipconfig /all shows "Media disconnected" for Ethernet—what does that mean?

It means Windows sees no active link on that adapter. Causes include a bad cable, disabled port, failing negotiation, or the router not providing link. Fix the physical link first, then obtain an IP. [Elektroda, Anonymous, post #17030172]

Why is Wi‑Fi slower than wired on my 150 Mbps plan?

In this case, Wi‑Fi delivered about 90 Mbps while the plan was 150 Mbps. Wired Ethernet can reach plan speed when the link is stable. Use gigabit Ethernet for best throughput and latency. [Elektroda, Anonymous, post #17029290]

Could my ISP be limiting devices or access on the EPC3928?

Yes. The operator can lock the admin panel and limit which devices connect. This may block DHCP for unrecognized MAC addresses. Contact support if you suspect provisioning limits. [Elektroda, Epic, post #17030246]

What quick Windows network tests should I run after plugging the cable?

Disable Wi‑Fi completely. Open Command Prompt as admin, run ipconfig /flushdns. Then run ping 8.8.8.8 to check basic connectivity and latency. Save outputs for support. [Elektroda, Epic, post #17030113]

Do different Ethernet cables or LAN ports help?

Testing multiple cables and ports is smart. In this case, two cables and different router ports showed the same drop pattern. The final fix required a clean power‑cycle and link setup. [Elektroda, Anonymous, post #17029290]

The LAN LED is green but there’s no Internet—what does that imply?

A green LED shows physical link at gigabit speed. No Internet then indicates DHCP failed or the gateway is unreachable. Check if the adapter obtained an IP address and default gateway. [Elektroda, Epic, post #17030246]

Will pressing the WPS button fix Ethernet issues?

No. WPS pairs Wi‑Fi clients and does not affect wired link negotiation or DHCP on Ethernet. Troubleshoot the cable, NIC settings, and router instead. Cisco EPC3928 User Guide

Did the fix hold long term?

Yes. The user reported that after the clean power‑cycle and subsequent reboots, the issue did not return. The connection stayed stable. [Elektroda, Anonymous, post #19106982]
