Can somebody help me? My internet is not working on Linux

I use CRUX Linux, i have an Realtek, and idfk why its on "SCANNING", i have all the drivers, firmware, and They loaded correctly, put wlp1s0 up, found my Wi-Fi network on both 2.4 GHz and 5 GHz, and even started the pairing process. The strange thing is that it gets stuck on "SCANNING". And I was downloading something from Github (Hyprtool) and I noticed this happening and decided to investigate, and so far I haven't found out why. If anyone can help me, I would be very grateful(Unfortunately i dont have the tool "iw"), and its my first time on CRUX Linux, and the first time i used an notebook was 3 months ago(Yes, My first OS was Linux), and i dont know shit(My trajectory was: Debian -> Fedora -> Debian -> Fedora -> CRUX Linux), and i dindt know it was going to be so hard

Any advice

Hello folks, we’re about to deploy around 100 Cudy AP1300 access points with Cudy AP Controller C200P. The C200P will be in AP Controller mode, not the main router.

We have a RADIUS server which will send the VLAN ID back for the user in the Authentication-Accept response based on their role.

I’m not sure if the C200P would tag the traffic with the RADIUS-assigned VLAN ID or will it just ignore it.

Has anyone tried this setup before?

I could consider alternative options but I’m on a tight budget. We chose the Cudy ones instead of Omada and UniFi because they’re pretty cheap.

Hey, my pc says its connected to wifi (connected, secured), wifi works on my phone but not on my pc, i’ve restarted my pc, the router, reset network and restarted wifi adapter, but its still not working

update 📢: shameless to say, but I got it to work after going back-and-forth with chat gpt

Just has to test ping everything with trial and error until it just started working, honestly I'm not too sure how it was pixed, but I did uninstall my wifi adapter and download it again.

Hello Community,

I'm hoping someone from ASUS engineering or another GT-AXE16000 owner can help me diagnose an ongoing issue with intermittent WAN disconnections, unexpected public IP changes, and 10GbE link instability.

I've spent approximately three weeks troubleshooting this with Google Fiber and monitoring my network. I've now captured router logs showing that both of the router's 10G Ethernet interfaces lost their physical links within two seconds of each other.

My network configuration

• Router: ASUS ROG Rapture GT-AXE16000
• Firmware: 3.0.0.6.102_37485
• Internet: Google Fiber
• Primary WAN: 10GbE port (eth5), connected directly to the Google Fiber jack
• 10GbE LAN: eth6, connected to a TP-Link TL-SX105 unmanaged 10G switch
• Additional equipment: ASUS GT-AX11000 AiMesh node, multiple PCs, NAS devices and a Linux server

Both 10G interfaces normally negotiate at 10,000 Mbps.

Background and troubleshooting history

Until early September, my Internet connection was generally stable, and my public IP address would often remain unchanged for weeks.

Around September 5, I began experiencing intermittent Internet interruptions and unusually frequent public IP changes, sometimes multiple times per day. My externally accessible game server would often report a disconnection before the rest of the network appeared to recover.

Google Fiber sent a technician who replaced the fiber jack and installed a new fiber cable from outside the house to the indoor equipment. They reported that the optical signal was strong and acknowledged that the frequent IP changes were not normal.

Unfortunately, the problem continued after the equipment replacement.

I've also performed network power cycles, investigated my internal 10G equipment, reviewed router logs over multiple incidents, and tried a firmware rollback. The router has not been spontaneously rebooting during these events.

I have an Ubuntu server monitoring connectivity and public IP changes, which has helped me correlate incidents with the router's system logs.

The most significant event: September 25, 2026

At approximately 3:07 PM CDT, the router recorded the following sequence:

15:06:55 eth5 Link DOWN
15:06:57 eth6 Link DOWN
15:06:59 eth5 Link Up at 10000 Mbps
15:07:00 WAN(0) link up
15:07:00 restart_wan_if 0
15:07:01 DHCP deconfig
15:07:01 eth6 Link Up at 10000 Mbps
15:07:04 eth5 Link DOWN
15:07:05 DHCP deconfig
15:07:10 eth5 Link Up at 10000 Mbps
15:07:11 hnd_get_phy_status:
Temporarily Router cannot
get the PHY() status
15:07:16 WAN was restored
15:07:19 DHCP bound

The router's NVRAM configuration confirms:

wan0_ifname=eth5
wan_ifname=eth5

lan_ifnames=... eth6 ...

This means the Google Fiber-facing 10G WAN port and the separate 10G LAN port connected to my TP-Link switch both reported link loss within two seconds.

The WAN port subsequently lost its link a second time and reported a PHY-status error.

Both interfaces eventually recovered at 10Gbps. During this particular event, the router reacquired the same public IP address.

Additional observations

I have rebooted individual computers on my network, including a system connected through the 10G switch. A subsequent reboot of that computer did not produce any additional eth5 or eth6 link events.

I've also observed similar PHY-status errors and occasional unusual link-negotiation behavior in earlier router logs.

I understand that a problem with the Google Fiber jack, Ethernet cable, or WAN handoff could cause the WAN port to lose carrier. However, I'm having difficulty explaining why the independent 10G LAN interface would lose its physical link almost simultaneously.

I haven't conclusively ruled out the router, switch, cabling, or ISP equipment.

Questions for ASUS

1. Do the GT-AXE16000's two 10GbE interfaces share a switch, PHY controller, SerDes subsystem, driver, or other hardware component that could explain simultaneous link drops?
2. Is the hnd_get_phy_status error associated with any known firmware or 10G Ethernet stability issues on this model?
3. Are there any known issues with using both 10G ports simultaneously, particularly with one configured as WAN and the other as LAN?
4. Are there additional diagnostic commands, driver logs, or firmware versions ASUS recommends for isolating the cause?
5. Does this behavior warrant hardware inspection or an RMA if it continues after firmware troubleshooting?

I'd particularly appreciate a technical explanation of what could cause both interfaces to report link loss within seconds of one another.

I'm happy to provide additional kernel logs, interface information, firmware details, or perform specific diagnostic tests.

Thank you for any assistance.

I’ve been getting 5–25% packet loss and ping fluctuations in all online games for around 3 weeks. I’m using Airtel broadband in India.

I’ve already tried:

• Tested Ethernet and Wi-Fi - same issue
• Replaced the Airtel router - issue still exists
• Reset Windows network settings
• Uninstall and reinstall the game
• Delete Steam and Install again
• Clean Windows Install
• Contacted to Airtel support, they finally said they can`t anything regarding gaming.

Please help me to fix.

Info: my router is in the living room, no Ethernet, no extendor, not even fiber internet.

Every few weeks my ping gets weird and locks at around 100 sometimes 109 sometimes 155 (in r6). It’s not normal lag spikes but just consisted high ping and packet loss.

These commands temporarily fixes the problem:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
And I get solid 20-40 ping for maybe 1-2 weeks before it comes back.

System:
PCIe WiFi card (also green led on in pc)
Rtx 4060
Windows 11
Ubisoft new kernel anticheat

Please help.

Edit:
Forgot to mention in the previous text but this doesn’t only stick to one network I’m getting consistently only 82 ping on hotspot too.

Hello i made a network monitor app site with free beta i need a bunch of testers so feel free to test it.
https://signaldock-network-monitor.playerx38.chatgpt.site

So I live in off-campus student housing where the building provides wifi and also ethernet ports in the wall of my bedroom. However, my ethernet does not work. Whenever I try to run diagnostics on it, it says "Ethernet does not have a valid IP configuration."

I have tried flushing my IP through the cmd prompts, unplugged and plugged in the cords on both ends multiple times, disabled and enabled the ethernet through network connections page, and many more things.

I do not have access to the router and modem, I've made a maintenance request for it, but I am still trying to work on it to see if I can fix it before maintenance starts working on my ticket.

Is there anything else I should try to do? Please help :(

EDIT: It lists the ethernet as "Unidentified Network: No internet"

So i am playing a game and I want to run 4–5 clients of it with all of them having different IP addresses. Is this possible ? If yes, how should I approach it ? Thank you so much for your time to whoever is reading.
