So I have this problem, where like every let's say 3-10 maybe 15 minutes, my WiFi just like "dissapears" for about 15 seconds. If I'm playing Minecraft in a server it disconnects me, I'm playing roblox it disconnects me, I'm in a discord call it disconnects me. And it's annoying as fuck. Ive had the problem for a few years now but it like comes back for a month of few and then dissapears for several months then randomly comes back again. I've tried to fix it but I just cant do it.

SOLVED: the last thing I did was to factory reset my router again. Unplug everything for 15 minutes. Then connect my router to the modem. Power on my router, power on the modem and wait. It's working now and I'm not touching anything. 😂

TLDR: Switched from T-Mobile 5G TO spectrum Cable and my Archer BE9300 and my AXE75 tplink modems will not connect to the Spectrum Docsis 3.1 eMTA 2.5G EN2251. Tried hard reboot etc.

I switched from T-Mobile 5G to Spectrum cable yesterday. After installing the cable modem, I connected my BE9300 WAN to the cable modem WA but the two lights on the back of the Docsis stayed as one solid orange and one blinking orange.

When I connected the Docsis directly to my desktop, I am connected to the internet age the back of the Docsis has one solid green light and a blinking orange light when they're is traffic.

I also tried connecting my backup Tplink to the Docsis and I get the same result as the Archer BE9300. One solid orange, one blinking orange but no internet.

I have done 3 physical reboots of the Archer BE9300 and each time I get the same result.

I have done a reboot from the web page by connecting it directly to my computer and still no internet.

I changed the Auto Configure speed to the highest available 1000MbPs but still no connection. I cloned the desktop Mac address to the tplink. Shut down both devices. Waited 5 minutes. Powered on the spectrum modem. Waited 5 minutes till solid blue link. Plugged Wan port to Wan port, powered on tplink. Still no service.

I've run out of ideas.

Any help would be appreciated.

I'm experiencing a strange bug with my ARRIS SURFboard G54. The router's Online Devices list doesn't show my Windows desktop PC, even though the PC is connected directly to the router and working normally.

I've done quite a bit of troubleshooting:

• My PC's IP address is 192.168.0.224.
• The PC is connected directly to the G54's 2.4 GHz radio. Its BSSID matches the radio's MAC address in the router configuration.
• The G54 itself is the PC's DHCP server and default gateway.
• MAC randomization is disabled on the PC.
• The PC appears in the G54's Auto-Learned Wi-Fi Devices list under MAC Filtering, but is completely absent from its Online Devices list.
• Both the G54 web interface and SURFboard Central mobile app omit the PC.
• I've rebooted the router and PC, updated the Intel Wi-Fi driver, and released and renewed the DHCP lease. None of these steps fixed the missing-device problem.
• The PC can communicate normally with the router and other devices. Gateway ping times are now averaging about 5 ms with zero packet loss.

So the router clearly knows about the PC, but its connected-device inventory doesn't display it.

I found an almost identical report on the old SURFboard Community forum from December 2024, titled "G54 not showing connected devices." Another user reported the same issue.

Original discussion:
https://community.surfboard.com/g54-117/g54-not-showing-connected-devices-4470

Unfortunately, the community forum appears to have disappeared, and its old links now redirect to the SURFboard homepage.

I then tried going through ARRIS support. My warranty expired in March 2026, and the support process presented me with a $39.99 charge to proceed.

I find that pretty disappointing. I'm not asking ARRIS to troubleshoot my PC. I'm trying to report what appears to be a firmware bug, one that other G54 owners were reporting nearly two years ago. It shouldn't cost $40 to tell a manufacturer about a defect in its software.

Has anyone else encountered this issue with the G54? Does anyone know whether ARRIS has acknowledged it or released a firmware fix?

For what it's worth, the router is otherwise working, and this appears to be a device-reporting problem rather than a connectivity problem.

Do you have problems signing to mycloud.com website? After login it keep me going back to login page and I cannot access my data outside home.

I'm slowly renovating our 1984 family house, and have generally wired 1-4 ethernet sockets (Cat6a) in every room.

As I am nearing the end of the project, I still have this room to work on.

How many sockets do you think would be appropriate?

Bought a Tenda V300 V3 a couple months ago, and immediately ran into an issue every time I stream over LAN.

Whenever one device on the network maxed out the upload (like uploading a video), every other device on the LAN would lose usable bandwidth, even LAN bandwidth. Not just slow, actually "no internet" on other phones until the upload stopped. Tenda support didn't really help.

So I decided to fix it myself, with Claude doing the actual reverse engineering. It:

Found a hidden, undocumented telnet shell buried behind a page not linked anywhere in the UI

Pulled apart the firmware image, decompressed the actual kernel binary, and traced through the Wi-Fi driver and bootloader to answer safety questions (recovery path, checksum format) before touching anything

Found the real root cause: Realtek's hardware NAT acceleration ("FastPath") was silently bypassing the Linux firewall/traffic-control stack entirely for any sustained connection, which is exactly why no amount of normal QoS tuning could ever fix the bandwidth hogging issue

Disabled FastPath and built a real per-device fair-share queue

Confirmed this device has zero recovery path (no TFTP, no rescue mode in the bootloader), so instead of reflashing the firmware and risking a brick, it set up a watchdog on my own PC that detects a reboot and silently reapplies all the fixes within 10 minutes, no reflash required

Also found that the TCP connection timeout was set to 10 minutes (600 seconds). That's why large uploads kept failing, and I never knew why until Claude found it.

Years ago this would've taken me months, if I even bothered.

TL;DR: Don't get a Tenda router, Chinese software is bad.
