Re: Debian on Netgear RN102 - 12 days ago

Hi bodhi, Quote I'm afraid that for this box, like other 32-bit processors with single CPU, the performance might get worse. You are right. The performance loss is about 10% (ranging from 7% to 11%) when upgrading to a kernel with symmetric multiprocessing. Not much to do about it, I guess, if keeping the kernel current is desired. I repeated the tests above from 8 years ago with Li

Hi Adrien, Thanks for investigating! This starts looking like some hardware difference. Could it be that I have an older version of the SoC than you? These are the details of my CPU: tme@rn102:~$ lscpu | head -14 Architecture: armv7l Byte Order: Little Endian CPU(s): 1 On-line CPU(s) list:

Hi adrien, Your 'dmesg' log show that my RN102 and your RN104 boot at the same rate for about 2.0 s. Then my RN102 is delayed for about 1.2 s, but after this delay, the boot processes again progress at the same rate for about 0.6 s. At this point the PCI bus is polled with diverging results due to hardware differences. Attaches a file created by 'paste' where every second l

Hi bodhi and adrien, Quoteadrien60 Curiously, no lag for me This came as a surprice! I originally discovered the lagging on my RN104. It died a year ago, so I cannot repeat the test on RN104 today, but I have no reasons to believe it would differ from RN102. I have two RN102s in continous operation, one making nightly backup of the other. I just repeated the test on the other RN102 whi

Re: GTI Mirabox, Netgear RN102/RN104, Netgear RN2120 Installation & Kernel Upgrade (Linux-6.17.7) - 28 days ago

Hi bodhi, When I discovered the lagging some years ago, I estimated it at 6 to 7 s/min, but actually it was 1 h in 11:56 h or 60*60/(11*60+56) = 5.03 s/min as reported here. My hypothesis is that the source of the lagging is lost timer interrupts. If I've understood correctly, a fast spinning 32 bit hardware timer (sched_clock@19MHz) creates an interrupt each time the 64 bit system clo

I'm sorry, adrien, for responding late on your October 16 post! 8 years ago i reported Linux kernel 5.9.3-mvebu-370xp performance on Netgear RN102/RN104 at 59% to 81% of the stock kernel performance on some simple network tests not involving disks. I expect similar results if the tests were repeated today, but would be thrilled if you prove me wrong! Regards, Trond Melen

Re: USB-to-WiFi adapter not working with Linux 6.15 (driver issue?) - 2 months ago

Hi bodhi, QuoteIt also works if we put the essid and password in /etc/network/interfaces and then protect this file with chmod 600. I've come to realized that the range of these very small USB-to-WiFi adapters is very short, maybe just 2 meters (6') or so. When I've been unable to reproduce issues, it may just have been thet the distance between the box and the wirless router

Re: USB-to-WiFi adapter not working with Linux 6.15 (driver issue?) - 2 months ago

Hi bodhi, Problem solved. It was not a driver issue. Modifying '/etc/network/interfaces' is sufficient to connect to an open WiFi network, but to connect to a WPA or WPA2 protected network, the 'wpasupplicant' package is needed. This makes sense since '/etc/network/interfaces' is normally readable for everyone and should not include any passwords. sudo apt i

Re: USB-to-WiFi adapter not working with Linux 6.15 (driver issue?) - 2 months ago

Thanks bodhi, So the root file system is mounted before WiFi interfaces on USB ports are probed? I didn't know. I had no success when blacklisting any modules. When 'rtw88_8821au' is blacklisted, no other relevant modules are loaded, and 'ip a' reports no wireless interfaces. I no longer believe 'cfg80211' is a replacement for 'mac80211', rather

Re: USB-to-WiFi adapter not working with Linux 6.15 (driver issue?) - 2 months ago

Thanks for trying, bodhi! Since the firmware file '/usr/lib/firmware/rtw88/rtw8821a_fw.bin' is missing in Debian 12, I assume support starts with Debian 13. My impression is that the new driver 'mac80211' (merged in kernel 6.13/6.14) is supposed to replace 'rtw88_88*', 'rtw88_core and 'cfg80211''. I think the problem might be that both 'cf

Re: USB-to-WiFi adapter not working with Linux 6.15 (driver issue?) - 3 months ago

Hi bodhi, To investigate further, I rolled back to Linux 6.13.8 and 6.12.6. I found no relevant differences between version 6.15.2 and 6.13.8. With 6.12.6 the USB-to-Wireless adapter is not supported. The device is detected, but the kernel does not try to load the firmware, and 'ip' does not report any wireless devices.

USB-to-WiFi adapter not working with Linux 6.15 (driver issue?) - 3 months ago

Dear All, I've installed a USB-to-WiFi adapter in a Neatgear ReadyNAS RN102. The box is now able to scan for WiFi networks, but is unable to connect. The error message is "No DHCPOFFERS received". Connecting fails the same way on a second network. The adaper is a TP-Link AC600 Archer T600U Nano. It's the kind of adapter that barely extends out of the USB connector on the

Hi bodhi, Quotetme According to 'ethtool', the wakeup-on-lan support differs between the two ports ("pg" vs." d"). Adrien60 got it right. By bringing up 'eth1' too, 'ethtool' reports the same support "pg" on both 'eth0' and 'eth1'. Sorry! Regards, Trond Melen

Hi bodhi, Quote I recall we removed the audio controller node from the DTB and the time lag was reduced a bit. Was that 4.9 s/min ? or is 4.9 s/min the original lag? Originally, the lagging was between 6 and 7 s/min (see https://forum.doozan.com/read.php?2,133814,133814#msg-133814). Regards, Trond Melen
