Every router is different, but usually, they have a similar process for upgrading the router’s firmware.Here are the basic steps for performing a firmware upgrade, check your router manufacturer’s website for specific instructions for your make and model.Updating the firmware will delete some data from your Brother machine such as secured print data, caller ID log, journal report, outgoing message, and more (features depend on your model machine).We strongly recommend that you read the installation notes on the download page before running the firmware update tool.Note This method should be preferable, especially for EFI-Stub systems (some motherboard firmware might have issues with parsing/passing custom boot command line options), since these changes are less likely to leave your system unbootable (and possibly unrepairable without an EFI compatible rescue disk which can be very tricky on headless machines) the way a broken firmware boot entry and/or incorrect initram-fs/disk would, while it also works on BIOS systems or EFI systems with custom bootloaders on disk.
Usually, your router manufacturer will provide firmware updates for your specific make and model of router, via their website, or via a tool within the administrative console of your router (typically accessible via a web browser).
Add the generated microcode to your kernel command line as an initrd parameter (this should be done even if you don't use an initrd image in order to boot, the microcode update merely leverages the initrd hooks): [ 0.000000] microcode: microcode updated early to revision 0xa4, date = 2010-10-02 [ 1.207385] microcode: CPU0 sig=0x6fd, pf=0x80, revision=0xa4 [ 1.207393] microcode: CPU1 sig=0x6fd, pf=0x80, revision=0xa4 [ 1.207445] microcode: Microcode Update Driver: v2.01 Note The microcode-ctl utility has been deprecated as of 1.28-r1 (Gentoo unstable) and will no longer contain the init script.
It also does not work on certain CPUs such as Intel Haswells, the information below this point is only relevant to microcode-ctl users.
Many routers use 192.168.1.1 as this address but it does vary.
Here are some common default addresses fro some of the more popular wireless router brands.
