So this morning I proceeded to put the DD-WRT Mini into there (v24 SP1 Stable Generic Mini), using the below steps :
(00) Save various instructional web pages to offline as suggested
(0) Make & save Screenshots of current router GUI config screens
(1) Download firmwares and confirm MD5 hashes
(2) Set router LAN IP to Linksys default 192.168.1.1 and a PC to a static IP on the same subnet
(3) Do a 30-30-30 Hard Reset of router
(4) Bring up router GUI again using default admin/admin
(5) Do firmware update to DD-WRT Mini from within factory GUI
(6) Log into router DD-WRT for 1st time, using default of admin/admin, IIRC
(7) Do a 30-30-30 Hard Reset of router
(8) Log into router DD-WRT, setting a new password when prompted
(9) Undo IP changes of (2) and log in again (Steps 2 and 9 are optional - not needed if you had always used default router IP)
Then I looked around in the GUI and began to reconstruct my other settings, WiFi, port forwards, etc.
All went well.AND, I then noticed that DD-WRT Mini seems to include some QoS functionality !SO, the $64,000 question now is :Do I need to change to Tomato (or to the VoIP-named larger DD-WRT build), or will the QoS functions of this MINI be sufficient ?
From what I have noted so far, the QoS page in MINI looks like it just might be OK.
BTW, I did NOT clear my NVRAM so far - Should I still do that if I stay with DD-WRT-Mini ?
