Posted: Wed Jul 31, 2019 21:43 Post subject: Linksys XAC1900 - Seems to work?
There doesn't seem to be any official support for this in any list I could find, but I found it was 'basically an EA6900 with a modem' (which I don't use or care about).
And it turns out... that's pretty true.
I was sick of the stock firmware and decided I was either going to brick it or toss it out; I flashed the EA6900 v40452 firmware and it appears to work.
I'm not sure how many issues are with dd-wrt, how many are with the hardware and how many are with my configuration from it not being supported, but for the most part it appears fine.
Teething issues:
I couldn't get my ipv6 tunnel working from the GUI, but manually starting radvd with the output of radvdump worked fine.
Web GUI seems very slow, up to 10 seconds to load a page, not sure why.
600/800MHz cpu speed toggle doesn't seem to do anything.
2.4 and 5ghz wifi appears to work, ethernet works fine, hasn't crashed yet.
Would you guys recommend any specific steps, like clearing the nvram to some known state or posting any certain logs?
Code:
Devices I have:
br0 Link encap:Ethernet HWaddr 14:91:82:34:B9:A3
eth0 Link encap:Ethernet HWaddr 14:91:82:34:B9:A3
eth1 Link encap:Ethernet HWaddr 14:91:82:34:B9:A5
eth2 Link encap:Ethernet HWaddr 14:91:82:34:B9:B5
vlan1 Link encap:Ethernet HWaddr 14:91:82:34:B9:A3
vlan2 Link encap:Ethernet HWaddr 14:91:82:34:B9:A4
Only unusual thing in dmesg:
br0: received packet on vlan1 with own address as source address
br0: received packet on eth1 with own address as source address

Ya, DD won't support any modem combo devices. Interesting find though; what is the FCC ID (or other regulatory IDs) and `nvram show|grep board` output? I'll update the EA6900 wiki with a note about this.
EDIT: I see this really isn't a single combo device, it comes as a kit with a separate modem.
The GUI sluggishness (and maybe also IPv6) is due to recent builds. The 'received packet...with own address' msg is pretty common too, though usually in bridged modes. I'd guess this is due to devices differences (like the modem) vs EA6900.
You definitely should clear nvram and manually set up, after you save a backup of it in case there are issues. Let us know how it goes. I'd also recommend a copy/paste of a `nvram show` output from telnet; into a spreadsheet is handy in case you need to sort/vlookup anyway in the future. I'd be curious if any params change that match `nvram show|grep -ie mac -e vlan -e port` in telnet. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

Just did an nvram reset && reboot, takes a few minutes to boot but it's working fine.
EDIT: tunnel is playing up, messing with it now.
Nothing I change in the ipv6 panel appears to 'go live' on the actual settings. sit0 is empty, no devices have the 2001:xx address assigned to them, etc.
You said the latest revisions may be having issues, is there a good stable version?
IPv6 is now working on the router, radvd still needs to be re-done manually it seems though.
Not sure if it was the reboot or the upgrade that ultimately fixed it, but that's one problem down for now!
EDIT:
dmesg:
ipcomp6: Unknown symbol xfrm6_tunnel_alloc_spi (err -2)
ipcomp6: Unknown symbol xfrm6_tunnel_spi_lookup (err 0)
uh-oh that seems bad, that looks like modprobe/insmod has exploded due to incorrect kernel config? I'm not sure if I'm using ip compression or not though to
know if that's fatal or just annoying. (I don't think I am though)
Edit2:
I eventually gave up fiddling trying to get my ipv6 to work, blew out all the settings, rebooted, put them back identically and now it works *grumble*
I have flashed the latest firmware on an XAC1900 to use as an access point. The only problem I have is that I can't seem to get gigabit ethernet working. It was working fine with my previous Belkin, so it's not the cables.

Do an `nvram erase && reboot` via telnet, manually set up. If it's still not on gigabit, check the VLAN page. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

I carried out the erase and reboot, after setting up gigabit still doesn't work. If I try to force gigabit in the VLAN settings it just resets to 100M. This happens for the link to my router, and my raspberry pi 4 which should be gigabit.
I followed the EA6900 guide (sort of) and my XAC1900 appears to be fine. I'm only using it as an AP with no features really.
If it's of any use to anyone;
Mine has a power switch, which I believe is equivalent to EA6900 v1.1 and it was running 1.1.42.162280.
I used the tftp utility and flashed FW_EA6900_1.1.42.161129_prod.bin because of all the talk about newer firmware being locked. Not sure if I needed to do this.
After flashing EA6900 firmware it then showed as "XAC1900 firmware version: 1.1.42.161129" in the "about" section.
I then flashed the initial 12-22-2013-r23194 via:
192.168.1.1 - Connectivity - Router Firmware Upgrade - Manual - linksys-ea6900-webflash.bin
It took and rebooted and dd-wrt was running. GUI was fast, everything appears to work just fine. Wifi is strong.
I then flashed 07-09-2022-r49467 the same way as above. (latest firmware as of this post)
