In build v3.0-r62778 the SSH terminal session prompt is suddenly totally different from what it used to be, and oddly different from the usual in Linux:
Router/Version: Linksys MR7500

Kernel: Linux 6.6.116-rt29 #4610 SMP Thu Nov 20 14:08:38 +07 2025 aarch64
Previous/Reset: R61848 - No reset
Mode/Status: Gateway device - NAS/Local FTP/Samba - OpenVPN server - DNSCrypt
Issues/Errors: NO wan connectivity. Saved firewall settings missing in GUI.
- Using R61848 GUI I backed up my current configuration before flashing R62778.
- After reboot all appeared normal, even had USB support; however, there was no internet connectivity.
- Checked WAN status in GUI. Setup page showed it was enabled, but physical port was not active.
- Decided to the reset to factory defaults and manually reconfigure.
- Went to <ADMINISTRASTION><Commands> to copy revised firewall config before reset. Firewall dialog box was empty.
- Was this a GUI issue? Opened SSH session to view firewall from command line and look for errors in log files.
- As you can see above I wasted zero time going back to R61848. Nope, Nope, Nope! I'm not jumping in a rabbit hole today.
FYI - After the partition change and reboot R61848 was exactly as I left it. I did not have to restore my saved profile or modify any settings. Been up almost 4 hours since then without issue.

Reverting back to r61848. I am looking for a stable build for nas.

I saw a mention somewhere that with this build, dd-wrt has switched to nftables. Is iptables deprecated then, so that scripting using iptables has to be redone? Or is there some way that iptables and nftables commands will both work? _________________ On 61465: 3x Dynalink DL-WRX36, Linksys MX4200v2, 2x MR7350.

You can use
Code:
$(nvram get IPTABLES)
or IP6TABLES to get the correct binary for your router. If it supports nft it will return the nft version. _________________ Qualcomm-Atheros

Code:
┌─[✓]─[root@R7800:192.168.1.1]─[~]
└─$(nvram get IPTABLES)
iptables v1.8.11 (nf_tables): no command specified
and output of all my iptables rules are duplicated : iptables -vnL
old builds like 62606 does not produce output of this command
$(nvram get IPTABLES)
on build 62606, rules are ok and show some traffic counted...
may consider return to 62606 until nftables water is cleared out... _________________ Atheros

The prompt hadn't changed after reboot. Maybe that is because the quotes had somehow been stripped in /tmp/root/.profile.
The new prompt is OK for now. It may be useful one day and one gets used to it, so I didn't try harder to get the old one back.

Netgear XR700
DD-WRT v3.0-r62778 std (11/21/25)
Errors: Router spat the dummy after flashing r62778 above. Had to re-enter previous configuration settings manually. Restore of previous config. settings also sent the router back to default state.
Wired VLANS refused to work no matter what angle i tried in the last two days. Most other features seem to work. But i stopped at VLAN issues and went back to r62606 for now.
