Is it possible to use a Nexxt Solaris 300 with DD-WRT? Nexxt is not on the database...

Here I have some pics from the inside of the router as well as it's FCC ID#:

First of all, remove the heat sink and take a decent close-up picture of the chip underneath. Also, a better close up picture of the chip in the corner.

I, but mainly the devs, need to be able to read the model numbers written on the chips themselves.

Hi. I have one of these routers and stock software is crappy (as usual). I had to remove a iron-soldered heatsink and thermal paste in main chip to take the pictures.

Main chip is a Broadcom BCM5357C0KFBG

Hope y'all can help me


Regards from Venezuela.

I can't find the flash size but when the manufacturer's firmware is only 1MiB it is not looking good. DD-WRT needs at least 2MiB for very limited features and 4MiB for most routers. VPN support requires at least 8MiB.

The good news is that a bunch of routers with the same SoC are already supported by DD-WRT. Search for Broadcom BCM5357C0 on wikidevi. The issue is that the supported ones all have at least a 4MiB flash.

I found this in Wikidevi http://bit.ly/2Jez5Pn. Same Nexxt brand. Model Xtender 300). I checked stock firmware and size is 724 KB, so, I think that flash size for Solaris 300 is same 4MB.

What firmware should I use to start the tests?

Try this file. It is based on the generic nv32 mini file, K26. I chose a stable build from earlier in the year.

You use the file at your own risk. I have not tested it in any way.

I have no idea. You could try flashing it via SSH or telnet. Heck, you could even try serial. No idea on login info for that particular router. Default ip address, etc.

I use PuTTY for telnet and SSH. Serial I use Br@Y's Terminal or even PuTTY. Serial requires opening up the router and connecting wires to the board (possibly soldering).

Can you help me updating my router using Telnet? I already opened Telnet 23 port, but I don't know neccesary commands to update it to DDWRT cooked version that you gave me.

Neither I can't find any tutorial to do it in english or spanish, my natural language.

Need backup here. Thanks in advance.

That is just a generic error. I can't make it load from the GUI, that is not going to happen.

Try SSH or telnet.
These are from the dd-wrt wiki but the info is a good start anyways: https://wiki.dd-wrt.com/wiki/index.php/Telnet/SSH_and_the_Command_Line

Most router firmware use telnet/SSH with the password method.

Hello again. I'm facing a real internet blackout. I've tried several times updating this router, including Telnet and SCP, and I can't.

I entered in it via Telnet, typed 'help' and just gave me reduced options:

CLI> help
reboot restart thread time nvram syslog debug splx mbuf ifconfig ping ipnat fw login envram wl wlconf et

Additionally I discovered that memory system for this router is 16777216 bytes, heap 8085256 bytes, Free 7489276 bytes and Max 7436380.

Can somebody help me installing it? I'll appreciate it a lot. Greetings
