I didn't find 7510 of V2 in www.tp-link.com and my country http://www.tplink.ca/en/ as well.
The software of V1 should be unavailable for V2 I think.
For your question, could you provide more detailed information such as your topology?
And to remotely manage the device, do you achieve it through WAN port or SNMP?

My region: India.
I'm using Spidigo broadband.
My TP-Link 7510 connects to the Spidigo Base wirelessly using operation mode: AP Client Router: WISP Client Router

I have connected the TP-Link to a Netgear router (WGR614v10) in its WAN port.
This way I get WiFi access.

TP-Link is on IP: 192.168.1.254 and Netgear is on: 192.168.2.1.

I can't even find my current firmware anywhere online: 3.13.0 Build 140730 Rel.39812n

So, is there any way to backup my current firmware from the TP-Link modem somehow?
Just to be safe.

Send an email to support@tp-link.com for help ;)

I'm afraid that there is no access to backup the firmware.
Why do you want to backup the firmware? If you are afraid the settings on your 7510N be modified, you can backup the configuration file instead of firmware.
Login the web management page, navigate to System Tools > Backup & Restore to backup the configuration file.

As for your topology, I'm puzzle of the settings. Here are two ways for optimization and they provide the same function:
1. Configure 7510N in Client mode, with DHCP off. Wired connect the WGR614 in router mode to LAN port of 7510 with DHCP on.(Recommended)
2. Configure 7510N in AP Client Router mode, with DHCP on. Wired connect the WGR614 in AP mode, with DHCP off.

Hi,
Thanks for your reply.

Yes, I have already backed up my config settings. My current configuration is working fine.
It is already set to what you recommended:
1. Configure 7510N in Client mode, with DHCP off. Wired connect the WGR614 in router mode to LAN port of 7510 with DHCP on.(Recommended)

My 7510N freezes every few days, and I need to manually reboot it.
So, I was looking for a firmware upgrade hoping that it would fix my problem.

I saw on 7510N V1 firmware page here:
http://www.tp-link.us/download/TL-WA7510N.html#Firmware

that the latest firmware had fixed a similar freezing issue caused due to a memory leak.
So, I'm looking for a similar solution for my 7510N V2.

For now, I'm using a VBScript which runs every few hrs and detects Packet loss (using ping).
It reboots the router if there is failure. But this is just a temporary solution.
Was really hoping for a new firmware to fix it permanently.

In fact you don't need to using the VBScript, TP-LINK provide a function like this called Ping Watch Dog. It's under the System Tools tab.
But as you say, it's the temporary solution. What you can do is to find out if there any problem in your topology and wish the staff of TP-LINK view this thread.

Ok, I'll check out Ping Watch Dog.
I'll take your suggestion and check out my topology again and tinker around with different settings.
I also just contacted TP-Link by email. Let's see what they say.

But thanks a lot for your guidance. Really appreciate it.

I have the same problem but with V1 of the tl-wa7510n. The antenna gets frezzed and stop working, then resets itselfs even if ping watch dog is off or On. Hope TP-link solves this issue. :(
