Are you running this on a 32 or 64 bit system?

This squashfs image appears to be compressed using LZMA. Since LZMA was not 
officially supported until squashfs 4.0, the failure to extract is likely due 
to yet another vendor-specific LZMA hack.

If the vendor has a GPL download available for the device, it may include 
unsquashfs that will unpack this. Since you didn't mention exactly what product 
this is, I'm investigating some D-Link GPL code that appears to have been made 
by the same people.

This firmware is for ZyXEL ODM router "Freeport"(for Russian internet provider 
Rostelecom - review (in Russian) - http://ivbox.ru/viewtopic.php?t=97534 Chip - 
Ralink rt3050/52. There is no GPL code in public for it. 
But the same (I think) squashfs compression was used - in ZyXEL Keenetic router 
( http://zyxel.ru/keenetic?t=3427) firmware -BFW.5b Edition. Here is GPL code 
for previous edition - BFW.4 - 
http://dl1.web.zyxel.ru/001/Keenetic/firmware/zyxel_keenetics_gpl_v.1.00_4_D0.ta
r.bz2 , but developers didn't use this "sly" LZMA compression in previous 
edition - I think it's their "know-how". I can copy FS from router if it'll 
help to find solution.

Here is Zyxel Keenetic firmware with the same compression -

Here is my solution for EA6500v2(squashfs with LZMAv2)

I meet the same problem. Extract the original firmware and build it without any 
modification. But the script said that the file size is greater than the 
original one.

I change build-fireware.sh line 58 from "-comp lzma" to "-comp xz" and 
successfully build a run-able fireware.

I seems that Linksys EA6500v2 fireware is build with xz(AKA LZMAv2).
