Thanks for posting the solution. FFFR.

I'll try to save others from Googling.

FFFR probably means For Fast Future Reference

or some variation of that.


Typo, sorry. It shouda bin SFFR, Saved For Future Reference.



No, it shouda bin "Saved For Future Reference." Abbreviations should
always be avoided unless they are so commonly used that almost
everyone understands them.

Okay, after some Googling, I fixed it! It appears to be some sort of
bug with DD-WRT on some routers. Under the DD-WRT web interface, I went
to the Administration tab, and then the Commands Tab. There I entered:
swconfig dev eth0 set enable_vlan 1
swconfig dev eth0 set apply
That fixed it! The only thing is I'm going to have to add that to some
sort of startup script or I'll have to enter it everytime the router
reboots (which isn't often anyway). Note: according to the forums, some
people had to replace eth0 with eth1. Anyway, thanks for taking the
time and giving me all the advice!

No problem.

I recently got a new router (TP-Link TL-WR841ND v9) and installed dd-wrt
firmware on it. Everything is working fine except two of the computers
on the network can't communicate with each other but they can both
communicate with other computers on the network. For example, I have 3
computers named Desktop, Lappy, and media-center. Media-center and
Lappy are both running Windows 8.1, and Desktop is running Windows 7.
Before I got the new router, all these computes could share files and
remote desktop just fine with each other. Now Desktop and media-center
can't communicate at all with each other (they can't ping each other,
remote desktop, or share files) but Lappy can communicate with both of
these computers just fine. Any ideas?


I've been experimenting and I've got some new information. I realized
that both the computers that couldn't communicate with each other are
both wired into the router. The Laptop (Lappy) was wireless and it can
communicate fine with both computers. So I decided to turn off the
wireless on Lappy and plug it into the router too. It then lost the
ability to communicate with Desktop and media-center. I unplugged Lappy
from the router and turned on the wifi again. Lappy could instantly
communicate with Desktop and media-center again.

So it appears to be an issue with the router. As mentioned above it is
TP-Link TL-WR841ND v9 running Firmwa DD-WRT v24-sp2 (12/22/14) std

Perhaps you should also check for a firmware update that'll permanently
fix the problem anyway, hopefully.
At the least, other bugs will be fixed!

BTW, I attached a board (and called it a "Feline Pedal Extremity
Excursion Management System") to a shelf to prevent "UnWanted Cat Foot
Movements" (cats knocking off cordless phone and TV remote).
