Hi,



I changed WEP key in my Linksys BEFW11S4 to the value created by its website
(http://192.168.1.1) generator. I remember that alphanumeric string I used
to generate WEP key was quite long. After this I saved this setting. It was
last time when I was in contact with router.



Now I can't access to website of router. Neither router nor Wi-Fi is working
L. Only switch is working correctly.



I tried to reset router using reset button - holding it even for 1 minute -
but it didn't help.

I suppose the router is in strange blocked state. I can't ping its default
IP address (192.168.1.1). But there is one interesting thing - I scanned its
IP using port scanner and only one port is opened: 110. This port is used by
POP3 protocol.



What should I do to restore proper state of router? Now it's just not
functioning.



Here is described similar problem:

Thanks for any advice.

Did you try accessing the router via a wired/ethernet connection?

You mentioned creating a WEP key in the router. You didn't say that you set
the same key on your wireless card in the computer.
If, for some reason, you need to reset the router, there's usually a little
hole in which you insert a pin to reset all values to factory default. This
will also erase your logon settings and any other changes you made to the
router.

Can you connect to the router by CAT5 cable? Make any changes this way to
keep connectivity.

Anytime I change WEP settings or MAC address filters I have to reboot
the BEFW11S4 to get the network up again. Don't reset it (that will
lose all your settings), just pull the power adapter plug out, count to
10 and plug it back in.

Did you update the WEP key in your wireless card's configuration menu?
If not, you need to use the exact same key in your wireless card in order
for it to communicate with the router.

Actually I don't remember this key so I can't access via wireless.
Nevertheless it's obvious that it should be possible to do it via
wired/Ethernet - but it is not working :-(

You might be able to access the router's config. menu and see the
inserted encryption key. If so, simply copy it then paste it in the
wireless card's config. menu. If you're unable to do so, you can always
reset the router to its default settings (no encryption, etc.) and start
over.

As I wrote before I tried to reset router but it didn't react.

It looks like BEFW11S4 is in the "not responding state" it means that even
reset button don't work.

Have you tried the old unplug it for an hour, repower it and hold down the
reset button, using a pen tip or paperclip end to securely depress it for
about 45 seconds?

Then I'd say it's dead. Gee, that's go perfectly with one I have that
got hit by lightning, and now only the WiFi works (blew out the switch
chip). 8*)

I have just tried it. Router is still not responding.

What can you say about port no 110 (on router IP) - it's opened. Is there
any possibility to use it for accessing to BEFW11S4?

Don't think so. Port 110 typically used for POP3 traffic. I doubt that the
router would be listening to that port for management activity.

The good news is you should be able to buy a WRT54G for about $60 - net of
rebates.

I walked a customer through resetting their BEFW11S4 V4 router. I
think you have the V2 which is different. So far the 3 problems I've
seen with long WEP key locking up the system seem to be with V2. My
guess(tm) is that an ultra long WEP key overscribbles something in
NVRAM and hoses the firmware.

Anyway, I guessed that maybe you have to apply power AFTER holding
down the reset button. I had them pull the plug, stomp on the reset
button, apply power, and hold it like that for 60 seconds. That
seemed to work. However, the customer was not very good at following
instructions and had to do it something like 4 times before it finally
decided to reset.

If really desperate, you might wanna fire up a TFTP client program and
upload a new copy of the firmware. I usually don't like desperation
moves until you've tired all the various combinations of reset.

No clue on why port 110 should be open or what good it will do.

I have BEFW11S4 ver.4 router too.

I'm really desperate.

Do you think low temperatures should cause restoring correct state of this
router? If yes, I could put it in the freezer (guarding it against water
first) - maybe it will erase memory (NVRAM). I hope it will not destroy
switch which is still functioning.



Any suggestion appreciated.

I don't think that will work or help. Clearning the NVRAM will
probably also clear the firmware. My guess(tm) is that it might be
like some other Linksys products, where the tftp server firmware is
seperate from the operating bios firmware. There's almost nothing
useful on the FCCID web site:
https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/ViewE...'PKW-BEFW11S4V4'
I was hoping for a block diagram, but couldn't find one. Looking
inside, there's no jumpers, battery, or obvious test points that can
be used to reset or clear the NVRAM.
https://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve...
No clue on the identity of the original manufacturer.

There is a 2x10pin header near the front panel that was probably used
for product testing and initial NV loading. On my unit, I think (not
sure) that the connector is missing. I suspect that it can be
re-flashed with this connector, but I have no inside information on
the connections, proceedure or required software.

It's interesting that the RF chip listed is a client chipset, and not
an access point chipset. Marvell Libertas 88W8000/88W8300.
http://www.marvell.com/products/wireless/libertas/88W83...
So, I guess they do their own MAC layer processing externally.

I have some doubt that the router really has port 110 open. Try turning off
the router and trying your port scan again. Maybe some other device is
responding to the same IP address.

You are right. I have just checked it.

So my router isn't responding at all :-(

Hey guys if u are having this problem,
go to your comand prompt i.e ms-dos
type ipconfig while your router is connected via ethernet cable.
you'll definetely see the IP address for your router.
