WRT54G Firmware Upgrade

Since WRT54G firmware upgrade from 2.2 (I think) to V4.21.1 I no longer have
access to my laptop files no matter what I try. Internet access is OK,
signal is very good, all firewalls have been turned off etc .. The OS is XP
Professional on both computers, the desktop is wired to the router.

Any help would be greatly appreciated.

Kind regards
Mark

Check on the "Security" page of the router configuration. Is "Filter Internet NAT Redirection"
enabled? If it is, it will kill access to local shares.

Also, if the shares are via wireless, the "AP isolation" setting on
the advanced wireless page will do the same thing. Make sure it's
OFF. See:

near the bottom of the list.

Jeff and Larry,

Many thanks for your prompt replies. Checked what you suggested and still no
access. It gets worse, since 'tinkering' with the router, now I have no
acces to the internet at all

I have a real problem with this, i.e, all was well until the firmware
'upgrade'. The file exchange desktop to laptop and vis versa collapsed since
the upgrade and the time it has taken so resolve this issue is simply not
acceptable. This is a simple, basis home 'network': - desktop to laptop, no
more. This is 21 Centuary and thing should not be that difficult. I am not a
complete computer idiot, I have professional IT background admittedly
somewhat 'aged' by today standards but I know (I think) what I am doing.

No doubt this can be resolved. My point is, it should not be so complex, All
worked perfectly well until the upgrade. I tried all Linksys software on
their website to help me to resolve this issue with no luck. I am not
blaming Linksys nor pointing my finger at anyone else, it may well be the
problem is my end but ... all was well until the upgrade.

Money is not an issue here (I have already lost a lot in time (I run a small
business from home and this has been an absolute disaster). I have no
problem buying another wireless broadband router, I simply want this
reselves soonest.

Apologies for this lengthy reply, kindest regards
Mark

No problem. Punch and hold the reset button for about 30 seconds on
the WRT54G and start over. My guess(tm) is that you've made some
assumption in the setup that isn't correct. Rather than try to find
it, it's easier to just start over.

For connectivity issues, go unto the "status" page and see if your ISP
is properly delivering an IP address. I can't tell from here whether
it's DHCP, PPoE, static, or whatever. Doesn't matter as you should
see real routable IP addresses on the status page. Once internet
connectivity is re-established, methinks the "share" problems will fix
themselves with a reset. The default configuration is fairly close to
correct (except for wireless security).

More commonly, the problem is in the configuration of the various
PC's. The easiest way to troubleshoot that is to take the wireless
part of the puzzle out of the picture. Plug each PC into the router
using an ethernet cable. Turn off the wireless in the PC if possible.
Now try it. If that works, wireless should also work. If not,
there's probably a "personal firewall", "Windoze Firewall", or similar
security product getting in the way.

>I have a real problem with this, i.e, all was well until the firmware
>'upgrade'.

That happens. The basic assumption is that all the settings are reset
to defaults after the upgrade. I've found that to be a good
assumption with most firmware versions, but there's no guarantee.
Punch the reset button to be sure.

>This is 21 Centuary and thing should not be that difficult.

I'll spare you my philosophical lecture, but simple products simply
don't sell. Features sell and they bring complexity to the table.
With the deluge of advanced acronyms and manifold protocols, simple
and wireless are oxymorons. I'm sympathetic, but don't expect much
relief.

>I am not a
>complete computer idiot, I have professional IT background admittedly

I think that might be the problem. No offense intended, but
assumption by those that know what they're doing has been a constant
source of trouble. I'm guilty of it myself. I "deduce" problems and
shortcut procedures. That usually serves me well, but not every time.
I just wasted 30 minutes activating a DirecTV receiver over the phone.
The first 10 minutes were spent trying to find the model number. The
next 10 were discovering I had forgotten to wear my eyeglasses when
plugging in the coax cable. Of course, it was in the wrong jack.
Extra credit for installing the smart card upside down. Like I mumble
often "Assumption, the mother of all screwups".

>No doubt this can be resolved. My point is, it should not be so complex,

Well, if it were easy, it would be no fun. Incidentally, if you
really want fun, try one of the alternative firmware installations for
the WRT54G. I recommend DD-WRT v23 SP3 at:
<http://www.dd-wrt.com>
It's not any easier, but with options to mis-configure, the
opportunities for entertainment value are endless. I probably spend
more time configuring my router than using it.

>All worked perfectly well until the upgrade.

Have you ever considered that this might be an unrelated incident?
It's a fair bet that your correct and that the update did something to
break your network. However, that's only one guess among many. I
deal with customers that often try to correlate events and symptoms.
I'd give them a 33% batting average, which is quite good.

Ok, let's try beating this assumption to death. What hardware version
WRT54G are you working with? It's on the serial number tag on the
bottom of the router. It makes a HUGE difference for firmware
selection, bugs, and setup.

>Money is not an issue here (I have already lost a lot in time (I run a small

Oh swell. Now we're in a rush. We'll I would normally suggest you
give me a phone call and we can work through it, but I'm late for a
free lunch and service calls, so not today please.

>I have no

Well, a service call from any reputable tech will cost about $50.
That's the same price as a new wireless router. My favorite of the
week is Buffalo WHR-HP-G54.

Good luck.

Jeff,

Once again many thanks for your most informative and helpful reply. You are
absolutely right in what you said. Admittedly I was loosing patience hence
some of my rather haphazard comments.

I followed your instructions and got things to work only to be followed
shortly thereafter by my Telstra supplied Motorola cable modem 'crashing'.
This was replaced today but now I have no wireless access from my laptop
even though wireless file sharing is OK. I will fix it though, just could
not help mentioning it.

Thank you again for your time and help, truly appreciated
Kindest regards
Mark

P.S. I enjoy your website

Y'er welcome. I got a bit carried away with the "lecture" format, but
I think I got the point across.

Crash? Well, it's not like a computah where the hard disk gets
scrambled and everything comes to a stop. Just reset the cable modem
and it should recover.

Well, two steps forward. One step backwards. Progress, I guess.

Masochist. It's a mess and desperately in need of reorganization. I'm
trying to learn a CMS (content management system) so I can make it
look garish and cluttered like the rest of the Internet.

Jeff,

I am embarrased to say I have not been able to resolve wireless internet
access with the new modem. To recoup the details - WRTG54G hardware version
2.2, firmware DD-WRT 23 SP3, Motorola SB5101 modem, desktop wired to the
wirelss router and laptop.

No issues with the desktop nor file sharing between desktop and laptop in
wired and wireless mode. However, cannot access internet from laptop in
wireless mode. Laptop wired directly to Motorola connects to internet but
will not if wired to the wireless router. It seems to me it is the router
that needs tweaking but I am at a loss where?

Can you assist please?
Kind regards
Mark

Jeff,

I have got it resolved. It was a simple matter really of not having the
Windows XP TCP/IP stack configured for automatic IP address . Thank you once
again, I have learned a lot from your posts

What's your opinion of the WLI-TX4-G54HP?

Any model/flavor you prefer better?

Application is duel. One being a poorman's P2P and the other being a mobile
for RV and traveling where the adaptor in the lap top(s) just don't make the
trip.

Family was at the beach last month and there was a free AP as part of the
rent if we could make the distance. The problem was half the lap tops could
only access the pay to play APs.
