Hello:
First, thanks for taking the time to read this post. Any help will be highly appreciated.

I have Windows XP Pro laptop with a built in wireless adaptor card. I have a Comcast high speed Internet which i connected to a Microsoft MN-720 router. Everything was working fine until now. When i try to connect to the wireless network Windows seems kind of stuck at the "Acquiring network address" stage. After a while it shows limited or no connectivity. When i connect using ethernet to the same wireless router everything is fine.
This phenomenon used to happen earlier too but a restart of the computer fixed the issue (not that i knew what the issue was) but now restarting the computer has no effect. For testing purpose i even tried connecting to other networks (neighbors network) which are open, the same thing happens limited or no connectivity due to failure in getting the ip address.

I will really appreciate if anyone can shed some light on this.

Hello,

Might want check that the wireless card is set to recieve IP addresses automatically.

Also, what model wireless hardware is it? If it is a integrated wireless feature like you explained before and you cant find the make, what kind of laptop do you have?

Thanks,

Carlitosway

Hello,
Thanks for your reply.

I have a Toshiba Satellite A25-S207. The detailed specification just shows Integrated Wireless (802.11b) LAN (Agere).

I think the wireless card is set to receive IP address automatically. Are there any other settings i need to make sure and how to do it?

any help is appreciated..

Thanks

True,

Since you said in the other column that this happened as soon as you put SP2 for Windows into the machine, try this fix.

This just might work since it's very close to the you have been getting. Also this appears to be a problem in regards to your Wireless Adaptor since you cant connect at any other sites.

Let me know how it goes,

I also had a Windows MN-720 router, I use Comcast High Speed Internet and I have Toshiba Satellite S161 (just got it in fact)...I had problems big time getting internet connections with the MN-720, it worked for the first month just fine, then "poof" like magic it stopped working, oh it powers up fine and wired traffic goes through it ok, just nothing wireless at all.

No settings were touched either - I know this as FACT.

So I finally got fed up with it and threw it out in disgust and bought a brand new Netgear Wireless router, been using this for about 4 months now without a single hiccup, not even once.

So check your manual, maybe double check your filtering settings (one time when first stetting up my laptops connection I accidentaly entered a wrong mac address so it blocked the laptop's connection, instead of allowing it), make sure you didn't make any forgetful settings mistakes like I did with the filtering, if that all doesn't work -- I say ditch your MS router and buy a net gear (or at least another non-MS brand).

by truespeak

Probably in future if nothing works then i will ditch MN-720 and go for a different brand. But in my case I oubth whether it is MN-720 thats acting wierd. I believe Win XP SP2 is the culprit. Ever since i installed Win XP SP2 i had problem with the wireless connectivity aspect.

As I had mentioned that i tried connecting to other open networks but in vain.

Is it possible that the Windows firewall is blocking your connectivity? If you have a real firewall, such as Zonealarm Pro, disable the windows firewall and see if that fixes the problem.

Good luck.

This is a tech. problem, in search of a solution.

It properly belongs in "Technical Q&A," not in "Discussions."

Please re-post there.

Thank you.

Well, like I said in one of my previous posts...deepsand IS saying thank you now......

the problem of Questions being mis-posted as Discussions?

Do you understand the difference?

If so, is it the case that you chose to ignore them, despite the fact that they here constitute community standards?

Or, do you simply like to make irrelevant posts?

Show me where the wireless section of Q & A is.
I requested a section for it under "New Ideas/Feedback". Did you not read that section?

Since a lot of things can be addressed from a wireless question, are you going to police all the areas until someone finds an area that YOU deem it fits in? You seem to be the only one telling people it's the wrong area.

It's funny that you rank over other people in this topic that have been helping and you've done nothing but criticize.

I am experiencing similar problem.
SP2 does not work with TRENDNET Wireless G-card.
Computer keeps rebooting by itself.
Removing Zonealarm didn't correct the problem.
However, removing SP2 fixed the problem. And I must also admit, without SP2 computer seems to be running a lot faster.

I have the same problem with whichever WAP I use. However all was working successfully until a few weeks ago - with SP2 installed. It's as if the computers are unable to access an IP address now, then reverting to Auto Private Address (limited connectivity). The problem is solved with a router but I'd like to understand why all was working well for months and then the problem occured.
