okay i juz bought a d-link router...i followed step by step on installing the router...and the computer tat i used to install the router works perfectly fine with the router (both wireless and cable). But when i tried to use other pc to connect to the router, it will attempt to connect and shows this message " Windows couldn't find a certificate to log you on" . What should I do to fix this problem ?? will installing the router's driver into every computer that im gonna use help ? isnt tat gonna be so mah fan..

I got this DIR-300 Router. I've never received "Windows couldn't find a certificate to log you on" this message... could u post the screenshot?

Also, you don't have to install driver in every computer....

Never seen this problem anyway. Perhaps there is something not right with that particular computer. Have you try with yet another PC? maybe borrow friend's or neighbor's notebook and try.

i got 3 other running on wireless in my house...all showing the same message...bah headache... =/

what version of windows are you using? which web browser are you using? have you tried using other browsers, e.g. Firefox?

If u connect other machine using wireless, wat security u set in ur router to use the wireless

all 3 using xp and i use both i.e. and firefox yet is still not working...but the problem is the message showed up when i was trying to connect to the router...=/ .. i use open WEP

I guess you mean you are connecting the wireless card to the DIR-300.

Looks like this could be some problem with Windows settings itself. Tried googling it but could not find any solution so far. Shall let you know if I found any solution.

yeah was googling for it for a while now...but seems like i couldnt find a solution yet but will post it if i do find any juz in case any1 face the same problem as me in the future...

If not mistaken it appear "Validating Identity" or "Windows couldn't find a certificate to log you on", rite?

Ok, it's not the DIR-300 Wireless Router problem. It's actually a setting in Windows Wireless Connection, that's needed to be disabled.

What u need to do is, open your Wireless network properties => click the wireless network tab => select your preferred wireless network, then click Properties => click on Authentication tab => make sure u uncheck Enable IEEE 802.1x authentication for this network.

It works for my customers. So I do hope it will work for all of u.

CHEERS!!!

Or u can download my manual => [attachmentid=361023]

thanx a lot stcpg4u...ur step actually works and my problem has been solved...if any1 else is having problem with their windows couldn't find a certificate to log u on...here is the solution for u...and again thank stcpg4u =D CHEERS!

Hi there, noob here. Recently i own a Dlink wireless ADSL2 + router (DSL-2640T) encounter constantly connection loss and sometimes need to restart pc 2 or 3 times (during online) then can be connected. I m using wired. This does not happen when i used my streamyx free modem (DB102 ADSL modem 2/2+). Izzit my Dlink failure or need some setting to do. Please advise. Thanks.

Hi, i am facing a problem wif DIR-300 router too... Whenever i online for few hours later, the ready LED (READY LED) will stop blinking and my internet connection all stop. Wat is the problem and how to solve it??? I only can re-online after i restart my router....

Download the latest beta firmware (currently 1.03) from DIR-300 product page and flash your DIR-300 with this firmware.

WARNING: Do NOT upgrade firmware using wireless connection. Please use a wired connection when performing upgrade

You may also consider put the router standing up using the bracket. This gives better air flow to reduce heat.

Juz update the firmware, hope this will really solve my problem... Thanks to bro jolmy~

After download the firmware 1.03, how to flash pls?
Is the procedure of flashing included in the download file of firmware 1.03?

The firmware is a .bin file. Use the web configuration of DIR-300 to flash it. It's in Maintenance > Firmware Update. Browse the file and click apply. The process takes about 2 to 3 minutes usually. Do not power off the DIR-300 during the process.

If that doesn't work, flash it to DD WRT instead After all, it's about the only reason why I would buy a DIR 300 nowadays...

Well, it works fine in my case. The 1.01 firmware supplied with the router is problematic, which leads to the 1.02 beta and now 1.03 beta.

Sometimes the hang happens because of overheating (perhaps). But not anymore since I place the router on standing position using the bracket.

For your case it's most probably a unit problem. Take it back to whoever that sold u.

Yeah, i agree with Jolmy. It doesn't always happen.

Sorry, may i know wat is DD WRT stands for?

anyone know what is the square button at the side of the dlink dir 300 use for ?

it's definitely not a reset button....

That is for WPS, Which is the source of the problem of this thread

If you disable WPS, remove the wireless profiles on windows and readd it.
Then you will find that the 802.1x things disable.

Also another way is to use WAP
That one also get the problem solve and safer also

WPS is applicable only for WinVista users anyway. However I did try connect my friend and cousin's Vista powered notebook and do not have any problem.

If you set the DIR-300 to WAP mode, you will need another router for NAT to work. From my understanding, the DIR-300 will only function as an Access Point while the 4 wired ports will only function as a switch.

Who say that???

DIR-300 is a Router lah...

oop, is WPA (Not WAP)

Using that encryption is better alot.

If you do realize, there is a setting that disable the router mode into just an Access Point. I thought you really mean WAP (wireless access point)

Yes.. WPA is a lot better. WPA2 will be preferred anyway. In my case I enabled both WPA/WPA2, because my cousin here need to connect his Sony PSP, which only supports WEP and WPA, but not WPA2.

i just signed up here because i wanted to thank you for this. i had the same problem and searched on google for a solution and came across this. THANK YOU SO MUCH!
and this prob occurs with Windows XP. my cousin's laptop which had Vista didn't have a prob. hehe.

what is WPS actually?i've googling about it but stil don't understand.anyone can simply descibe it?when do we use?

How do you flash it to DD WRT ???????????????

AND WHAT IS DD WRT.

dd-wrt is a third-party (not the router's manufacturer) firmware, which was originally develop based on linksys WRT54G firmware. maybe thats why there's the 'wrt'. however i dunno what the 'dd' stands for. here's for further info.

well, i'm not a dd-wrt sifu. but to me, dd-wrt is essentially a firmware that will transform ur cheap, ordinary router to a stable, feature rich one. for instance, these r the things that i like in my dd-wrt (there r many other, however not within my interest), which can be hardly found on most home-class routers.
- nocatsplash : force everybody using internet from ur router to view a certain page 1st.
- support hotspot system : chillispot, wifidog, sputnik.
- static dhcp - pre-set the dynamic ip for ur users based on their mac. by using this, it is easier to control access, usage etc for different kind of users (based on ip range).
- mac filter - up to 128 users (most stock firmware supports <30)
- ur router can operate in multiple modes: ap, wds, client bridge, repeater bridge. these modes r useful if u want to expand ur wireless network
- universal repeater mode - can repeat any wifi signal, without any configuration (or knowledge) on the original signal source
- tweak ur router - increase transmit power (to extend range), overclock the cpu, select which antenna to use etc
- port forwarding
- QoS
- ddns
- url filtering

i bought a dir-300 yesterday and have successfully flash it to dd-wrt v24 rc5. its kinda difficult if u r a noob. check the guide here.

however for routers like linksys wrt54gs/gl etc, u can flash to dd-wrt using the same way as upgrading ur firmware.

he he finally... i managed to connect my dir-300(router) with PCI blw-54mf(repeater)....

Any know this DIR-300 can be use like repeater ?

I looking for this DIR-300 link(lan cable) to my existing wifi router to extend my wifi signal. Does this work ?
