I had the same problem with a D-Link 802.11n.
Does your wifi to the DHCP or a server behind it?
I have a linux server and use the wifi just as a bridge.
As soon as i manually configured the IP setting on the HP all is working fine.

@nixhox, look in your router settings for somthing called DHCP.

First, ensure that DHCP is enabled.

If DHCP is enabled, you then need to check the DHCP settings for the items sent to your connecting device. The 2 most important of which will be your DNS & your Gateway IP's.

Most routers of this type will pass the DNS straight through from the auto discovered DNS provided by your ISP, and they will usually set the Gateway IP to that of your DSL port on the routers commus line connection.

Some however allow you to set them manualy (Mine does this), so i have to ensure that my DNS address is set to either my ISP's primary DNS (Or in my case, my own as i run my own DNS servers) and my Gateway needs to be set to point to my public, or bridged IP connection in the router.

Iv'e always found that routers with built in Wi-Fi are more trouble than there worth, so what i always do with any set up i do, i get a no WiFi router, and a seperate WiFi access box, and i do all the onfiguration myself, thatway i know exactly which connection/packet is going where, however it's not for the novice and you do need to know a little bit about how TCP/IP and networking in general works.

9 times out of 10 however, you can be pretty certain that it's the DHCP server either not handing out an address or the correct details, or your TS is not getting told the correct DNS details.

Start->Run->cmd click ok then type

ipconfig /all

and press return. That will display the parameters that your touch smart gets from the router, check things like the IP address, gateway are in the same range as your router. EG:

if router is on 192.168.1.1 then TS sould be 192.168.1.somthing, if it's 169.x.x.x iv'e often found that thats beacuse it's not getting a DHCP address at all.

There's no one single way to sole issues like this, so all i can really do is give you some ideas & pointers, but if you get stuck feel free to ask, i'll see what i can do to help.

i have problem with tp link router please send me seeting with wifi wateen .net

i reset my tp-link TL-WR642G and i dont know what happened i can not login whit default ip 192.168.1.1
its show 169.254.44.188 on network connection .....what should i do ?

please help me,

kou

thank you brother , i will try

kou,

hi bro

default ip is 192.168.1.1 and i try to set my ip 192.168.1.xxx but it doestn work...

it always automatic show 168.254.44.188 if i dont configue ip
i dont know how to Enable DHCP
because i ever set DHCP Enable when i can log in finished

what shoud i do bro ??
sorry for my English bad
kou,

I recently purchased a Linksys WRT320N router that I am only using as an access point. When I have it configured for 5Ghz my HP Touchsmart doesn't recognize the wi-fi network. When I configure the Linksys for 2.4Ghz it recognizes and works fine, however I am not getting the full speed.

Anyone have any clues as to why the TS will not connect at 5Ghz?

Shawty said: As far as I'm aware the TS can't do 5ghz on it's WiFi port, I could however be wrong. Anyone care to verify, i have mine on a wired connection (Much much better, esp with GB ether) so I can't test it.

Is this a hardware issue or software?  I thought 802.11n was suppose to be 5Ghz and since the TS is advertised as being 802.11n capable then I am confused as to why it shouldn't recognize this frequency.  I'm not a whiz on this but thought the 5Ghz was suppose to be a stronger signal and faster so am a little perturbed that the HP which is advertised as 802.11n compatiable isn't able to recognize this 5Ghz frequency is a little bit of bullshit.

 Can anyone shed any light on this?

Many sites do not open through routers/wireless routers. There are few steps to follows to allow all pages to open.

1. Update the router with the latest firmware from the manufacturer's site. Please make sure the firmware and version are matching during the update, else the router may be completely damage.

2. Try to search the MTU size in the router. In BSNL(INDIA) you can lower te MTU to 1450~1465. At 1450 almost all pages will open. You got to make a hit an trial an check, at which MTU all sites opens best.

As i Read there is problem in the TP -link router.

Dear user frankly speaking tp link routers are one of the best routers i have ever seen an the wireless ones are simply great. Yeah ! there are few things that we have to do manually.

In the PPPoe connection of the router click on ADVANCE and there you will find the MTU. change the MTU to 1450. save the details and then reboot the router from system tools page. Then open those sites that do not open.

Wireless frequencies are just the speed the actual wave travels at in terms of cycles per second.

The fact that 5ghz has a five in it doesn't mean it's a stronger signal. The signal strength actually comes from how much voltage is pumped into it at creation time, the higher that voltage is the further it carries.

The frequency of the signal however does efect it's penetration power, and a radio signal with a shorter wavelength will penetrate further through thicker/denser materials than a longer wavelength will.

This to some people does appear to be a stronger signal, beacuse a 5ghz will happily go through walls/doors/buildings etc etc that the 2.5ghz one wouldn't

The actual data rate available, is a product of the wavelength, the power and the modulation speed super imposed over the carrier.

All data based radio systems are a product of a data signal (Generally audio based) super imposed over a carrier, this carrier is then modulated onto the wave, and the power of the wave energy carries it.

The wave frequency may be 5ghz, but the actual bandwidth may only be half or a quarter of that, depending on how the modulation is done, and at last count there are 1000's of different modulation schemes, some based on frequency, some based on amplitude, some based on both.
