Strange internet connectivity problem
I'm having a connectivity problem I have never met before. I use a wireless router from Apple with internet cable.
Yesterday, my computer would be is no longer in contact with my router wi - fi. I get a message that the network could not be attached (I ran the Diagnostics wireless, but it's a whole lot of sense to me empty files). However, I also have a Roku, and which IS connected to the WiFi without problem. I completely stopped and restarted the computer, no joy. Reset the modem and the router, no joy. Still works with Roku, not with the computer. But the weird part is, I have Optimum Online, which allows subscribers to log-in to its hotspots, and it worked! I am connected Optimum wi - fi network on my computer right now.
So I don't know where is the problem! It is not the router, because this is related work with Roku and is not the computer, because it is connected and working with the Optimum hotspot. What gives?
Go to the Apple menu > System Preferences > network
Select a Wi - Fi connection in the sidebar and then click on the button "Advanced...". "in the lower right corner of the screen
In the list of preferred networks, delete the name of your Wi - Fi network
Click on the "OK" button to save that change and then 'apply' in the network preferences window.
Now, go to the Applications folder > utilities > Keychain Access
Make sure that "Login" keychain is selected and "All items" in the category is selected in the sidebar
Use the search field to find items that Keychain with the name of your Wi - Fi network and remove
Quit Keychain Access
Now try and access your Wi - Fi network

Hi, will try and give as much information as I can, so sorry for the long post.
I bought this new laptop in August is so very old, I connect to the internet with modem USB 3 G telstra and a cycle of 3 weeks he began to abandon the connection within 30 seconds approximately.
The blue LED on the identification of the USB modem still flash, it has a connection, but I would get the yellow explanation mark on the icon of internet connection in the task bar.
Now, the only way to recover the connection must close the connection of Telstra, unplug it, plug it back in and reconnect, a few times I have to reboot and will have to go through this routine 5 - 6 times and sometimes up to 10 attempts before I get a stable connection.
So first I thought it might be the USB modem, so I got a replacement of telstra, but made no difference, then I had a replacement sim card and still no luck.
Then I did a new install of Windows 7 and installed all the current updates, still no go.
I then bought a wireless router to eliminate the USB connection and still have the same question.
Sometimes it can be very frustrating trying to get a solid connection, but once it gets a good connection, it will stay connected for hours without any problem
I'm not an expert with computers, but can usually find a solution to problems of software, I have, but that left me speechless and I think I've covered most of the region to address this.
Thanks for your time.
Unfortunately I can't say anything on Telstra 3 G USB modem. Toshiba doesn't support third party hardware, software and does not offer any kind of support.
I put t know where you got this USB modem but I m wondering you didn't visit their store and test in functionality it bring your laptop with you. The people who work there could make inspection on site.
I also put t know why you have this problem at home. Your router is not known to us, but is there a difference when using WLAN secure or unlocked and without password?
I bought this laptop about 14 months ago and have had fairly consistent problems with internet connectivity. Initially, the problem occurred when the prompt "Choose your browser" would appear. After selecting IE or chrome, in a day or two, we would start to get the "limited connectivity" message. We have around this simply by avoiding the selection of the browser prompt, but would still have problems every few months, IE being told there was a communication problem with the DNS server.
We did the usual stuff: unplug the modem for a few minutes and sometimes he would settle the matter, but only temporarily.
Usually, as soon as the first problem arises, it would be just a matter of time until we could get no connection whatsoever. The only thing that could make it work again was a complete restoration of the system, we have done 5/6 times over the months.
In any case, it happened again, but this time NOTHING we tried before doesn't work. He started by see us full bars and 'connected', but being not able to open Web pages and now tells us that there is the usual problem of "DNS server".
Any help would be greatly appreciated as I'm not able to get a new laptop, or pay for repairs now.
I must also respectfully as advice or assistance request to explain as if you were talking to a 5 year old... This is NOT my fort!
Thank you very much.
Usually all the laptops with the factory settings and good connection LAN or WLAN can be used immediately for the internet. You have to just pick your favorite browser or install it also and just start using it.
In your ad I didn't understand one thing: what type of connection do you use.
Are you using a LAN or WLAN connection?

Recently, a problem came with my Windows Firewall. I don't know what caused the change, but I'll be surfing the internet very well, when a small bubble appears in my task bar that says: "your computer may be at risk. No firewall is turned on. "This has happened in the past, but when I clicked on the bubble to check before, my firewall is activated, so I simply rejected it. However, just a couple of days I noticed that when this bubble came, my internet connection would fail temporarily. So, when I saw the notice again once my firewall was not turned on, I checked. It seems that Windows Firewall turns itself off tension. I have no idea why he would do this. I manually turned it on again several times, but still it does.
I run Windows XP Media Center Edition and (to my knowledge) have all the service packs/updates.
Well, I asked a friend gifted in computer science, he suggests Spybot. I downloaded spybot, scanned my computer and found a Windows Firewall security override in my registry. Deleted Spybot, and now all is well again. This is a very quick and easy solution.
I can do the most sophisticated malware cleaning below to another date, when it is more convenient for me.

Hi, I have recently reinstalled my whole OS system on the desktop Dell vista (Windows Vista Home Premium SP1, Intel Celeron processor bits)
It is stating that "the network adopter"REALTEK RTL8101 FAMILY PCI-E FAST ETHERNET NIC (NDIS 6.0)"knows driver or hardware related issues."
My internet connection on the primary computer works fine. But between my router and dell computer internet connection does not work. I do not use wireless. The computer is directly connected to the router by ethernet cable.
What do you think is the problem? How can I solve this problem?
Go to the website of Dell here:
Then, download and install the drivers for the network card in your PC.
I wonder if anyone can comment on a subject that I have with a (a) wireless on my home network devices. The problem is that a Dell laptop knows slow or no internet connectivity using wireless at all. Sometimes 1-2 minutes to load one page, other times the message 'not able to display the Web page' dreaded. That's using Ethernet. I have another laptop (brand/model exact even) and it has no problem. I also have a Macbook Pro and other IOS from Apple (iPod/iPad) devices which are very good. Several connected Ethernet devices are very good as well. The laptop in question had no problem with my previoius Linksys devices, which are a BEFSR41/WAP55AG and a WRT-54GS v2. This laptop was the first day or two on the EA4500, but something happened that causes this problem. I had to add the WAP55AG on my network so my son is happy again, but my plan was to dismantle the other devices. Suggestions regarding what I can do to fix this are greatly appreciated.
EA4500 Firmware v.2.0.37
Laptop Dell Inspiron 15 w/Intel Centrino Wireless N1030, 1 x 2 bgn (2.4 GHz) + Bluetooth
Thanks for the suggestion. I tired who, but it did not work. I then called Dell and they found that the wireless adapter on battery power has been set to maximum power saving. Changed for maximum Performance and it's been very well. Fortunately there is nothing wrong with the router. Thanks again for the suggestion.
I bought a router Linksys WRH54G wireless yesterday, but I can not put in place. The problem is that my router is not able to connect to the internet. During the installation, while checking my internet connection wizard gives error - ' router is not able to connect to the internet. I have a protocol PPPoE connection.
My current setup with the modem is:
DHCP active...: Yes
Autoconfiguration enabled...: Yes
... The IP address: 192.168.1.100
... Subnet mask: 255.255.255.0.
... Default gateway. : 192.168.1.1.
DHCP server...: 192.168.1.1.
The router's default settings are:
user name... (leave blank)
I tried to enter the type of service as PPPoE via the method of configuration of the web browser and given the user name and password, but it is not always connect to the internet. I have a Beetel 220BX modem and my ISP is airtel.
You say that when you connect to your computer, through an ethernet cable, directly to the Beetel 220BX, you get the IP 192.168.1.100?
If the answer is Yes, then turn off your network and disconnect the Beetel and the WRH54G and follow these steps:
(1) your Beetel made the PPPoE connection for you, your WRH54G must be on "type of Internet connection" «DHCP - auto»
(2) your Beetel uses 192.168.1.x subnet, so you will need to put the WRH54G in a "local IP address" to 192.168.2.1
(3) turn off your network
(4) with an ethernet cable, connect the Beetel ethernet port to the Internet port on the WRH54G. If the Beetel has a USB port, do not connect anything to it. The power of your network. It should work.
Regardless of the browser that I use on my VISTA laptop, navigation stops... which means the laptop connects is no longer the DNS through the modem to broadband gateway to resolve the address of the Web site.
However internet is on and some applications that Act on the internet are connected and okay. for example: Skype

If after uninstalling the "Junk", the Internet connection does not work as it should, you will need to restart the operating system parts which get trashed by the process.

Despite the fact that I am connected to the internet through a broadband network, that the pc still shows that I am not connected to any network - why this?
If you could be more descriptive, it would be useful. I'll take a good guess on what you ask on...
Most of the time, according to me, you can describe what your computer is able to find a wireless router but the router doesn't send an IP (its normal function). He would say connected, but no internet connection.
This is usually:
1. your Internet service provider is down or your connection to it is broken. If this is the case there is nothing you can do about it. Call your service provider.
2 your computer network security key does not match the one in the router.
1 reset the modem & router. Follow these instructions precisely: http://canadiantech.info/?page_id=136
2. If that does not resolve the problem, you must remove this network from your list of networks to manage Windows 7. Then try to connect again using the network key, you know.
3. If this does not work, you will need to do a factory reset on the router and re - install the router according to the router set up instructions.
4. If after all the above does not correct the problem, you must replace your router.
