Jul 11, 2011

I have a realtek wireless usb adaptor on my hp desktop that was working until I took it out of the usb on the front of the tower and plugged it into a usb on the back of the tower. Now I can't get internet at all even if I move it back to the front! My network doesn't show up under connections. Both the playstation 3 and the netbook are picking up the wireless signal from the router.

Realtek PCIe FE Losing Connectivity In Windows 7 Home 64-bit?

Mar 23, 2012

I am having an intermittent problem with my network connection dropping out for no apparent reason.When it drops, I still see the lights blinking on the NIC card, but cannot pass packets even to the router.Windows does not report the connection or the cable as disconnected when this problem is occurring.The problem will persist until I disconnect and reconnect the CAT-5e wire, or disable and re-enable the NIC.As soon as I do one of those 2 things, connectivity immediately returns (and works for another hour or so).I am running a legitimate copy of Windows 7 Home Premium 64-bit on an HP Pavilion.All of the latest Windows updates and the latest firmware drivers are installed.My ethernet connection is a wired Local Area Connection with a static IP address, gateway and DNS.The IP address, gateway and DNS settings are accurate and work for several other computers here.[CODE]

Realtek PCIe FE Losing Connectivity In Windows 7 Home 64bit

I am having an intermittent problem with my network connection dropping out for no apparent reason.When it drops, I still see the lights blinking on the NIC card, but cannot pass packets even to the router.Windows does not report the connection or the cable as disconnected when this problem is occurring.The problem will persist until I disconnect and reconnect the CAT-5e wire, or disable and re-enable the NIC.As soon as I do one of those 2 things, connectivity immediately returns (and works for another hour or so).I am running a legitimate copy of Windows 7 Home Premium 64-bit on an HP Pavilion.All of the latest Windows updates and the latest firmware drivers are installed.My ethernet connection is a wired Local Area Connection with a static IP address, gateway and DNS.The IP address, gateway and DNS settings are accurate and work for several other computers here.The Network Interface Card is a Realtek PCIe FE Family Controller (VEN_10EC / DEV_8136 / REV_05).NIC Power Management, Energy Efficient Ethernet, and Link Down Power Saving are all turned off.On the NIC, ARP/Large Send/IPv4,TCP,UDP Checksum/NS Offload, Flow Control, and are all on.

Receive Buffer Size on the NIC is 64Kb (512 buffers). Receive Side Scaling on. 128 Transmit Buffers.Interrupt Moderation is turned on. Magic Packet features are turned off. Optimal Performance enabled.NIC Speed and Duplex are set to 100mbps Full Duplex wherever possible (automatic was also tried).802.1X authentication (EAP or PEAP) is disabled. Auto connection logic is disabled.Connection routes through two switches into a Belkin router; other devices on same networks unaffected.Much of my data is stored on a Network Attached Storage device, with UNC shares mapped to drive letters.Other Windows, Mac and Linux devices connected to the same NAS device have no problems staying connected.When the issue occurs, I can't ping the gateway, do DNS lookups or pass any packets as far as I can tell.I have tried swapping out the CAT-5e cables for other cables and even ran them through a cable tester.

Network fixes I have attempted from the OS level so far include:

~ Switching the dynamic port range to start at 10,000 and run for approximately 54,000 ports

~ Systematically reviewing every running service to make certain that only the essential ones are on

~ Disabling all NIC stacks except Client for Microsoft Networks, IPv4, File and Printer Sharing and Comodo

~ Attempted connections with Comodo turned completely off and its NIC driver disabled

~ Attempted rolling back the RealTek driver to an earlier one from the same family and device line

Using netsh I have tried the following settings:

~ netsh winsock reset catalog
~ netsh int ipv4 reset reset.log
~ netsh int ipv6 reset reset.log
~ netsh int tcp set global rss=enabled

Wireless Adapter Not Connecting To Router On Start-up?

Jul 3, 2011

I have a Toshiba Equium A200,(from new some time back) however, i have had it updated with new 500mb drive etc! I also some time back installed Windows 7 home. At first all was well, then a few months ago i noticed (upon star-up) that the network adapter was not connecting to my Belkin router? The Network & sharing centre tells me that it is connected, although the icon on the bottom toolbar shows a yellow triangle & reads No Internet connection? I have to go through the same process evrytime to get connected, which usually takes approx. 5 mins That is to follow the Network/share centre's troublshooting? I have updated the adapter Driver, yet still the problem exists?

Linksys Wireless-G Notebook Adapter 2.4 Not Connecting To Internet?

Jun 15, 2012

For quite some time my linksys wireless g notebook adapter hasn't been connecting to the Internet at all. I go to my Internet options and my house's Internet router doesn't show up. I remember a long time ago I was clearing space on my computer because its and old one and it runs slow Because I don't have much memory and I might have accidently deleted the linksis progam / installation. And I have no way of re-intalling it. I think the only way of re-installing it is using the linkage disc but I lost it in some boxes packed in storage.

Protocols / Routing :: Trying To Connect Wirelessly To BT Home Hub Via A USB Wireless Adapter?

Mar 14, 2011

I am trying to connect wirelessly to my BT Home Hub via a USB Wireless adaptor. The homehub works perfectly and I have other laptops in the house connecting via the wireless networkHowever, this is the problem. The Wireless connection status shows as good but packets only being sent and not received. Therefore when I load Internet Explorer, I get WebPage Not availableI notice that my IP address is starts with 169 and researching forums suggests that this is the problem and it should start 192? I have tried all sorts of things but simply cannot get this resolved. If I plug the HomeHub into the laptop directly, the connection via the ethernet cable works fine.

Connecting To VPN Without Home Wireless Network

Apr 17, 2011

I recently set up a VPN on my home computer. I am wondering if it is possible for me to connect to the internet via the VPN without also being connected to the internet via my home wireless network? Right now, whenever I disconnect from my home wireless network, my connection to the VPN will also cut off. This is a problem because should my connection via the VPN ever be interrupted, my home wireless connection would then "take over" the connection, and the eb sites I'm visiting would then be able to see my real IP address, which makes having a VPN pointless. I'd like to have it so that if my VPN connection is interrupted, I will simply not have internet until the VPN connection comes back.

I am running Windows 7.

Linksys Wireless Router :: Connecting E310 To WRT54GS With Trendnet Usb Adapter

Aug 29, 2011

Trying to connect my Dell Dimension E310 to my Linksys WRT54GS with a TRENDnet wireless N USB adapter.  It sees the router, it connects, I show strong signal strength, but get a "limited connection or no connection" error back from the router...can't get on the Internet. If I use an Ethernet wire and connect it to the router, it can set up a wireless connection with the machine, I can unhook the hardwire, and I'm good to go.  But every time I reboot, it won't connect unless I set it up with the hardwire first.  Impractical.All other devices attached to the router are fine and connected to the Internet.  How can I get the router to maintain the settings for this new connection so it will connect wirelessly when I reboot?

Linksys Wireless Router :: WRT610N 5ghz Xbox 360 N Adapter Not Connecting

May 30, 2013

WRT610v2 running latest 360 sees both the 2.4 network (ssid = network1) and the 5.0 network (ssid network2) when it does its scan.Initially, xbox showed network strength for 2.4 network at 3 out of 4 bars and 5.0 network at 1 out of 4 bars.Connects to 2.4 network just fineWon't pull an ip address and reports "Not connected" when I select the 5.0 network.I tweaked the wireless settings per some suggestions I found in this forum and now it shows the 5.0 network at 4 out of 4 bars signal strength. Also turned security on and off and xbox 360 reported the changes in security on the 5.0 network.So the xbox 360 is definitely seening the 5.0 network. and can tell if it is running WPA2 or not..If it can see the 5.0 network and recognizes what security and network type (infrastructure) is set, would would stop it from connecting to the WRT610n router and getting an IP address? No mac filters or firewalls are set and, again, connects just fine and gets an ip address if I select the 2.4 (network1 ssid) instead.

Home Network :: Connecting Tv To Internet Via Laptop Wireless

Apr 9, 2011

Just got an HDTV, has a load of fancy internet stuff, but only has a wired connection and I can't put my router in this room, and would rather not have to run a wire up from downstairs.

I'm guessing there is a way of connecting to the wireless on my laptop in this room, connect the laptop to the tv via an ethernet cabe, and bridge the connections or something so that my tv gets the internet from the laptop. That's gotta be possible, no? When I try it tho, the connections bridge, but the tv says "Gateway is not connected, gateway address wrong or unavailable". Using auto IP.

Windows XP Not Wirelessly Connecting With Linksys Adapter

May 2, 2012

I have an HP Pavilion desktop computer running Windows XP Home Edition. It used to never get internet wirelessly for some reason until one day i played around with it. I don't remember how but I got it to go online and it worked ever since. Just recently i have moved from my previous home and have finished setting up both of our computers. The Vista (the one i am using to write this) is an Ethernet connection and is having no problem connecting to the internet. Although, the XP for some reason will not connect to the internet. The adapter will find the network but when i type in the WPA2 it tries to connect but i think it times out or something. I have tried several solutions and none have worked. My father has a Toshiba laptop and he is currently having no issue with connectiong wirelessly to the internet. Our old verizon router stopped working when we attempted to set it up after the move, so verizon came and istalled a new one. It is secured with a WPA2 code whereas our older one was secured with a WEP code. I think it might be a problem with either the router or the wireless adapter itself (which is a Linksys Wireless-B Network Adapter). Also, when i logged into my router manager thing, I noticed that under the network, it said the XP was an inactive Ethernet Connection and not Wireless.

Here are some of the XP's specs:
Hewlett-Packard Pavilion
Intel[R] Pentium[R]
3.40 GHz
0.99 Gb of Ram

Realtek RTL8188CE 802.11b/g/n - Unable To Connect Through Wireless

Sep 26, 2012

I have just purchased a new laptop (HP Pavilion G series) for my studies at university. The wirless works fine when I am connect to my network at home, but I am only able to connect to the university's network when an ethernet cable is plugged in. Everybody else I know, who has a similar setup to myself has no problems connecting to the network without the ethernet cable and I was curious as to why this might be.

I am running on Windows 7 and the wifi adapter is a Realtek RTL8188CE 802.11b/g/n

As I say I am quite a rookie when it comes to computers

Realtek RTL8188CU Wireless USB 802.11n Slow On Windows XP?

When I install a micro-wifi-usb 802.11n with "Realtek RTL8188CU" on a old notebook with Windows XP I get maximum 1.5 to 2Mbits/s. Though installed on a newer notebook with Windows 7 I get 30Mbits/s.Other wifi-usb, Cisco Linksys WUSB100v2 does work on that Windows XP machine at 30Mbit/s, but the dongle is much larger The router Cisco WRT320N is just 5meters away and I always have excellent signal strength.I tried some other drivers without any luck. On the site of Realtek I don't find any driver except with some letter diverence at the end of RTL8188CU, which I also tried.

Toshiba L305d-s5895 Not Connecting To Wifi Nor Reading Adapter

Jan 28, 2011

I am using Toshiba Satellite L305D-S5895, with Windows 7 Home Premium.My laptop has been running beautifully since I updated from Windows Vista to Windows 7 Home Premium in Fall 2009. However, today the laptop has not been connecting to the wi-fi. It could not read the Atheros wireless card built into the laptop, and the all the network settings showed was the Ethernet adapter (realtek). I tried restarting and shutting down the laptop but it still did not read the wireless card (though the wireless light on the laptop was on, indicating that the wireless is on).

Then, after 4 hours of leaving the laptop shut down, the wireless started again. However, a half hour later it was down again, with the same problems already stated. The light was on and the card was not read. During my time online, I did manage to download the driver update from Toshiba website (Atheros Wireless LAN Driver for Windows 7 (32/64). I tried to install it but I received error messages, including: I tried again but I still received this message, but with a different file: I have no Ethernet connectivity and I need to use the wi-fi.
