SOLUTION: 802.11n - Vista Getting IP Address but no Connectivity

I noticed a few threads in which folks mentioned their 802.11n adapters not working in Vista. Specifically cases in which you could get an IP address from DHCP but can not actually connect to anything.
I've found that the Linksys WPC300N drivers work fine.
You can find them at:
http://www.linksys.com/servlet/Satellite?c=LCASupportC2&childpagename=US%2FLayout&cid=1166859844332&packedargs=sku%3D1144763513196&pa gename=Linksys%2FCommon%2FVisitorWrapper&lid=4433213196B03&displaypage=download# versiondetail
... or just search their site for WPC300N Version 1.0 drivers.
After running the exe, it will create a folder named c:\Linksys Driver.
You will then want to go into Computer / System Properties / Device Manager, select the Broadcom 802.11n device, and then 'Update Driver'.
Hit 'Browse for driver software on my Computer' and then select, 'Let me pick from a list...'.
Then 'Have Disk' and browse to C:\Linksys Driver\WPC300N_20071105\Driver\VISTA (or wherever you put it).
Finally, select the WPC300N from the list provided.
Follow through with the prompts, and you should be good to go.

This did not fix the problem for wireless N networks. I could get an IP address before(and now), but not 300Mb/s connection speeds. It connects at first as 54Mb/s but then slows to a 5.5Mb/s. These drivers don't fix the problem. Are there any drivers that are not branded as Linksys that will work?

I recently switched from LinkSys to Airport Express 802.11n. I love it, but I can't get the Wii to talk to it so I can stream NetFlix. I've found MANY discussions on this, but it's still not clear to me. Anybody have a step by step so I can fix it?

Well, the Airport Express is also compatible with 802.11a, 802.11b, and 802.11g. If your Wii is unable to connect to the wireless network, I recommended changing the wireless security of your network.
Open Airport Utility, select your Airport Express and click Edit. Navigate to the Wireless tab and change your security from WPA2 Personal to WPA/WPA2 Personal. Then click Update on the bottom right.

AEX fails to get DHCP address, but works on DLink

Sorry for the long post -- I'm hoping the details will help you diagnose the problem faster in the long run.
My DLink router gets a DHCP IP address from the (Comcast) cable modem, but when I switch to the AirPort Extreme (5th gen, refurbished), it doesn't. It shows an autoconfiguration IP address of the 169.254 variety, suggesting that DHCP isn't working for the AEX. (Just fyi, my girlfriend's macbook can connect to the AEX and get 10.0.1.x IP addresses; I can ping the AEX over wifi.)
Airport Utiltiy shows a red number 2 with a single error indicating Internet failure to get IP address or something. The suggested solution is power-cycling the modem; failing that, contact the ISP. Contacting Comcast was amusing but useless...they gave me instructions for setting up AEX with a DSL modem -- twice -- without understanding my objection!
The AEX is configured for DHCP (not Static or PPPoE), and uses all stock settings (I did both a soft reset and used the Airport Utility to restore default settings...not sure if those two are the same).
I've tried power-cycling the router and cable modem numerous times, including leaving them off for 15+ minutes and leaving the AEX connected for 6+ hours. I tried using the DLink to release the DHCP reservation and then quickly switching the cable over to the AEX.
I read somewhere that resetting the "CMTS (cable modem termination system)" might help. I mentioned it to the Comcast tech support, but they didn't respond.
At this point, I'm not sure what else to try. It could be the refurbished unit is broken, but 95% of the time these sorts of things are configuration issues. (I know a fair amount about networking, but I'm new to Apple products so I could be doing something stupid.) I may try connecting the AEX to the LAN side of the DLink to see if it can get a DHCP address from that...but I'm clearly grasping at straws.
<whimpers>...Help?

Update: The AEX does get a DHCP address when connected to the LAN side of the DLink gateway. (But the AEX doesn't get one when connected directly to the cable modem. Yet the DLink gets a DHCP address when connected to the cable modem.) So...??!?!!!

I cant copy a youtube link to my email. i get the address, but no link.

i just switched to firefox. i have not had this problem before. i go to youtube, highlight the link, hit ctrl and c, then go to my email, where i hit ctrl and v, but it wont come up with a hyperlink.

This is the second time I've upgraded from FF 5 to FF 6.02 and both times I lost the ability to make desktop shortcuts by dragging the favicon to the desktop. I need the feature.
Also, I'm sick of getting bugged to upgrade from FF 5 to 6. I'm not upgrading my other computers until this problem is fixed.
I'm on a recent Dell PC with 4GB RAM, 1TB HD with lots of space, fully upgraded Vista Business, no extensions, only common business programs.

No Hyperv Virtuals get DHCP address - but Physical Host Can

HyperV Server 2012 Core on a dedicated machine on local domain.
Machine connected directly into local network that has a DC running DHCP.
None of the VM's can get a DHCP Address from the server. Even if i set static addresses still they cannot route anywhere, cannot even ping the HyperV server they are sat on but other local machines can!!!!
The physical host cant ping the
The physical HyperV server has no problem getting a DHCP address or any routing issues, nor do any of the other clients on the local network, including another HyperV server running server VM's
What ive tried so far
Deleted Virtual Switch and removed the NIC from the virtual hosts in HyperV Manager- then re-adding new one.
Put in a different network card
Removed Physical host from Domain, renamed machine to different name and re-joined
Used different IP addresses for the Physical host
Reloaded the HyperV server from scratch and created new VM.
Ive had HyperV previously running on this machine without problem, so now i cant see why i cant get it running again.
Anybody have any suggestions on what i can try next, im all out of ideas.

Hi Fulgent,
I am assuming that , the hyper-v server have two NICs , one for host and the other one was configured as an external switch for VMs .
If the VMs can not access the dhcp and local network , please try to delete the external switch then uninstall the Physical NIC in device manager and click " scan for hardware changes " to reload it.
Try to create external virtual switch for VMs again .
Any further information please feel free to let us know .

Wifi clients get an address but cannot access network

Hello,
I have setup 1131 AP's which connect to a wlan controller 2106
The dhcp server is a windows 2003 server. All equipment is connected to inside lan, no vlans have been configured.
AP's are normally associated and wifi clients get an ip address from the windows dhcp server.
Strange thing however is that when you are connected to the wifi, you cannot access anything. Dns is configured properly and even when you enter an ip address of a website, I cannot reach it.
I have no idea what can be wrong. Is it that we use internally a 172.16.x.x /16 range and the wlan controller uses 172.16.2.x for both ap as management interface and the dhcp scope is 172.16.5.x /16. Same subnet.
Anybody a clue?
Thanks and regards,

Atheros card gets an address but can't do anything

My wireless card is able to get a dhcp address from an AP, but after that I can't do anything. Pinging most anywhere just hangs, and trying to ping the gateway comes up with 100% lost packets. It is, however, the proper gateway.
Other connections to APs of the same model are okay, and other computers are able to connect to this AP. Mine has been able to connect to it in the past, but I'm not sure what change caused the problem.

Try removing:
nat (outside,inside) source static NETWORK_OBJ_192.168.80.0_24 NETWORK_OBJ_192.168.80.0_24 destination static inside-network inside-network no-proxy-arp route-lookup

I know it's not a browser problem because I can use a different Airport signal and open them fine.
Anybody have any ideas?

Works just fine for me, in fact I clicked your link and paid my Amex bill <- thanks!
Seriously though, have you cleared the cache in your browser. I used Safari and the site first switched over to some home.americanexpress site and then once I logged in it switched to another site.
What browser are you using?

Receiving an error message when connecting to internet saying: windows cannot find "address" but it connects anyway???

The error message that appears when trying to access internet says that windows cannot find "address" and asks to make sure it was typed in correctly. It continues to connect but is a hassle to deal with the error message each time. Any suggestions?

What is the ip address you are getting on the Vista Computer..?
Click Start >> All Programs >> Accessories >> Command Prompt...A black box will appear(Command Prompt)...In the Command Prompt window type ipconfig and press 'Enter'...Look for Wireless Network Connection IP Address , Subnet Mask and Default Gateway...
IP Address should be 192.168.1.x, Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1 (assuming your router is 192.168.1.1)...
If you get the above mentioned IP Address, Subnet and Gateway Address then you should ping the Gateway, type ping 192.168.1.1 and press Enter...If it gives you request timed out then disable any firewalls, security softwares on the computer...
If you get 4 replies then type ping 4.2.2.2 and press Enter, if you get request timed out, then you need to upgrade your router's firmware...If you get 4 replies then type ping yahoo.com and press Enter...If you get replies for Yahoo then you should get the Internet after adjusting the browser settings...
Adjusting Browser Settings : Open an IE, click Tools >> Internet Options, then delete all files, cookies, history, forms...Goto "Connections", make sure Never Dial a Connection is checked, click on LAN Settings and make sure all the options are unchecked...Once you are done click on O.k...Close the IE and re-open it...
If yahoo times out then provide static DNS on your LAN Connection...
Click on the Start button >>> Settings >>> Control Panel >>>Network Connections- Right click on the icon for Wireless Network Connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the Following DNS Settings' Preferred DNS 4.2.2.2 Alternate DNS - 192.168.1.1>>Click on Ok button to Save and Click on "Close" on main Properties window...You should be able to go online...

RRAS 2012 With DHCP Works, Cannot Get Static Address Pool To Connect Completely

Hello Forums Users:
I have set up RRAS/DA 2012 successfully incorporating my AD DHCP server. Every connection works and I see all networks that I have VPN tunnels set up with, which is totally cool. However, I want to assign remote VPN users IP's from a
static address pool - and while the setup completes without issue and the client connects, I can see absolutely nothing. No good pings, no connect to Lync client, Outlook, etc. etc.
I am OBVIOUSLY missing something but have no idea what that is. Do I need to add something (and I really have no idea what that "something" is) to RRAS config so the static address pool (192.168.40.0 in this case) has the same access as
the AD DHCP pool does?
Thanks again for taking the time to check this out and comment.

Bill:
Thanks for the reply.... yes, the idea is to free up a pool of IP's large enough to accomodate all 170 staff. Our current 192.168.2.x DHCP hands out 150, but I need to plan for DR/BCP when other locations (about 110 users) remote in when their
location goes dark.
I already have VPN tunnels between the main locations and a VPN user can see ALL of them when it gets an IP from DHCP. Are you saying that I have to add routes to all the routers/firewalls to accomplish this?
Or would I use IPv4 Static Routes? A network I'd like access to is 192.168.14.0 /24. Would the route look like any of these? Sorry it's not clear what I would use as the gateway (192.168.2.1 is the RRAS server network gateway, 192.168.2.6
is RRAS IP)
Destination Net Mask Gateway Interface
192.168.14.0 255.255.255.0 192.168.2.1 LAN
192.168.14.0 255.255.255.0
192.168.14.254 LAN (
(.254 is the remote gateway)

Itunes using Airport Express 802.11n and Remote app no longer staying connected

I'm running Windows 7. I find that my Remote app either keeps dropping Home Sharing (unless I toggle Home Sharing off/on in Itunes) or if it finds my library it cannot open it through the app. I can play music through my Airport, but it's the remote app that can't seem to connect with my iTunes. I should add that the remote app has the same breakdown on both my iphone 6 and ipad mini 2. So it's not the app, but some problem along the line (Airport express? router? Itunes?) Any suggestions?

OK, thanks for the info.
You'll need to jot down a setting that the AirPort Extreme (AEBS) is using in order to give the AirPort Express (AX).
Open AirPort Utility, select your AEBS and click Manual Setup
Click the Wireless tab below the row of icons
Jot down the setting that you see for Wireless Security
Close AirPort Utility
Hold in the reset button on the AirPort Express until you see the amber light begin to blink more quickly and then release.
Temporarily, position the AX near your AirPort Extreme and connect an ethernet cable from your computer to the AirPort Express
Open AirPort Utility, select the AX and click Manual Setup
Click the Base Station tab below the icons to name your device, establish a device password (write this down) and adjust time settings
Click the Wireless tab
Wireless Mode = Join a wireless network
Wireless Network Name = Exact same name as your AirPort Extreme wireless network
Enter a check mark next to Enable Ethernet clients
Wireless Security = Exact same setting as your AEBS that you wrote down
Wireless Password = Same password that your AEBS network is using
Confirm Password
Click Update at the lower right and the AX will restart. You can close AirPort Utility and disconnect the ethernet cable once you see the message that the settings have been saved to the AX.
After 30-45 seconds, you should have a green light on the AX. Now you can move the AX where it is needed and power it back up again. The ethernet port on the AX is enabled in this type of configuration, so you should be able to connect an ethernet device and connect. You may need to restart the device and/or the entire network to get everything synchronized.

TS1702 Supercam Pro update.Just downloaded update 24-05-2013 and now cannot connect to DVR.Entered correct http address but not connecting,anyone else having same problem?

Supercam Pro,latest update yesterday 25-05-2013.Now cannot connect to my DVR.Anyone else having problem with this update,worked perfectly before???

The OP is correct, I have done many tests. With IOS6 there appears to be a dns issue in some cases with IOS for both ipad(2) at lease (my wife won't let me upgrade here v1) and the iPhone4s in my case. Pretty easy to diagonse, I wish Apple would fix it.
1.) I use a Juniper 5GT wireless firewall and all of my other devices (many apple, ipad, MBP, iMAC,3 ipods etc) are fine: Not ipad2 or iphone4s running IOS6
2.) after upgrade nothing worked. narrowed it down by messing with dns (I have my own dns server)
3.) Strange thing; dns works over MiFI (Verizon) and Carrier
4.) confirmed that it is a dns and not network issue.
-down load free tool called ping-scope-lite. (obviously you need to turn off wifi to do this)
http://itunes.apple.com/us/app/ping-scope-lite/id431500107?mt=8
turn on wifi
- ping Level3 dns server 4.2.2.2 or Googlesdns servers 8.8.8.8 or 8.8.4.4 these worked.
-now ping by name google.com or ipchicken.com
- try others; same result.
Apple did say that they would give me another iphone 4s: I just wasn't sure that would fix my issue. I tried downgrading to 5.1.1 but I got an error saying my device wasn't able to do so (tried even blocking itunes from contacting Apple) I whis this could be fixed. I did even have it working using my own dns server but now I can see that my phone over wifi isn't even trying to make a dns request now.

AEBS Gigabit 802.11n FW 7.2.1 - OS X 10.5.1 Port Mapping HELP!!!!

Hi
I have a AEBS with Gigabit Ethernet upgraded to Firmware 7.2.1. I am running OS X Leopard 10.5.1 and I am unable to successfully forward ports. Every time I query a port that I believe to have mapped successfully it appears closed using canyouseeme.org.
I have followed numerous instructions, but they all seem to be instructions for Tiger, I'm wondering if a setting has been missed. I have successfully assigned a static IP address to my machine but still the port appears to be closed. I do run the Leopard firewall using specific applications option (the third one), but I have also tried it with the firewall off and it still hasn't changed anything, the ports are always closed.
So now I'm pretty much stumped. Has any one actually managed to get a setup similar to mine working, with the ports being open? All advice appreciated.
Thanks

How to enable 802.11N extended network and WPA2 Personal Security?

Hello,
I have an aiport express 802.11N, using Radio Mode 802.11N (5Ghz only) and set to "allow this network to be extended". At the same time the wireless security is set to "WPA2 Personal" (and the key defined). This router is also hooked up to the internet as the main bridge.
On the other side, I have an airport extreme set exactly the same way from a security standpoint (WPA2 Personal) and for this one, the wireless is set to "extend a wireless network".
Both routers have their light green and my computer is wired to the airport extreme. The computer gets its IP address from the main dhcp server and I can FTP to any ftp site; I can ping any machines on my network;
Now the problem:I can not browse the internet nor ping any website. Http traffic is completely blocked.
If I reset the security to none on both routers, I can then access the internet without any problem.
Has anybody been succesful with this configuration and what am I doing wrong?

You need to download and install the AirPort Extreme 802.11n* Enabler for Mac. But it will cost you --- $1.99. Order it from the Apple Store:

WRT120N 802.11n problems

Hello!
I just bought a new WRT120N Router. It worked perfectly wired and wirelessly.
But my old laptop burned, and the new one came with a Atheros AR5B93 Wireless Network Adapter, which is Draft-N compatible.
The laptop connects to the router fine, but using only the G type. When I set the router to use only 802.11n, i get a message from Windows, like: "Windows was unable to connect to the network."
Please help me solve this problem, because the N configuration is much faster than the old G.
Thanks,
edydotmail
Solved!
Go to Solution.

How you come to know that the computer is connecting with G type....?
Try to adjust the settings on the router..Open the linksys setup page,Change the Channel Width to 40MHz only,Wide Channel to 9 and Standard Channel to 11-2.462GHz and click on save settings...Under the Advanced Wireless Setting,Change the N Transmission Rate to 7-65 Mbps,disable the Frame Burst..Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"... Now,check...
