Strange Probook 4520s & 4530s issue with internal wifi «limited access»
Sorry for the long post, but I wanted to tell you everything that I have done so far.
We run all HP’s a few various Probook and elitebook models, and with all of my 4520s models and a few 4530s, which run win 7 pro 64 bit, I am having the hardest time getting it to connect to the internet from our internal network. I have done everything from running ipconfig /flush dns, /registerdns /release and /renew, resetting the winsock, resetting the tcpip stack, disabling ipv6 via registry, updating drivers, to re installing win 7 from scratch.
Now after I reset the winsock and did the registry edit to disable ipv6 and restarted the computer it seemed to connect, but after another reboot it came up with limited access again. These computers have no problems connecting to our guest or any other wifi network. So I restarted the dns and dhcp services on our server, and made sure there were no errors and that the ip pool wasn’t consumed, and ran ipconfig /all on all of the systems in question which in most cases pull all correct dynamic information ip, subnet, dns & dhcp, which they do. I have also tried using static ip, but still doesn’t give me internet access.
So here is how the wireless is setup now. We have a cisco small biz wap -N for our internal network, which uses our internal dns and dhcp servers, and then for our guest network, we have a linksys g router using its internal dhcp server and setup to use googles dns servers.
So, I changed and added the wireless g router in each building, because when we had the wap’s using a vlan for both wifi networks, i would have to power cycle our 4410n wap every other day. and with the setup now, I haven’t had to power cycle the devices for a good month now.
At first I thought it might be the channels so I was playing around with them which seemed to work for as day, but then reverted back. So now I am really stumped, and HP just kept telling me what I had already had done.
So can anyone give me a hand or have any other ideas for me to try, I would greatly appreciate it.

I have the same issue with our ProBook 4530s and corporate wifi which is running at 2.4Ghz and authentication mode is WPA2-EAP. The wireless profile is handled with a Group Policy and works for every other model we have -Dell Latitudes, but the ProBook 4530s will connect and then ultimately lose connection. They can connect to the guest wifi without issue. I finally gave up and don’t use the ProBook 4530s for anyone that needs wifi access, only those that are wired all the time. Not an elegant solution, but I was tired of beating my head against the wall.

did you try getting the newest wifi drivers from HP and removing and installing the drivers? bios updates, windows updates? edit: im seeing posts where some one did mention near the end drivers maybe at fault, but all in all very common issue it appears. http:/ Opens a new window / h30434.www3.hp.com/ t5/ Wireless-Internet-Home-Networking-e-g-Windows-8/ HP-ProBook-4530s-problem-with-Atheros-AR9285-802-11-b-g-n/ td-p/ 859619

I had this and had to replace one of the wireless access points. (if it’s only one) Other than that. Are you sure the dhcp-scope has an outside dns? like your isp- dns and or google 8.8.8.8 as last resort?
What your story says is that you can possibly rule out issues with the computers themselves since they work on the guest net. (do the guest net have any encryption by the way?) Then it could be your network setup or simply hardware failure in the network. If it’s not hardware, then you are left with the network setup. DHCP, DNS-forwarders etc. Can you ping internal machines? your DC?
OP Daniel9483
Yes I tried all of that ethan, I was really thinking it might be interference from both of the networks, because now my 4520s still show limited access, and now my 4530s is showing as having internet access but yet can’t ping external or access websites. I wish my situation was as easy as yours inkmaster, but everyone here use both wired and wireless, and since we just refreshed all of our computers I cannot get any more right now.

do you have HP support then if they are recent? id go to them and say. «make them work».. or whoever your reseller was..
This may be a very odd suggestion, and I have seen this. Have you checked the wiring for your internal network? It could be that there is a loose cable. I had a wireless problem at my work that was plaguing my team in which after doing checks on the wires, turns out there was a loose cable.

Yes, I tried this when I tried using a static IP used both google’s and opendns dns server ip, so i was thinking of replacing the a access point, but with all of my other systems, which all have the same wireless card work just fine, so if it was the access point, I would expect most of my systems to have issues, not just a select few, right?

Do the laptops work if you install with a 32-bit version of Windows 7? Do you have access to a USB wireless dongle? It may be useful to try one to figure out whether the issue is with the machine, the wireless network infrastructure or with the in-built hardware and/or drivers. To confirm: when you said that they have the same wireless card is it the exact same model of card?

Yes usually the simplest things go over looked, but that was the first thing I checked, even swapped out cables and switched ports just to see if that would help. just strange how only some would have an issue while the majority have no problem.
Reminds me of a problem we had with a batch of Dell Vostro laptops. A few questions: Did they ever work right, or was it a problem right out of the box? Have you tried them on another network — local Starbucks, at home, etc? We finally had to get Dell out to replace the wireless adapters in a half dozen laptops with a different model. It was a run of defective adapters.
Ideally you would need to troubleshoot this and narrow it down one step at a time. Eliminate one by one your suspects. «Limited connectivity» in Windows is not really a totally relevant error message — although in most bog standard setups it might mean simply that the router is not connecting to the internet. 1. Eliminate DNS issues — set the machine(s) on static dns (Google dns or something) and see if this solves it. 2. Eliminate your dhcp setup as a suspect — set the laptop(s) on static IP addresses (and DNS, gateway etc.) 3. Do the laptops have internal LAN connectivity when this happens? Can you ping your server(s) or another machine — by *IP address*. 4. Did you get to try another usb wifi dongle — and did it work? If that didn’t work either, it is getting really interesting. I would remove any HP «helpful» networking software. I like to see the forest from the trees — just the Windows basic utilities and the driver are enough from where I’m standing. 5. Rarely, pretty much any antivirus package can go bonkers and cause this type of stuff. I didn’t notice in your OP if you have tried uninstalling your antivirus (and run winsock and TCP/IP resets immediately after — as when things go bad, the antivirus can corrupt the networking stack). 6. As the others suggested — did you try connecting to a wifi AP from a different maker — ideally with full WPA2 enabled — not in unsecured mode? You need to be clear what works and what doesn’t work on the machine when this happens. Does the machine have a full IP address assigned to it when it happens? Can it ping internal hosts by IP? Can it ping a DNS server externally by IP? If it does, then it can’t be a DHCP issue. However, based on what I’ve read above, it smells like a driver issue. I remember having several Compaq/HP laptops a while ago with this diabolic Atheros chip — and the version of driver shipped on them would drive me insane with similar issues. In the end, after Googling for days, I found an obscure version of said driver on some Australian HP website, or something — which worked fine. I have solved the same problem several times on similar Compaq machines ever since with this driver. However, finding the right driver for your machine might not be easy. Also — there have been cases when particular wifi chipsets were simply incompatible with certain routers from certain manufacturers — and short of the manufacturers either releasing new wifi drivers, or new firmware for routers — not a lot that can be done.

Chris, Yes they did work before on our internal network, and yes they work fine on any other network, even works on our guest network. seeing how we only have four 4520s’s I was trying to work around it, but the other spare laptops i have are older than dirt, so I need to get these working, but its stumping me since all of my other laptops, which are either 4540s and 570b probooks and the rest desktops its very strange, and I just don’t get whats going on because I’ve tested signal strength, did a wifi network survey and nothing was out of the ordinary.

I’m thinking about exchanging the Wireless-Network Card in my Probook 4520s, because of the low data throughput.
So I searched for a while for a 5 Ghz supporting Card and found out, that I’m only able to get «whitelisted» Cards working. So I looked at this page:
These Cards might be all, that were used in the 4520s. Mine (according to the device-manager) is the Broadcom 4313 802.11b/g/n. This thing only supports 2.4 Ghz. Now I looked at the list for a 5 Ghz supporting Card. I think the 802.11A/B/G/N WLAN Intel HMC minicard 572520-001 could run on 5 Ghz, because I read, that A is only listed with 2.4/5 Ghz Cards. Also I read, that 2.4/5Ghz cards have 3 antennas, but on this card I only the the slots for 2. Is this right? And would this Card run in my 4520s?
