Bizarre WiFi Connectivity Issue; Self-Assigned IPs, Static IP Doesn't work

The short and sweet of the problem: Macs/Apple Devices are pulling self-assigned IP addresses when connecting to a Linksys EA6900/AC1900 router.
Here’s the detail: I am working at an office with 1 Airport Extreme and 1 Linksys EA6900/AC1900, both are configured for Bridge Mode and both use WPA. DHCP is being handled by a Watchguard XTM5 series firewall.
When Macs (and often iPhones) connect to the Linksys (on 2.4 or 5Ghz) they get a self-assigned IP address. If you enter a manual address you still do not have any connectivity. However, if you connect to the Extreme you will instantly get an IP address, and if you switch to the Linksys your DHCP address will carry over and you will retain connectivity. This problem does not happen to the Windows machines in the office- they all connect to all base stations without any issue. Total users on the network range from 5 to 20 WiFi users at any given time plus and AppleTV (also affected).
More info: When there are between 5-10 people in the conference room for a morning meeting the Macs will all revert to self-assigned addresses (even if they were working before). The workaround has been to connect to the Extreme, but there are occasions when this occurs that the Extreme will also not seem to pass the DHCP addresses from the firewall; addresses become self-assigned and you lose all internet. To make matters more odd, this behavior seems to really only affect the network during business hours; after hours the Linksys works pretty much normally and any device can connect without issue.
Things I’ve done: Run Wireshark and located a number of rogue devices that were handing out overlapping DHCP addresses. Identified machines that were ARP storming and removed them. Expanded the DHCP pool so that we aren’t running out of addresses and confirmed that we had enough by checking the logs.
More things I’ve done: Used Netspot to check signal strength and channel overlap and isolation. I have mapped the signal strength by location and we have strong signals to the various locations (the Linksys AP is 7 feet from the conference room). I have checked that the firmware is the most recent version.
I can’t find any logical reason for the Macs (and pretty much only the Macs/Apple devices) to not be picking up DHCP info through the bridge mode devices. I would tell them to get another Extreme but they are going to be deploying a Cisco Meraki system soon and I suspect that this problem will persist since the Linksys was put in place because the last AP displayed the same behavior with the Macs picking up self-assigned IPs. Affected Macs range from 2010 era MBP and Air to 2013 MBP and Air and they are running OSX 10.8 through 10.10.
As for the history of this network, I just walked into this company and know very little about how well it worked before, but apparently it has always been flaky according to the staff.

I agree that something isn't right; I am going to cut over DHCP services from the Watchguard to the newly deployed OS X Server tonight and see if that changes anything.
On the other hand, faulty DHCP server/client settings doesn't explain why applying a static IP still leaves you with no connectivity. I think that clue is also fairly important but I can't figure out what would be blocking connectivity on a static IP setup.

Self assigned IP Address, wireless doesn't work

After upgrading to Leopard I keep getting "AirPort has a self-assigned IP address and may not be able to connect to the Internet." when I try to connect to the wireless network. Thus, wifi does not work at all. I've researched it best I can and it seems to be a problem with the router assigning an IP address to the mac, but why didn't this happen in Tiger? However if I play around with it for awhile it will randomly start working, but the same method doesn't fix it everytime. It also works fine in bootcamp. If I physically plug into the router, it works fine. This problem didn't exist in Tiger at all.

Follow-up:
On the two laptops, I finally managed to get on line by switching to a different wireless access point, on a different modem. I surmise that the communication between the Macbook DHCP client and the modem/router's DHCP server is less than 100% effective. Looking at the modem/router, I could see that all of the Macs had active connections. But, instead of showing the names of the Macs, the page showed a star (*) for each Mac. I had to compare Mac addresses to verify the connections. The MAC address, of course, is hard-wired into the computer's network interface. It appears that either the DHCP client didn't know what question to ask when it broadcast for an IP address, or it couldn't interpret the answer. Except in the case of the iMac, which worked perfectly.
I upgraded the MacPro last, since it is my primary machine. Same story--connection with self-assigned address, which is useless. However, this time, having nothing left to lose, I restarted the modem/router, which presumably dumped any inactive connections and issued new DHCP leases.
However, I do have a few words for the Apple GENIUSES! The Leopard network preferences page puts me in mind of a maintenance free battery. A few of the older folks will remember when you bought a car battery that had to be filled with distilled water to reconstitute the electrolyte. Then, periodically, you check the level of the liquid in the battery, and added distilled water when required. Adding water was required on occasion because some of the water would boil off under certain conditions. Then, we got the maintenance free battery, which is virtually identical to the older battery design, except that you don't have to perform the maintenance of replenishing the water. It turns out, however, that maintenance free batteries do vent on occasion, and should have water added. But, you can't add water because the battery is sealed. So, the difference between conventional and maintenance free is not that the maintenance free battery doesn't need maintenance, it is that you can't perform the maintenance without voiding the warranty.
The Leopard network preference page won't let you set the parameters that could restore a connection. If the DHCP client doesn't work automatically, you're stuck.

DHCP & self-assigned IP problem-Airport doesn't work

I'm not really a technical type, but I'm pretty quick to pick things up and several weeks of trying to deal with this issue has made me pretty knowledgeable about things related to it specifically.
Background:
I have a month-old Macbook Pro that runs Snow Leopard and is up to date on all its software stuff. On our home network we have another pretty new Macbook Pro running 10.5.9 and a fairly old Macbook also running 10.5.9.
We have a Linksys WRT54G wireless router. Our network uses a 40-bit Hex WEP password.
Problem(s):
When I try to connect to our wireless network, Network preferences tells me that it cannot connect because of a self-assigned IP address. Sure enough, the IP address DHCP comes up with is of the 64.XX.XX.XX variety. Google's revealed that this is a common problem for all recent versions of OSX, back to at least Tiger.
The "subnet mask" it comes up with is 255.255.0.0, which is different from the settings on our other (working) computers, which is 255.255.255.0. I'm not sure what this means, or whether it's significant. Renewing the DHCP lease either comes up with the same 64.XX.XX.XX type or, sometimes, it comes up with no IP settings at all. The most frustrating thing about this is that if I chose "DHCP with manual address" and type in any in our set that I've confirmed isn't in use and hit "apply", as soon as I go back to the panel it has reverted to the 64.XX.XX.XX type.
I've also tried manually entering the router/subnet mask/IP data, as well as the DNS numbers, and that leads to the Network Settings connectivity dot thing being green, but the internet still doesn't work. In those cases, diagnostics claims that everything is fine up to and including the ISP, but that it's unable to connect to the server and internet.
Of note: some people with a similar problem have talked about networks with this problem working intermittently, but mine seems to be consistently broken.
Initially I was able to avoid fixing the problem by using our neighbors' unsecured wireless network, which is sort of awful, I know, but at least it kept me from having to deal with this for a while. Today it started to do the same thing to that network. Both networks continue to work on our Macbook and other Macbook Pro, which is why I don't think that it's a router problem.
I've been able to connect to our other computers through computer-to-computer networks—going through our main shared network (and thus the wireless router) doesn't seem to work—which I think shows that the Airport card/hardware itself is intact (?). I did try connecting to the internet through the "internet sharing" option on our Macbook, but that had the exact same problems.
Another thing that may or may not be relevant, but is equally infuriating:
I've also noticed that my Macbook Pro has more trouble staying connected to a network than our Macbook—even when it was working, it disconnected/timed out extremely often, which is something our Macbook never does, even from the same location. When I try to connect to a network it spends a very long time displaying the "searching for network" animation in the menu bar icon, sometimes after the Network Preferences pane believes that it's connected, and sometimes even after I hit the button to turn Airport off. It's also started refusing to connect to any networks at all, on occasion, which is especially evident in the process of the diagnostics box thingy, because there it actually tells me it's unable to connect rather than just playing the searching animation for ages.
Here are some other things that I've tried:
setting up a new 'location'
restarting the computer
deleting the airport preferences file
restarting in safe mode
restarting open firmware
confirming that the firewall allows all incoming thingies
resetting the router
making sure the keychain password allows all applications to access it
connecting to the internet through a computer-to-computer network from another machine
Because the situation has deteriorated over time, I'd also like to know whether people think that it's two problems (the type of router then later the airport hardware(?)/software(?) itself, perhaps) or just one. Since I've tried basically everything besides switching out our router, I'm kind of inclined to blame it on that, especially because one of the more plausible explanations for this problem that I've heard is a time-out error due to Airport expecting a faster response than it's able to get from older routers; however, the fact that other networks haven't been working means that it's not likely to be just the router. If it's just one problem, which is the simpler explanation, then I guess there's something properly wrong with my computer's software, in which case I guess I'll take it to the Apple Store. :/
I'm in love with my computer otherwise, and I'll admit that I spent a good twenty minutes sobbing out of frustration over this. Any help would be immensely appreciated.

HI and Welcome to Apple Discussions...

TS1398 Has anyone had WiFi connectivity issues with their iPhone 5 after accepting the latest IOS 8.0.2?

Has anyone had WiFi connectivity issues at home with their iPhone 5 after accepting the recent IOS 8.0.2 update?

Yes, despite being it an iPhone5 (8.0.2) attempting to connect to an Airport Express.
In my case the iPhone "connects" to Airport Express 2nd generation, but no Internet packages are available; Airport Utility shows the Airport Express as not connected to the Internet; but the iMac, MBP, Motorola phone, Samsung Smart TV and HP printer connect without any trouble.
The actual issue is the DHCP :
sometimes the iPhone gets none, and
when an address is assigned it just doesn't work,
even renewing the address won't work all the times,
switching off and on the WiFi won't work all the times neither,
going on Airplane mode, then back won't work all the times.
Solutions attempted and failed:
Reseting and reconfiguring Airport Express;
Reseting iPhone;
Switching off and on the iPhone;
Setup the DHCP renewal for every 5 days;
Meditation and stark visualisation;
Other possible patch not yet attempted : setting fixed IP addresses
All suggestions received resemble Windows' "Plug & Pray"
I gave up after reading several notes around the WWW complaining about it.
Last credible suggestion : wait for 8.0.3 or 8.1, whichever fixes the issue first.

HP Slate 21 Pro: WiFi connection issues

Hi,
I recently ordered two HP Slate 21 Pro devices. Unfortunately, both of them have WiFi connection issues. After some time the properly configured WiFi connection will be dropped, which results in connectionless devices. The WiFi AP is disabled after this, and so a timed reconnect will not succeed.

That really shouldn't affect it.
I'm a little stumped because I haven't seen this issue with this device before. The only similar issue I found was this, and it's unresolved.
Have you tried doing a hard reboot of the Slate 21?

Is there a fix for the wifi connectivity issue after ios6 update?

Is there a fix for the wifi connectivity issue after ios6 update?
Cannot connect to any wifi since update to 6.0.1
How do I get update to 6.0.2?
Will that even help?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Bad corporate wifi connection issues

Hi,
I've experienced a corporate wifi connection issue.
Having the issue on two z3compacts (latest kitkat build) and also with a Z3 (also latest kitkat build).
connection details:
EAP-Method: PEAP
Phase 2-Auth: MSCHAPV2
CA-Certs: no
Identity: yes
Password: yes
Issue is the following if you roaming between APs it happens the the smartphones jumps to a next AP with better signal but it is not possible to connect to the wifi.
There are two workarounds:
1. re-enter the password for the connection again
2. turn on airplane mode and turn it off again
The state is very annoying.
We've tested various Samsung and Nexus smartphones and we couldn't experienced that issue.
Any of you experienced the same?

Hi Phy,
thanks for that hint!
Can't believe anymore that it is a network component issue...because,
We have 500 android devices integrated (LG, Samsung, Nexus) and also nearly 4300 iPhones (4s, 5c, 5s and 6 (IOS7-8))
Besides them three xperia Z3 devices for testing purpose.
We only experienced this issue with the xperia devices.
Actually we're observing this issue over a month now.
We checked also the wifi controler logs and we saw that the xperia devices quit connections and connections tries by themselves.

Still having WiFi connectivity issues. What can I do to fix this?

I have the new Macbook Air 2013, and since day one i have had WiFi connectivity issues. I know that this problem has been worked on and that a recent release of an update could help fix this problem. However; nothing for me has changed. I connect to my home internet and sooner or later my MBA disconnects and i have to reconnect it by either turning the WiFi on and off or going into network diagnostics. The time of my Air actually being connected varies from a coulpe second to a couple minutes and occasionally I may get 30 to 45 minutes before a disconnect.
If you could help it would be much appreciated.

That statement is unfounded, actually. ALL of those currently with wifi issues are able to connect via their iphone hotspot, or by means of their homebase AIRPORT base station, .....indicative of a software/ firmware issue.
Most dont consider a minor software/firmware issue an empirical defect, anymoreso than "forgetting something" is an empirical defect in a human being is.
The "speaker issue" is now uttterly proven a simple software issue, soon to be fixed, same is the case with the wifi issue.
You're forgetting that Apples 802AC wifi is "next generation" 'tomorrows' technology. That a minor bug exists, soon to be fixed, is understandable. Look on the bright side, ....the Macbook AIR is #1 seller and most beloved superbook out there for many reasons

Wifi Connectivity Issues, how to Downgrade

I am using a 13 inch macbook late 2007 model running snow leopard 10.6.4 My problem is that after waking my macbook from sleep my wifi errors and has the connection timed out or the invalid password when it is correct. My roommates are able to connect to the router perfectly fine and My airport can connect to my home network as well as the campus network. I have tried the various fixes including trashing the system config folder, adding a new location, deleting locations, adding and removing airport, adding and removing preferred network locations, repairing disk permissions. Im sick and tired of trying to find a work around to this problem. I have time machine enabled but I don't want to roll my computer back an entire year just to fix wifi connectivity issues. Is there a way to downgrade without losing my applications, and personal files. No i didn't make a back up before install, I just want a to downgrade to 10.6.3 which I never had connectivity issues, is this possible?

It is managed by apple but no direct responses are from apple, yes i have had problems in the past with arrogance and users showing no respect for "noobs". The genius bar is located 2 hours away and when I do have access im skeptical to leave my macbook with them because i NEED it for school work. But my intentions weren't to be negative but to shed light on a problem. I was being sincere and sometimes the truth is negative; there is most certainly a need because without bringing attention to problems how is anything going to get solved or changed? Also if you reread what i posted it states "Finally a forum where members AREN'T arrogant", meaning that I WASN'T referring to this forum.

Possible solution to iphone 6 wifi connect issues

Re: Why does iOS 8.0.2 not resolve the issue of WiFi connectivity with iOS 8 and the new iPhone 6?
Trying to keep this thread alive. I had luck with what I discuss there.
I want to add to that:
After restoring from an icloud backup from my 4s, I never allowed my new iphone 6 to create its own new backup. I didn't have enough space on my icloud account. I meant to upgrade the space but every time it asked I didn't have my CC around (it wanted to verify my cc info)... so I just cancelled and figured I would do it later. After deleting both the old and incomplete new backup... my wifi connectivity issues went away. (who knows why?)
This has worked for a few hours now.. Something is for sure different. Anyone with this issue try this and let us know how it works .

iphone5s wifi is **** slow since I updated it to ios 8.0.2 It isn'tmy router because my laptop and PC
are fine.my wifi is working fine even on Samsung Galaxy s3. I am able to stream movie on youtube on S3 but not on Iphone 5s. even whats up messages take long to download on iphone 5s.
I have tried the following on the devices and nothing has changed!
Turned Wifi on and off
Forget Wifi network add again
Reset Network Settings
Erase all content and restore from iTunes backup
Erase all content and restore as a new device
Disabling WiFi in location services >does nothing
Disabling location services entirely >does nothing
Changed the network type to WPA in my router to Personal or MixedWPA2/WPA -PSK. Rebooted router.
I amfrustrated beyond belief! I shouldn't even have to try all these things and I'm even more frustrated the only way I can use my devices is by pulling from my Airtel cellular hotspot and use my data!
This needs to get fixed ASAP!
It seems like there is no Solution for IOS 8.0.2 Wifi Problem. We have to wait until apple release new update that may fix it.

10.5 DHCP issues with Wireless - self assigned IPs?

We're having an issue with Mac OSX 10.5.4 clients, running the latest software updates, not getting an IP address via DHCP on our wireless network.
We're using Cisco APs, with multiple VLANs & SSIDs. They authenticate, but get automatic self-assigned IP addresses. None of our PC clients are experiencing this issue, nor older 10.4.x OSX clients. This looks like a bug, from what I was able to discover:

Is Apple aware of this, and/or working on a fix? I've seen many issues over the last year or so with Airport clients and wireless connectivity..

This is a "user to user" help forum that is designed as a self-help system, independent of Apple's Technical Support system. No one here can say what Apple knows or is doing about a specific issue (pure speculation is discouraged). We share experience and suggest possible solutions or workarounds.
One way to ensure that your issue is brought to Apple's attention is to use their feedback form for OSX - http://www.apple.com/feedback/macosx.html
Since the link you posted is from late last year, there have been many updates to Leopard. Some of the updates mention network reliability. Even though Apple has stated that the Pram chips don't control network connections, I have had some luck by Zapping The Pram - http://support.apple.com/kb/HT1379 - Remember to check your System Prefs for things like date/time settings after you Zap.
