10.4.8 network issue with some routers (Zyxel)
Since I have installed 10.4.8 there is a problem with my Zyxel Prestige 310 router, which after a short period of time "hangs up" - so nobody in the network has Internet conection ( PC's and other Macs with 10.4.7).
After restarting the router everything works fine, until I start a Mac with 10.4.8..
This happens on Intel and G5 Macs..
Today I had a long phonecall with my Provider here in Austria, who told me that a lot of people are having this problem - all with Zyxel Routers - but he doesn't know a solution.
He (and me) is waiting for a fix from apple...:-)
I also have an issue with the 10.4.8 update and a Zyxel router, although mine is not as severe as yours.
Mine has to do with WPA encryption and a timeout setting.
The thread is here:

So, maybe this helps?

Re: Anyone still having IOS 6 wifi issues?
created by mpa9366 in Using iPad - View the full discussion
Having done a lot of reading today and having found a very good online tablet magazine (will post link tomorrow) there seems to be a few tech bods onto the problem.
The magazine I was reading identified wifi problems within hours of the ios 6 release and have been analysing since then with almost daily updates - the story seems to be:
The apple authenthication transmission is normal, it should slip through event prior to a full handshake with the host network being completed - however if not authenthicated then apple will not permit the device to connect (kills the connection) this is designed to protect apple from counterfeiting. So thats problem 1 if you dont receive a token from apple.
Problem 2 is that ios 6 only supports ipv6 (the new ip protocol) whereas outside silicon valley a large proportion of routers modems etc are still ipv4 protocol.
So youre locked into ipv6 in a world where ipv4 devices are everywhere and apple have not allowed for the ability to handle both protocols. This is like GM telling you your car requires an upgrade, everything will improve etc and as part of the upgrade fits a fuel cell motor and stays silent when their upgraded vehicles are simply parked up because they cannot get fuel.
A very basic expectation would have been dual protocol handling - we know the HW supports ipv4 as all wad fine on ios5.
So its going to be hit and miss with networks - more hit than miss in techy areas like silicon valley, but more miss in places like where I am - a small town in rural Switzerland.
Only apple can fix this with a patch to enable ipv4 protocol handling.
There you go. you just need to buy a new router, I'm sure Apple has one for sale, cause it's not there fault for sure.
Wonder why people start to migrate to other devices ? -
New Airport Network - issues with some specific features
Hello,
I have just changed my wifi system for an Airport Network, with one AirPort Extreme and 2 AirPort Express. The goal was to extend the wifi network to the entire house. Everything is fine, all my computers are able to connect to the network and are able to access the internet. The AirPort Network is connected to the internet with the PPPoE procedure.
The issue is very specific here.
1. I use Outlook 2007 to handle my e-mails. Since I have shifted to the AirPort Network, Outlook is not able to connect to pop server anymore for 4 of my 5 accounts. Hotmail (pop) is functionning alright but Gmail is blocked !
2. Windows Update is also unable to connect to the appropriate server.
Maybe there is more but it's all I have noticed so far. I have not changed a single parameter by myself on my computers and both are affected the same way.
I first thought it was a firewall issue but disabling my software firewall (Bullguard) did not change anything. Vista Firewall is not active. Maybe is it the internal firewall of the AirPort Extreme ? But that would not explain why Outlook can send messages (smtp works fine).
Any idea or similar experience ? Thank you in advance.
Best regards,
AdGMaybe my problem is just bad luck ! I might have shifted to my new network
the wrong day. One day earlier, I would not have seen any difficulty... if this is it.
Quakes slow cyber connections
By Zhu Shenshen | 2009-8-18 | NEWSPAPER EDITION
SHANGHAI'S international Internet connections slowed significantly yesterday after earthquakes rocked Taiwan and southern Japan. It was unclear last night how long repairs might take. Millions of Chinese Netizens were unable to connect to overseas Websites or use popular online chat tools yesterday afternoon.
About 15 million MSN instant message users in Shanghai and other parts of China were affected as the main servers are in the United States. Connections to most overseas Websites including those run by Yahoo and the New York Times were also clogged.
The chain of events that led to the service disruption had its origin in Typhoon Morakot, which struck Taiwan on August 7 and led to a later breakdown in an undersea telecommunications cable system.
Local Internet traffic was not influenced because transmissions were routed to a backup channel. But that cable failed yesterday near Busan, South Korea, apparently the victim of the earthquakes, according to China Unicom.
The failure affected Asian communications to the US and Europe.
The epicenter of the first quake, which struck at 8:05am yesterday, was about 188 kilometers southeast of Hualien on Taiwan's east coast at a depth of 11km, the island's weather bureau said. The US Geological Survey put the magnitude at 6.7.
The second quake, which was centered close to the first at a depth of 20km and struck at 6:10pm, measured 6.1, the Taiwan weather bureau said. It was also felt in Japan's Ishigaki Island.
"We've sent a team to repair the broken cable, but we can't give a detailed timetable for when it will be completed," said Song Guixiang, a public relations official for China Telecom.
The schedule will depend heavily on weather conditions, Song said.
Repairs are handled by a team comprising the carriers that use the cable.
In most cases it takes one to two months to fully repair damaged undersea cables. In the meantime, telecom operators will try to reroute traffic to operating cables and satellite systems.
Domestic Internet connections and international call services were normal yesterday, the carriers said. -
Hi,
I have an issue with some PDF documents & some MS Office documents, notably MS Word when received in eMail as attachments not displaying properly on iPhones, iPad 2s & new iPads?
PDF docs - areas of the doc only show as grey splotches regardles of viewer
MS Word Docs -
inserted graphics don't display at all,
tables & lists especially with borders are broken &
tables & lists missing the borders &
tables & lists missing the 1st 1-2 lines of the lists/tables.
This is replicated on iPhone 4s, iPhone 4Ss, iPad 2s, iPad new (x2)
It certainly happens in iOS 5.1.1 & iOS 5.1
We believe it all worked aok in iOS 5.0.1(?) & prior
There is no problems reading/seeing these PDF & Word docs on anything other than iDevices.
This is rather critical for us & if not quickly fixed/rectified will prevent us from further purchases of these devices
Rolling back to iOS 5.0.1 or prior I believe isn't possible because of the BaseBand update(?) & isn't much of an option because of the quite noticeable Battery/Charging/WiFi improvements in 5.1 & 5.1.1Hi,
I logged a call with AppleCare & have since had explained why this occurs (some time ago)
I'll try to explain what was indicated to me.
iOS has a limited Font Set & this affects what PDFs can display. You need to use iOS supported fonts in your PDFs to see/read them properly
These supported fonts are indicated here => http://support.apple.com/kb/HT4980
Regards MS office docs, iOS doesn't have much of an API to work with MS Office documents at all so is stuck with 3rd Party Apps to try to do it.
Unfortunately Mail in/on iOS uses the API to attempt to open/use MS Office attachments unless you tell it to use an App to open the attachment.
I have had success opening & reading MS office docs now with CloudOn, but find it slow & very awkward to use.
Not too sure if this helps others, but at least it explains why this is occurring -

Unusual network issues.. some programs work fine... others not.
I'm staying at a small hotel and was pleased to discover they had wireless Internet access so I won't have to go to the local Internet cafe to do my work. Or so I thought. I connected easily to their network and immediately went to Speedtest.net to test out the connection. 150ms ping time, 263kbps down, 213kbps up. Believe me, that's the best you're gonna get here in Tobago. Fast enough for me to do my work (which requires multiple Remote Desktop Connection sessions). Here's were it gets weird. First thing I noticed is that Adium quickly connects to MSN and AIM but cannot connect to Yahoo. Countless reboots and reopening of Adium do nothing. I find Mail sluggish at times. Frequently my mailboxes show the connection error symbol however hitting the "Get Mail" button will rectify this. Browsing works fine. Relatively speedy and no issues with any specific kinds of content. Skype seems to be working fine. Remote Desktop Connection can't connect to anything.
I'm more an Applications Programmer type so I'm not too knowledgeable about the intricacies of network protocols. Anyone have any insight what would cause behavior like this? I seriously doubt they are blocking certain protocols. They seem the types that have just enough knowledge to plug in their wireless router and give it password.
Well.. I'm off to the Internet cafe. If you have any suggestions... feel free to pass them along. I'd rather do my work from the hotel.Only thing I can think of tht you might have control over, might be to change the MTU, some Routers don't work right with the default 1500.
You can test it with a temporary change by using Terminal, with...
sudo ifconfig en1 mtu 1460
or...
sudo ifconfig en1 mtu 1400 -
Network issues with Apple products?
I've got a weird issue with my Apple products connecting to certain networks. Two different instances:
1) My parents house, my iPhone, iPad, and MacBook Pro all have issues in contacting certain sites and apps. Things from google or apple servers wont work. Some things do, if I VPN to an outside network, everything works perfectly fine. I haven't been able to figure out what the root of the issue is. I've switched routers and contacted the network provider but they said it wasn't there fault. This has been going on for a bit. All non-Apple products seem to be fine.
2) My office, I know even less details about the network here, but I'm having a similar issue where my Apple devices get connectivity for a bit then stop and then come back later. If I VPN again, everything works perfectly fine. All non-Apple products work fine.
Anyone have any idea as to what this could be from?I am having the same problem since upgrading to Snow Leopard. Really need an update from Apple or a solution. Been reading a lot of posts on several discussion boards but nobody has come up with a solution yet. Apple really needs to send us a fix for this. I understand it is also hapenning in Lion.

Just swapped out routers (Belkin to Airport Extreme). Lost connectivity to printer, and have been able to reconnect with USB and going through USB port on Airport Extreme. Problem is I can't get the printer networked as Bonjour Multifunction...get the following: "An error occurred while trying to add the selected device. Unable to communicate with the printer at this time". I have updated the network password on the printer and it has an IP address with good signal. Printed configuration page says everything is OK. I have unplugged, restarted, reinstalled EVERYTHING, to no avail. BTW, when I try to check for updates on the printer itself, I get the a Server Connection Error:
Any advice would be appreciated.Hello @wfriedmanct,
Welcome to the HP forums.
I understand that you have been having some networking issues since you switched to the Airport Extreme.
I would like to help.
The router may need to have some adjustments made.
~ Multi-casting needs to be on or enabled (Allows Bonjour Connectivity)
~ Wireless Ports, these can also be blocked in security software:
Incoming (UDP) ports : 137, 138, 161, 427
Outgoing (TCP) ports : 137, 139, 427, 9100, 9220, 9500
~ Our printers only support 2.4 GHz not 5GHz
~ Recommended that the network name and password DO NOT contain and spaces/punctuation or special characters
~ Dual broadcasting enabled (for wireless b/g and n networks)
If you are getting a server connection error then the printer either does not have internet access or is getting lost.
I would try a manual DNS.
The following reply by happytohelp01, has instructions for setting the manual DNS.
It is for a 7510, but the steps will be very similar. If you get stuck, please let me know.

Very Strange Network Issue With Two Guests on 2012 R2 Hyper-V Failover Cluster
Hi all. We're having a odd issue with two guests on our 2012 R2 failover cluster.
In a nutshell, if we shutdown a particular server (I'll call it Server A) another totally different server (Server B) on the same node loses it's network connectivity to the domain. If we start server A back up, network connectivity returns on server B.
At first I thought server A might be running a service that was somehow linked to server B, so I decided to disable server A's NIC. Interestingly, that had no affect on server B's connectivity.
The next step I tried was pausing server A and again, no adverse affect on server B's connectivity.
Next step was to live migrate server A to another node. This action did
cause server B to lose its network connection.
One other clue is that if I ping server B from either of the Hyper-V hosts in the cluster, I never lose network connection to server B.
So I would suspect this is some network issue on the cluster, but I'm kind of at a loss where to go from here.
Has anyone seen this behavior before or does anyone have any troubleshooting suggestions I can try?
Thanks!
George MooreHi Sir,
I'v never seen this before .
>>Next step was to live migrate server A to another node. This action did
cause server B to lose its network connection.
They are connecting to same virtual switch ?
First please run cluster validation to check if there is any error .
If it is ok , please try the following items for troubleshooting :
1. shutdown serverA serverB
2. then add another virtual NIC for serverB
3. start server B check if the issue happens to both "old" and "new" virtual NIC .
In addition , you can live migrate both A and B to another node , then try to live migrate A to the original node .
If the issue persists , I would suggest you to remove that virtual switch on both nodes then re-create them .
Best Regards,
Elton Ji

Network issue with initial connections on Hyper-V
This is the opposite of all the other networking issues I have seen with Hyper-V- anyone run into this?
I am running Hyper-V on a Server Core installation, and have had the same issue when I used Server 2012R2 as when I used Server 2008R2 on the same server as a virtual host. The server is an HP ProLiant DL360 Gen8 with 2x 8-core processors, 32 GB RAM. The
VM is sized and configured to stay within 1 NUMA node. It uses a single port of the 4-port HP/Broadcom 331 NIC, with all the TCP LSO settings disable at the switch, host, and guest, same with the power management settings. We have ProxyARP on the network,
so I have set the ArpRetryCount key to 0.
I have seen it happening with and without SR-IOV enabled. The guest OS is an RDS server, so for the sake of our CAL's it has to stay at Server 2008R2. I have set up a HOSTS file to mitigate this problem, as it seems to be a DNS issue- Here's what happens:
The first time I visit a resource, the server will timeout. An example not in our HOSTS file does this consistently: If I go to https://mail.mydomain.com/OutlookWebAccess, it spins for a couple of minutes before timing out. I hit refresh and the page loads
immediately. This server is colocated in-house, as is the mailserver. I'd say it is a DNS issue at some level, but I'd like to know what level it is- Is it just timing out trying to cache the DNS request, or is there a performance issue with a DNS server on
the network? (All of our DNS is AD-integrated running on DC's).
Here is where I'm seeing this:
Internet Explorer- described above
Salient Interactive Miner- at the login screen, it searches for a database and times out. If I go to the setup and enter the IP address, it still times out. It will not find the database server until I quit and restart the program. If this is the same issue,
it would obviously not be a DNS problem.
I DON'T see it in GP9 connecting to a datasource
Prior to setting up the HOSTS file, I saw this in Windows Explorer connecting to network shares on the same LAN segment.
This appears to only happen to the Hyper-V guest OS. As a best practice, whenever Windows Update runs, I update the Integration Components.
I have the bindings properly ordered on the guest VM, with the network adapter the goes to the physical NIC first, and IPv4 ordered before IPv6.
All updates are isntalled, and the firmware is at it's latest revision.
Any ideas?Hi Daniel,
" This appears to only happen to the Hyper-V guest OS. "
Do you mean that any other hosts can access the network resource normally except these VMs ?
If yes , my suggestion is to disable the VMQ on the physical NIC for the VMs , then try test again .

Networking issue with Leopard 10.5.2, Arris Touchphone, Netgear WRG614 v4
I recently upgraded to Leopard 10.5.2 and now having long hang times of 15 seconds (if I connect at all) to internet. It's not a signal issue, AND I have a PC that flies on same wireless network.
The same time I loaded new OS, Comcast came in a changed out my Motorola SURFboard SB5120 modem for Arris Touchtone Telephony modem. I am still using the Netgear WRG614v4 with the most updated firmware(V5.0_07)
Of course, I wasn't sure if not being able to connect to internet was a Leopard issue or a networking issue. After many hours of troubleshooting...
1. MANY hard resets through cable company AND buttons on both modem and cable
2. Applied all the newest Updates to 10.5.2 which fixed the issue for about 2 hours, then back to crawling
3. Changed the channel on the Netgear from 11 to 9
4. Went to Starbucks AND Panera Bread and had fast connectivity even from the parking lot!
Although I expect some issues to pop up from the new OS, I now believe the connectivity issue is with either the new modem or router. Comcast insists that their firmware is up-to-date and is automatic.
Should I get a new router? HELPI've been on the road and everything is working fine, but now I'm back home and the same issues.
BUT for some reason, after a day, something switched up and now the mac is on-line and the PC is not. They are definately fighting each other. Even the wireless printer is wacked. Sometimes when I try to print from the mac, it can't connect to the printer. I then either restart the mac or restart the printer, and it goes through.
The other issue now is that all the lights on the Arris modem are blinking. Comcast is saying something is wrong. They are coming out today. Wonder if I just got a bad modem.... -
Strange Networking Issue with OES
Since moving our entire infrastructure from Netware to OES, I've been trying to figure out a very strange issue. We are a K-12 school system with a data center at the central offices and a single server at each school. The data center has the servers that run all the centralized stuff, including the Master replicas for [root], the DA's for SLP, etc. We noticed that sometimes a school's server will drop out of the SLP tables. When that happens, we also cannot SSH to the school's server from the central servers. We can SSH to it from any other machine on the same subnet as the central servers. The central servers can ping it, but no UDP/TCP traffic can pass between them (no web traffic, etc). We finally realized it only happens when the ISP that serves that school has a brief blip or outage of some sort. The only way we have found to get the servers talking again is to reboot the central servers.
We have tried:
Restarting almost all services on central servers
Stopping and restarting networking
Switching to runlevel 1 and then back
Stopping firewall and/or shutting it off completely
Checking hosts.deny files
Disabling virus scanner (McAfee Enterprise)
Changing vmware network drivers from E1000 (known issue with vSphere 5.1) to VMXNET3
All servers run on HP Proliant servers (blades at central office, towers at schools) running vSphere 5.1. Links between the central office and schools are all 100Mbps fiber via two different ISP (depending on the school's location). A restart of the central office server fixes it every time. I am out of ideas now and at a loss as to why this happens when a WAN link goes down. We thought it was just isolated to one ISP, but it was just that that particular ISP is not quite as reliable as the other. We had an extended power outage at a school served by another ISP over the weekend and saw the same issue with that server after power was restored.
Any ideas or suggestions at where else we should be looking? We also run ZCM 11 at each school and the central office. When this happens, those servers never lose connectivity with each other and with the OES servers on each end. The ZCM servers run on the same vSphere host as the OES servers.On 04/08/2014 12:26 PM, jmlester wrote:

To be clear, while i think this correlation is possible, I do not see any
possibility of causality in here unless your SSH client is somehow using
SLP to resolve the SSH server, which seems very unlikely. I'm not sure if
you're trying to state that SLP is the cause of the SSH stuff, but I do
not think you are.

Hmmm........... so routing works, and the server is even responding to
requests made to it (presumably, or something else is), but SSH is not
responding, or something is preventing it from responding.

I'd get a LAN trace from both sides at the same time. At the very least,
run tcpdump as shown below on both the central office machine as well as
the remote machine to see how the packets differ when trying different
things. If you do a test and do not see output on both sides, do it again
writing it to a file and post somewhere for us to review. Note: since
it's an SSH problem I would either NOT SSH into the system, or I'd be sure
to limit the tcpdump capture/output to something specific to the
connection being tested. Tracing something over which you are sending the
tracing data is never fun since every packet picked up causes another
packet to be generated, to be picked up, to be generated.... ad infinitum.
To see tcpdump output with limited details on the screen:
Code:
sudo /usr/sbin/tcpdump -n -s 0 -i any -vv
To write tcpdump output to a file:
Code:
sudo /usr/sbin/tcpdump -n -s 0 -i any -w /tmp/problem-20140408.cap
While filtering when capturing is typically not desired, you can do it by
adding something like 'host 10.1.2.3' to the list of tcpdump parameters at
the end of either of those two commands. The reason filtering during
capturing is not desired is that you may miss something.... the SLP
traffic, DNS, ARP, ICMP error showing the exact problem, etc.
Good luck.
