Some website cannot reach
871W with 2VLANs, VLAN 1 is native VLAN for cable connect. VLAN2 is for wireless and the wireless clients can associated to this VLAN2 and can reach Internet but some website cannot reach such as www.info.gove.hk and Windows Live Messenger also cannot login too. If same wireless client PC using cable connected to this 871W directly then all website can reach and Windows Live Messenger can login too. Any idea? Please help.
This type issue often has to due with fragmentation issues. Try adding "ip tcp adjust-mss 1452" to the BVI interface you have the wireless interface mapped to if you have the wireless in a bridged config or the dot11 interface if in a routed config.

I cannot view some videos and participate in some websites since Adobe upgraded all to Flash 11.7. I have an older Mac G5 PowerPC (no Intel chip) running OS 10.5.8. I keep getting splash screens saying I have to update to Flash 11.7 but 11.7 is made for those Macs with an Intel chip. I am running the newest Flash for my system. It seems all concerned should have made Flash retro-compatible for those of us with older Macs. Is there a work around to this Flash requirement short of buying a new Mac with the Intel chip?
I'll bet you'll have better luck if you post your question in the Power Mac discussions here: https://discussions.apple.com/community/desktop_computers/power_mac
Either that, or one of the forums at Adobe.
Good luck.

Problems to reach some websites
Hi,
I'm asking for your help about a problem I have been struggling with for about a month.
Background information:
- 3 client computers (2 on Windows Seven, 1 on XP),
- 1 Windows 2012 server (AD service active)
- ASA 5505 router for the WAN connection (Orange as provider)
- PPPoe Authentication used with DSL provider box set in modem mode
Problem:
All clients except ONE (on Windows seven) have problems to reach some websites. Some work well, but for others, it keeps waiting for the connection until a timeout error message.
The clients affected are also unable to update the virus database.
Using an anonymizer service as anype.com, I can finally reach the websites that timed out...
The affected clients use the same DHCP as the one that works.
Sending a ping from the affected clients to the unusable websites gives the good ip adress.
Using an external laptop which works well on another network on this network gives the same symptoms.
I can see no configuration differences between clients and even reinstalled one of them from scratch without more success.
Did someone experienced this kind of problem? I'm running out of ideas!!!
Thanks in davance for your helpPPPoE will add 8 bytes and IPsec VPN will add as much as 80 bytes to the original packet. So the packet will be larger than MTU down the path between client and server. but those packets maybe set df-bit, so ICMP type 3 code 4 (packet need fragment but df-bit set)will send back to the originator, but sometimes it can not reach the originator due to FW block or ACL or packet drop. so the connection will be timeout.
Workaround: configure 'ip tcp adjust-mss 1360' on WAN router (here FW), make sure all the WEB access can work, then you can increase 1360 to bigger number until you reach a balance.
Some WEB server did not honor MSS advertised by client side during TCP 3-way handshaking, it will result in packet from server side will need to be fragmented down the path to client, if DF-bit set, it also cause session timeout. -
I have recently updated to ios6. But safari browser is very slow ,even twitter, Facebook also facing the same problem also cannot accsess to some websites too.
Try these basic troubleshooting steps.
Quit all apps completely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Or .... Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
For Safari ..... Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button. -

Intel version's Safari cannot display some website's photos (but PPC cannt)
The Safari (Intel) is not able to display graphics/photos in some websites, (like http://www.fotop.net).
but if running the safari in rosetta mode, it will able to display so.
Can any one help to know want happened?This MacOSX Hints page shows how to enable the debug menu, which also allows you to change the user agent.
Since the site works fine on Safari 2.0.3 ( 417.9.2) for me, I'd say that the website simply need to update their User Agent identification info to account for the latest versions. But hey - just tell both partys.
Hopefully someone else here with an Intel Mac can confirm if the site works for them. -
Complex DNS? Cannot reach XServe from inside network
I'm trying to make DNS work on a XServe with Leopard Server installed.
I had to migrate (mostly manually) DNS from the old server.
The server runs DNS for about 50 websites, most of them on the server itself, some on other local machines. All these are configured with their external ip addresses.
From inside the building i cannot reach the server unless i make a subnet so the xserve acts as a router to. Then I can also use Server Admin e.g., which I cannot use without that subnet.
From witin the server DNS seems to work while just browsing the domains with Safari.
sudo changeip -checkhostname
Primary address = 10.0.2.15
Current HostName = dns.myserver.com
The DNS hostname is not available, please repair DNS and re-run this tool.
So i guess i made a mess..
host on xserve ip address (also from within xserve)
odin:~ admin$ host 10.0.2.15
Host 15.2.0.10.in-addr.arpa not found: 3(NXDOMAIN
host command on external ip address gave me one of the domains, but not dns.myserver.com.
$ host 192.xxx.xxx.xxx (of course i used the full external ip address)
192.xxx.xxx.xxx.in-addr.arpa domain name pointer dns.myserver.com.
Can anybody help?

Unable to load some websites after an update to IOS6
I am unable to load some websites in both Safari and Google Chrome. This did not bother me until I found at that I cannot access some websites I can access before and frequent. I am unsure if this was caused by the update to ios6, but this incident only happened after the update. I am unsure as well if this is related to the problem of me unable to connect to itunes and app store after the update. I've fixed those by changing my DNS to 8.8.8.8 and changing the time trick. I've also noticed that twitter and some apps crashed a lot. I have no problem connecting to the wifi though. Thank you in advance.
Some additional details I have also noticed. Some images will not show or appears as a blue and white question mark in some websites. Even here in apple website.

Why do some videos from some website stop working after seconds or minutes on a new iPad
I subscribe to some website posting videos. The videos will start as it should and then stop after, sometimes seconds, and sometimes minutes after the beginning.
The iPad is less than 3 weeks old. it is already the second. The first was a 16 GB this one is a 32 GB. no difference. This issue does not happen with only one website but other posted videos from other websites.This and other answers helped me to understand better why I cannot view these videos and search for answers. I found that the videos posted by this website end in .cfm, and doing research cfm is Adobe and is not compatible with apple software ? why this is not resolved is surprising to me - Several other people experience the same issue as I (dating 2007-to 2013) I am not computer literate but I know how to find information on the web and know +or - how to use the programs. There seems to be nothing that will convert these videos into a format that the iPad could process and allow. should I buy quicktime for my windows device and transfer/sync it to the ipad (?)(3 weeks old I paid $900) will this work. I have tried to upgrade the firmware to my router but no luck there either; even following all the steps religiously. the unzip is not working? I get a file the upgrade button rejects.
if it is this cfm format that is doing that, then there is no reason to spend x$ into a new router : the issue will remain the same- is this statement correct ?
your help is greatly appreciated. -
Despite my Javascript for Firefox 23 being "enabled" ( I checked re the "about:config" steps), some websites are still asking me to enable my Javascript to view content. Safari works without any problem. OS/X 10.8.4
These files are hidden to me because my OS/X is 10.8.4 and I cannot make them appear. This is way, way more trouble than it's worth. Thanks for your help. Firefox has lost me.

Flash Player doesn't work on Mozilla Firefox and IE, on some websites.
I followed the thread posted by brawlmanjr on this same topic but nothing worked for me.
Basically, some videos work prolperly on some websites, but on others, there is a black space where the video is embedded, and there is no link to the video.
System: Windows XP
Browser: Mozilla 3.6.8
Flash Player the most recent, just updated.
What do you think I can do?I have the same problem than you, flash player works fine with some site like facebook, you tube etc and for some other sites like CFL.CA the videos shows only a black or white screen. It's doing the same with IE or FF. If I click on the right button, I get the menu of flash player, but cannot do anything.
I tried the option of flash....no change
I tried uninstalling flash and reinstalling...no change
I tried uninstalling Java and reinstalling...no change
I checked my antivirus, but the doesn't seem to be any option blocking the videos
I am out of ideas, please help me and Heraldo to solve this problem!
I am using Windows XP 5.1.2600
