DNS/Webpage connectivity issues?

Good evening.
I'm having a problem where web pages will sometimes not load. The reported errors are along the lines of 'DNS lookup fail', 'Connection aborted' and 'connection rejected'. Direct connections using an IP address seem to be unaffected.
I've left this for a few days just incase the problem sorted itself out, but no joy. I know it's not possible to reset the DNS servers on the HH3, although I have cycled both it and the Openreach modem to no avail.
Any ideas or suggestions would be greatfully accepted.

I have already tried 8.8.8.8 and 8.8.4.4 to no avail; still intermittant problem (sorry, should have mentioned that above).
So you're getting "'DNS lookup fail', 'Connection aborted' and 'connection rejected'" when using Google DNS settings on your PC? Sounds like you didn't do it correctly.

TS1317 Internet Connectivity Issue - specifically with the DNS settings

Hi there,
I'm wondering if someone can help me resolve an internet connectivity issue on my MacBook Pro.
It appears to be a problem specifically with the DNS settings. I am connected to the internet but can only reach a website by typing in the IP address, not the domain name. The error messahe says: "Unable to resolve server's DNS address."
Regardless of whether I use Wifi, 3G modem or cable, i get the same error.
Operating System is Mac OSX Version 10.6.7
Please help!
Thanks

It sounds like your MacBook Pro has either incorrect or missing DNS IP address information in it network profile. Let's start with your wireless connection. You would find these in System Preferences > Network > Wi-Fi > Advanced > DNS tab
If your main Internet router is performing as the DHCP server, it would provide the DNS IP addresses (typically from your ISP) on this tab. You may have two or more addresses listed. If they are grayed, that means that the addresses are coming from the DHCP server.
In the following example screen shot, I am using DNS servers provided by OpenDNS. Notice that they are grayed as they are being provided by my main Internet router. Again, these should be either ones provided by your ISP or ones you purposely set up, like my OpenDNS ones.

Possible Resolution to MiFi 2200 connection issues when using WiFi

I was having issues connecting to the Internet with my Windows 7 laptop using the MiFi 2200 as a WiFi device.
My WiFi adfapter was retaining the last IP Address it had obtained ... in my case my home network.
Go to a command prompt and do an ipconfig -release followed by ipconfig-renew.
It pulls an address from the MiFi from the DHCP range and works perfectly.
Hope this works for everyone!

Maybe also check specific for the 2 different tcpip protoclas loaded.. here is the solution that resolved my connection issue:
Updated Vista Home sp1 to sp2 ( 450+MB download )
Updated Atheros AR5007 drivers to 7.6 , 2008 release... there might be a newer release but I dont want to jack with it now that I'm working.
Check in network connections for wireless connection.
I had 2 TCPIP protocols loaded. v6 and v4 .. v4 had IP and DNS hard set. changed both over to auto assign
WALLA Mifi is now working wirelessly.

N8 Connectivity issues post Anna

I was wondering if anyone was having connectivity issues with your N8 after Anna has been installed. Ive dont the simple things with the settings in the search options. I seem to still have issues getting a connection unless there is a 100% full signal. Anything less, the phone just hangs. Sometimes for 60-80 seconds before a webpage is loaded. Is this a bug within Anna?
Thanks in advance for any help. And Happy Holidays to everyone.

Have not tried with Direct Ethernet connection, but after restarting my iMac a couple times it strangely worked. Updating software now, well still downloading @ this point. Thought it was possibly the security type I was using, but I ended up back to WPA2 personal that I had originally started with. It was not even seeing my WiFi before, so I never even had a chance to enter a password. Also using an older AirPort Extreme. May be time for some updated equipment, but at the same time it has made it this far.

Constant Safari Connection Issues

I am having a lot of connection issues. It seems from reading here that others are having some of the same issues. I am running Leopard, just upgraded a few weeks ago. It didn't seem that the problems started right after the upgrade. I then added a back up drive for time machine. I have parallels installed as well.
The connection issues are not specific to Safari, although they do occur with Safari more than anything else. The errors I receive are "Not connected to the internet" or "server not found". This also occurs in Firefox and iTunes. I have checked my internet connection over and over and everything is fine. I can access all these same things with another computer.
In my diagnosis steps I have disconnected the router 'DLink DIR-655 and connected directly to my cable modem. Everything seemed to work fine using that method. However, I cannot keep it that way for obvious reasons. I have adjusted all the settings in my router, but nothing has helped.
I am currently in my XP shell withing Parallels using IE7 to write this. Interestingly I am having no connection issues within the Parallels shell.
Does anyone have any suggestions. At this point I am not sure what else to try.

newslacker -
I have solved my problem. The problem started occuring after my upgrade to 10.5. The OS seems to be having trouble with the DNS cache. In network settings my routers IP address was set as the DNS. I added an additional DNS in advanced settings. I used my ISP's DNS to do this. Since I did it everything works great and the internet is back up to speed as well.
This is a Leopard issue that I fould in another thread. One thing led to another and it worked. I suggest you try the same.

HotSync connection issue with Palm Treo 800w Sprint work around Solved !!!

I just switched from my Treo Palm Treo 755p to the The Palm Treo 800w. For the life of me I couldn't figure out why though everything was connected via USB. The Microsoft ActiveSync would work once or twice then nothing . Though I knew it was connected the charge wouldn't work either.
Here is my work around and it never fails.
If you see the Red light or Green light on your phone while connected Via the USB that means you are connected you can sync and charge.
If you don't see the red/green light on or see the phone in My computer > Mobile devices.
Plug your phone in via the USB. While it's plugged in take the battery out . Then put the battery back in. You know you are good when you see the red light or green light turn on. Red light means charging Green light means its fully charged.
I have connected every time using the take out the battery method and my Treo 800w charges / Microsoft syncs the works!!
Hope this helps I tried everything before I figured this out.

High Speed DSL connectivity issues.

Hi. I have connectivity issues with the High Speed DSL internet connection. I have had internet service with you guys for almost a year now, and since day one, I have had connectivity issues. In the past, the connection would drop once every few days, and about once every two weeks I would need to restart the modem in order to get my connection back.
I have restarted my router countless times, and even done a factory reset on the router a number of times as well.
The past two days, my internet connection has been worse than ever, with the connection being dropped about once every five minutes. And, while the connection was up, my browsing, video, and email loading times were very slow.
The internet light on the modem is constantly flashing, even when I am connected.
The gateway status info page refreshes 4-5 times a minute.
I dont know if any of the following info will help. I would like to continue with Verizon as my ISP, but if the connection issues continue, I will have to change services.
I have the Actiontec GT708WNV modem.
The gateway status info is:
Gateway ParameterStatus
Firmware Version:
GT784WN-VZ-1.1.6
Model Number:
GT784WNV
Serial Number:
{edited for privacy}
WAN MAC Address:
Downstream Rate:
13759Kbps
Upstream Rate:
1027Kbps
PPP User Name:
N/A
ISP Protocol
1483 via DHCP
Encapsulation:
LLC
Gateway IP Address:
DNS Address #1:
DNS Address #2:

Step one: Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that the final hop (bottom-most line of the trace) might contain a hop with your IP address in it. Remove that line. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.
Step two: Can you provide the Transceiver Statistics from your modem?
As to where that is, it seems to be at
STATUS > WAN STATUS.

Firmware 7.4.1 connectivity issue.

Firmware 7.4.1 connectivity issue.
I am not sure what is causing this
In the upper right menu bar of the Finder there is the icon showing the strength of the Airport wireless signal and just to the right of it is information on how long my Airport Extreme Base Station has been active (2d 11:38:41).
I noticed since I applied the most recent firmware update to the Extreme the information displaying the length that my base station has been active will randomly disappear from my screen for a second.
When I am syncing with Apple TV this becomes more constant and this information disappears from the screen about every three seconds.
While this is happening the bars showing my wireless signal remain on the screen. (I have a good signal with all the bars showing).
This is occurring on My Imac.
I get the exact same symptom on my Macbook Pro with Extreme Base Station information temporarily disappearing from the screen. I don’t sync to Apple TV with this computer so the part about Apple TV does not apply.
Does anybody know what is causing this? Also, when that information on how long my Airport Extreme Base Station has been active (2d 11:38:41) disappears from the screen am I temporarily losing network connectivity?

I too experienced grief after installing Apple's "AirPort Base Station Firmware Update 7.4.1".
My home network consists of the Apple Airport Extreme Base Station (AEBS), a DELL desktop PC (running Windows/XP), my Apple laptop (MacBookPro 15"), and my iPodTouch. The DELL PC is connected via a Ethernet cable into the AEBS. The laptop and iPod connect via wireless with the AEBS.
The DELL PC and Apple laptop were up and running. I installed the firmware update from the DELL PC. It was successful. I worked on both the PC and laptop without any problems. I shutdown both.
The troubles began the next day when I re-booted the PC and laptop. Surprisingly, the PC connected into the network. However, the laptop did not. Repeated "soft" resets of the AEBS failed to resolve the problem. The PC (Airport Utility) software could still talk to the AEBS and reliably displayed it. However, the Apple laptop (Airport Utility) software could not talk to the AEBS (wirelessly). The laptop's Airport (wireless) card appeared to connect into the wireless network but no networking functions worked. The Airport Utility software on the Apple laptop would try but fail to find any AEBS. Sporadically (very infrequently) this software would find it and display its icon but within seconds the it would vanish again.
Another curious symptom was that I noticed the hardcoded IP address for my laptop somehow got changed to a non-sense IP address (I hardcode it and don't rely on DHCP). Another curious symptom was that I noticed that the hardcoded DNS server's IP address was GONE.
After 2+ hours trying to get the new firmware's AEBS to work, I gave up and reverted back to the prior firmware (thank goodness the PC was still talking to the AEBS). After reverting to this earlier firmware, EVERYTHING immediately started working again as far as networking functions.
Does Apple really test this "crap" before they release it?

Internet connectivity issues on Mac

I was wondering if there was any solution to an internet connectivity issue I'm having on a mac. It seemed to start when I purchased a new modem: an iPrimus AudioCodes MP252 wireless router. Basically the internet connection will either drop out or become stagnant/very slow. There have been no connection/speed issues on any Windows PC or laptop, but often when you try to use the internet on the mac it precipitates a network dropout, thus affecting the connection on Windows computers as well.
I'm trying to see if there's anything else that can be done besides taking it in to be serviced. ISP support hasn't been able to fix the issue, so perhaps it is some sort of compatibility issue between that particular modem and Apple Macs. Obviously the last resort is buying a new modem.
Modem: AudioCodes MP252 Series wireless router
Mac: Mac OS X Version 10.6.8

Hi, some Modems/Routers only like Windows PCs, also see if QoS is running on it giving most resources to PCs.

If that doesn't work try changing channels on your Router.

Connectivity issues between Cisco 2901 and Cisco SG300-52

Hello,
I am having some serious connectivity issues between the hosts in my LAN.
My LAN is based on a Cisco 2901 router and a Cisco SG300-52 port switch.
The issue that has been happening is that connections between hosts on the LAN (remote desktop, extended ping, etc) is very unstable, at some point I can see a 35% lost packets on an extended ping. This happens at any time of the day and from any host.
All hosts are on the same Vlan(default Vlan) and on the same subnet. Some hosts have fixed IP addresses (servers and network equipment) and others obtain their IP address trough a DHCP reservation established on the router (reserved with the MAC address of every host).
I can provide further details if needed, because this issue is very serious and I would really appreciate any insight or support.
Many thanks in advanced.
Sair Amer
EDIT: After doing every test we could think of, we finally found the reason behind this problem.
It turns out that the switch has problems handling communications between clients at different speeds, because most of the hosts connected were working at 100 Mbps but the servers were working at 1000 Mbps (and the communication between host and servers wasn't stable).
After manually setting the speed on all ports to 100 Mbps the problems have stopped.
Many thanks for you help on this issue.

BT Infinity HTTPS connection issues- anyone else?

Hi all.
Any advice would be greatly appreciated.
I have been having considerable problems with HTTPS sites over the past few months - timing out, unable to make payments online with ClickSafe - Lloyds Bank, Natwest, NEXT, National Lottery. Some HTTPS sites load eventually but usually very very slowly or time out.
This issue is across all my devices - Macbook Pro, iPad Air, Samsung Tablet, Windows 8 Laptop, x3 iPhone 5.
If I switch WiFi off on my iPhone I can make payments over the mobile phone network fine but as soon as I switch WiFi on the problems occur again. I took my Laptop to a friends house and used their TalkTalk Broadband and no issues, all worked fine.
I have had 2 HH4 and now a HH5 and the problem still occurs.
I have Changed numerous settings, undertaken numerous reboots and complete resets to no avail.
I have enabled firewalls and disabled firewalls, changed MTU and numerous other possible fixes, but again none have worked.
I have paid for BT Tech Expert support who have been very helpful and always called back when they have said they would but they do not know what the problem is and are still working on it. Next call on Monday night.
I found this very long thread starting in 2011 and ending in February 2013, where BT customers were experiencing the exact same problems in the South West of England and it turned out to be a network issue that was resolved but it does not explain how it was resolved!

I am in Newcastle upon Tyne and would be grateful if anyone could let me know if they are having the similar problems?
Thanks for your help.

You can use 8.8.8.8 as they suggest, as that is Google public DNS.
If that fixes the problem on the laptop, it would point to a problem with BTs DNS servers.

HP PhotoSmart 7510 suddenly has severe connectivity issues

I have a HP PhotoSmart 7510 printer since about 2 months. Initial setup worked like a charm and the printer has been working pretty much perfectly for the last 2 months. Wireless printing, scanning and internet access on the printer (e.g. for Facebook photos) all worked. Just from time to time i would get the occasional (mildly annoying) message on my computer saying "scan to computer is currently unavailable" but it usually worked itself out and whenever I needed it to work, it did work.
But since a few days ago, it has some severe connectivity issues. I didn't change any settings on the printer, router or computer - the issues just started appearing by themselves. I startet getting much more frequent messages on my computer saying "scan to computer is currently unavailable". I noticed I couldn't print anymore, and restarting computer, printer and/or router didn't help at all. The only thing so far i managed to print wirelessly since the problems started were the first 5 pixel rows of an image I tried to print, the rest didn't transmit.
It seems the printer still connects to the WLAN but printing and scanning no longer work, and whenever I try to access a web service on the printer (like Facebook) it says it has no internet connection, even though the WLAN light is lit up (not blinking) and all the wireless status reports say "congratulations, no problems found" and display IPs etc. just like normal.
I looked at the threads "PhotoSmart 7510 connects to router, but not to the web.", "Wireless printer (HP Photosmart 7510) not connecting to network" and "Photosmart 7510 won't connect to Web Services" but they weren't a big help. Activating EWS didn't work because even though the printer showed its IP address to be 192.168.1.3, when I entered this in my web browser it didn't find the printers configuration page.
I tried the following steps from one of the threads:
1. Restore the Network defaults
2. Unplug the printers power cord while it is still on. Leave it unplugged and walk to the router.
3. While the router is still on, unplug the power cord from the router, leave it unplugged for 30 seconds, then reconnect the power cord to the router. Once plugged back in the router should power on automatically.
4. Plug the power cord back into the printer. Once plugged back in the printer should power on automatically.
5. Run the Wireless Setup Wizard to reconnect the printer to your wireless network.
6. Try enabling Web Services.
I followed these steps exactly. Interestingly, even though I had done step 1 and restored the network settings to factory defaults, after turning back on, the printer somehow still had its old settings saved and reconnected to the network.
It seemed to have fixed the problem, the printer finally had internet access again (Facebook app showed my photos) and scan to computer found my PC. But after just about 3 minutes, the printer had lost its internet connectivity again. When opening the Facebook app, it displayed the same error message it did before. And printing no longer worked as well.
So, what is wrong with this printer?! It has the newest software update by the way (I checked during the 3 minutes it had internet access.) My computer is a HP Windows 7 x64 machine (EliteBook 6930p) and the router I'm using is a Netgear WNDR3700.
I specifically bought this printer for my studies at university. In one week i have my exams and in order to study I REALLY need to be able to print some of my course materials! So any help as quickly as possible would be greatly appreciated. Or do you think this is a case for a warranty replacement, considering the printer's really strange and error-prone behavior?
Thanks a lot!

I can assure you that it is not a router issue. It appears to me that it is a driver compatibility with Windows OS. After trying to get to the bottom of this since my Photosmart 7525 was new and reading just about every forum and blog, I have come to the conclusion that the issue must be related to the HP driver itself.
The issue does not seem to affect any Mac systems, and from one forum someone was able to fix it by downloading new drivers compatible with 64-bit systems (which seem to not be affected by the glitch). But that leaves us 32-bit people stuck with the current driver which does not work.
The printer is connected with good signal to the wireless router (no matter who's router it is and what configuration is made). The printer can be pinged from the router and any computer on the network which is not currently being affected by this issue. However, the affected computer fails pings by either request timed out, or destination host unreachable. Pings are successful from the affected computer to any other device on the network. The only way to recover (at least for a few days) is to reboot the affected computer.
Also, from the display on the 7525, the network tests pass without issue. I can also download and print content from the internet with no issues.
Please do a quick google search of this issue and you will see several THOUSAND entries of people with the same request. This is a serious issue that people are having and everything is pointing to an HP problem (not routers, improper installation of software or drivers, etc...). I agree with several other customers that HP should be on the hook for this fix. I will give it another couple weeks, then back to the store for a reliable unit from another competitor (Canon, Lexmark, etc..)
Thank you in advance for escalating this issue to product engineering,

Connection doctor and connection issues

I have nothing blocking my internet connection, however mail is a nightmare for me. I continually receive connection issues via the connection doctor for imaps, pops, and icloud.
Are my settings wrong? I have checked with each of the settings and they are set per instructions provided. Some are google, some yahoo, icloud, etc.
This is really annoying and I could really use some help.
Here is a typical message: Could not connect to this Google IMAP server. Check your network connection and that you entered the correct information in the Account preferences. Also verify that the server supports SSL. If it does not, deselect the 'Use SSL" checkbox in the Advanced tab of Account Preference"
I have done all of this and am still having troubles.
I am also receiving SMTP connection issues - "Trying to log into this SMTP account failed. Verufy that the username and password are correct."
I have checked and all are correct. Even more confusing, these issues are not present all the time - however I have not changed anything between when times are good and bad.
Sigh - I hope someone has an idea to help me out.
Thanks in advance for your time and thoughts.

Excel ODBC Connection Issues

I'm having some issues importing external data from an Oracle 9i database.
Here is what is happening:
I am initially able to import data from the table I want to into Excel.
I do this through "Data -> Import External Data -> New Database Query" where I have my .ORA data source. I'm able to log in using my user and password and import the table. My problems come after I import this first set of data.
If I try to "Edit Query…" I get an error box that says "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".
If I try to "Refresh Data" I get two error boxes. The first is just: "[Microsoft][ODBC driver for Oracle][Oracle]" and the next says: "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed". It then prompts me for the User name and password of the DB I'm connecting and after I enter the information, I get the same two error messages.
Also, if I attempt to establish another connection following the "Data -> Import External Data…" steps I run into a different problem. Upon entering the information for the User Name and password prompt I get two error messages. One says "!" and the next box says "Couldn't read this file". Once I click "OK" in those boxes, the Microsoft Query window automatically opens with nothing in it.
I can't seem to figure out why I can initially pull down data and then cannot succeed afterwards. I'm unable to connect to the DB I have through Excel until I completely closed all Microsoft Excel instances.
I also use this data source in Microsoft Access without any problems.
My Excel version is 2003.
I'm using Oracle Drivers I'm using are from an "Instant Client" package.
Any thoughts why I'm having these connections issues?
Thanks in advance.

This issue is closed.
The solution was:
"Data -> Import External Data -> Import Data"
Select "New Source" and select the "Oracle" data source and filled in the appropriate information. This was similar to the database query but it actually works.
