DNS Slowdown
Clients on my network have been experiencing DNS issues, starting about two weeks ago, that I've yet to resolve. Users will frequently get an "unable to find server" message on the first attempt at loading certain websites; this is usually resolved by reloading. On the server side, I'm getting tons of messages like the following:
15-Mar-2010 11:52:50.122 host unreachable resolving 'www.nature.com/AAAA/IN': 2001:503:a83e::2:30#53
As mentioned, everything was working fine a couple weeks ago, and nothing has changed about the server's configuration.
DNS services are configure to support one local zone, and all other requests are forwarded to our school's DNS server for resolution.
Thanks in advance for any help you can offer.
Jeff
My apologies. It was not my intention to obfuscate useful data, simply to obscure the actual IP address (primarily for the upstream, non-local DNS server) in order to avoid "you shouldn't post identifying information about your network online" responses. So, below are a number of unaltered attempts run from a client system. Note, the client only knows about one DNS server (192.168.250.2) directly, and that server has authority for only one zone with one record (ixd.sva.edu / ixd1.ixd.sva.edu). Other requests are forwarded to the upstream DNS server, 172.27.128.246. This is all configured through the Server Admin GUI.
All digs below are run from a client system. Please note, since last running dig I've added <<listen-on-v6 {none;};>> to the options section of the named.conf file on my server, and restarted named; this hasn't resolved the issue, and I still get multiple "host unreachable resolving" messages about IPv6 addresses.

I hope this is more useful and can shed some light on the issue. Thanks for your help and patience.

Hi,
There have been a couple of post regardig slow Safari. I am also havin the same problem. One on the posts had mentioned something regarding DNS. When plugged in directly to cable modem it seems to run ok. When through a DLink router, I have slow down.
Because I have dynamic IP, my service provider can not give me a server DNS to enter.
Any suggestions?
I do not have these problems with Internet Explorer running Windows on the same Mac.
Any suggestions?
Thanks,
CraigThanks,
But I still seem to be having problems. Takes a couple seconds to find the site. Once it gets going things are pretty fast.
The same thing happens with Firefox too.
Download speek is pretty fast once it is in process.

Extreme slowdown of internet (appears to be DNS lookup)
Within the last couple of months I have been having issues with extremely slow internet access. I haven't really been able to pinpoint a cause of the issue and AppleCare was not able to come up with a fix other than to wipe the hard drive and reinstall OS X, which I'd rather not have to do.
The symptoms are:
Very slow to connect to anything on the internet (AIM, mailservers, websites). When I try to visit websites in any web browser it takes anywhere from 10-30 seconds for the page to even begin to load (in the status bar it says "Contacting [web address]").
I was initially only having this issue with the LAN connection at my university, so I set up a wireless access point on my network connection, that resolved the issue temporarily, now the same issue is occurring on that WLAN conneciton.
I can connect to other people's LAN and WLAN connections on campus and there is no speed issue.
I also was not having any issues at home on both our WLAN and LAN connections until last weekend when it all of a sudden slowed down all of the Macs on our networks. The issue didn't seem to appear at home until a personal file sharing share on my iMac was incorrectly disconnected from my MacBook Pro. Immediately after that incident all Macs (iMac G4, Mac Mini G4, MacBook Pro Core Duo) on the network have had the internet speed issue.
I've noticed that Windows machines (including the Parallels Windows virtual machine) on the network are not affected. So this brings me to think that there is some sort of issue within OS X...but I don't know that much about the underlying technologies that run OS X.
Is there any advice/support that someone can give me?
Thank you!

MacBook Pro 17" Core Duo Mac OS X (10.4.8)Hi Camelot,
Thank you for taking the time to help me with this issue.
I did run the nslookup command and it did take a few seconds for a response. (results below)
I checked the network configuration of a Windows XP machine on my network and it is just set to obtain a DNS server automatically, no servers appear to be set.

Slow browsing, not a DNS issue
Hi
I have a late 2013 MacBook Pro 13" and browsing on my home network is ridiculously slow (5 mins to load a page, if at all). I've tried all the fixes related to DNS and have changed to OpenDNS and Google and back again to no avail. Both my iPad Air 2 and iPhone 6 work smoothly and with lightning speed on the same wifi connection (Australian National Broadband Network, speeds c. 25mbps).
Neither Apple Diagnostics nor the "Assist me..." diagnostic available in Network preferences yield any data on potential problems, indicating that everything is working as it should be.
Any ideas??
cheers,
A1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
Part 1 of 8 done at … sec
Part 8 of 8 done at … sec
The test results are on the Clipboard.
Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

I've have not been able to view web pages since Monday evening. I called the Tech Support line and was informed by a message that there was a major problem in my area though I was informed this had been cleared when I called the following morning. My problem however is still ongoing.
The issue seems to be DNS. If I change my PC DNS to use 8.8.8.8 and 8.8.4.4 or VPN into my work network there are no issues and speed seems fine. I cannot however change DNS Settings on the HH3 which is used for other devices. When using the HH3 DNS some pages will partially load (cached maybe) but the majority are unreachable.
Calling tech support last night was not much help and they have set up an engineer visit, though this is not until Thursday and I'm not sure it will help as I suspect the problem is within the BT Network. Does calling tech support initiate any investigation at the network side?
I am on Infinity 2 upgraded a few weeks ago. I am in the 02085 area (E15).Your PC DNS settings should overide any changes to DNS in the HH [or any router].So if the DNS set in your PC settings works with all sites then there is no need to change router DNS settings.
I have 3 servers and my main PC all using different DNS settings and they all connect to the internet with no problems.
To find out whuch are the fastest most reliable public DNS servers nearest to you,run a DNS optimizer program and the use the fastest and most reliable ones.
Some DNS servers even the most used ones like OpenDNS,use a referal system that kicks in to allow referal to there own or outside advertising sites,but no big deal as it only kicks in if you wrongly type a URL.
But it still causes slowdowns,so your choice of DNS is important to a fast stable connection. -
Hello,
For the past few days, I've been getting a real slowdown in Safari 3.2.1 again - I was getting this on my old iMac G5 running Mac OS X 10.4.11 after upgrading it to 10.4.11 and to Safari 3.2.1 in early December. That iMac G5 is gone now.
I got a new iMac 3.06 GHz Intel Core 2 Duo about three weeks ago and Safari has been fine up until a few days ago. I go to sites and they take forever to load. Then I empty the cache or do a reset safari and try again and sometimes, it works ok for a while and then back to the same thing - websites take forever to load.
It's not our network - our PBG4/667 running Mac OS X 10.4.11 and Safari 3.2.1 seems to work fine all the time. It's just my new Intel iMac that has this problem. The only thing that has changed in the past few days is that I installed iLife 09 and it automatically installed QuickTime 7.6 (from the previous 7.5.5). Nothing else has changed on my new iMac. I still haven't installed the iLife Media Browser Update 2 that shows up in my software update but I can't see how that would affect or resolve this problem anyway.
Does anyone have any suggestions as to what may be going on and how to resolve this problem?
Thanks very much,
Gerard208.67.222.222
208.67.220.220
are correct.
The following usually works on both Tiger and Leopard:
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
Click on Apply Now and close the window.
Restart Safari, and repair permissions.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
Less likely, but possible, is that the slowness is caused by a Trojan such as the one called 'DNSChanger' or 'OSZ.RSPlug', which can alter the DNS settings of your network connection. This particular Trojan can be inadvertently installed if you have come across certain Quicktime movies where got a window stating that you have to download and install a particular codec in order to see the video.
If you have agreed to that installation, your system can be infected and your DNS settings altered, which results in your system using the wrong DNS servers, which can slow web surfing to a crawl.
This can be fixed by downloading and running a freeware utility called DNSChanger Removal Tool which you can download from here:
http://www.versiontracker.com/dyn/moreinfo/macosx/33696
Once you have run that utility you have to re-boot your Mac, then reset Safari, and re-enter your DNS settings in System Preferences/Network. -
10.6.5 and network connection slowdown, flakiness
Ever since the 10.6.5 update (applied via Software Update), I've been plagued with a very severe slowdown in my internet connection. Typically, when connecting to most websites, in the Firefox status bar, I get a lot of "Looking up..." "Waiting for..." Connecting to..." Transferring date..." messages. Often, it can take 10-15 seconds to load a website. For instance, it took a good 10 seconds for the Apple Support page to load (linked to from the Apple homepage.) I'm seeing this sort of activity both with my router between my modem and my iMac, or with the modem directly connected to the iMac (with the Firewall enabled when directly connected.)
Additionally, I've had instances where, if I leave the iMac alone for a few hours, the internet connection itself will drop, and I have to re-boot the iMac to get the connection back. If a user account is up and, say, a browser or mail is running during that period, those apps will lock-up and have to be force-quit.
And, after the iTunes 10.1 update, iTunes seems to need to rebuffer all streaming audio on an annoyingly regular basis. Like, every 30-seconds to a minute.
This is NOT a wireless network.
I've rebooted the iMac, router, and modem several times and none of it seems to help. DNS settings on the router and the iMac match (currently, Comcast's opt-out servers. When this problem started, I was using OpenDNS servers)
Anyone else experiencing similar problems after the 10.6.5 update?I too often have a devil of a time connecting to a Linksys WiFi router with a brand-new unibody MacBook Pro 15", 2.66GHz. I noticed that if I boot the machine off an external Firewire drive this seems to be more of an issue than if I boot off the internal drive.
I beginning to thing there's some kind of interference between the Firewire system and the WiFi system.
The router is a Linksys with the latest firmware update. My MacBook and iPhone 3G, iPhone 4 connect to the router fine. -
Why the response is very slow when the DNS enrty of server PC is remov
Hi
Though this subject has been already discussed at many places,im unable to get the clue.Here is my problem.In my office (LAN),server and client are running at different PC.After DNS entry of server PC is removed from DNS server,the page loading and every request & response between client and server is very slow.It takes 2 minutes for each and every request.And coming to the possible solutions,is "configuring the server PC in DNS server" is the only solution?When both the server and client PCs are DNS configured i dont see any issue or slowdown.Any help would be really appreciated
Assuming it is a lookup issue,i have written the following test application.
public class DnsName
public static void main(String[] arg)
String ipaddress = "";
String hostaddress = "";
if(arg.length == 1)
ipaddress = arg[0];
else
System.out.println("!!!!!!Usage : java DnsName <ipaddress>");
System.exit(0);
System.out.println("Time before processing : " + System.currentTimeMillis());
try
hostaddress = (InetAddress.getByName(ipaddress)).getHostName();
catch(UnknownHostException uhe)
System.out.println("Exception occured " + uhe);
System.out.println("Ip address : " + ipaddress);
System.out.println("Host name : " + hostaddress);
System.out.println("Time after processing : " + System.currentTimeMillis());
When it was compiled and run on a linux PC,time difference betwwen process is around 50ms,but when the same application is run in a Windows PC,the time difference is around 4-5 seconds(4000ms).Can anyone tell me what makes the difference in Windows??

www.adventnet.comBecause it does a DNS lookup. And without a server, the interface must wait for a timeout.

www.adventnet.comWhen you do getHostName() on an InetAddress, what you're doing is asking the OS to do a reverse lookup. So basically this is a windoze problem, not a java problem (although that probably doesn't help you much) Try searching google to see why a windows reverse lookup might be so slow and go from there.

Severe Site Slow-Down with multiple DNS/Sites
Alright.. this is a bit of a strange situation, any help is appreciated because I'm pretty much out of troubleshooting options.
Mac OS X Server hosting a few important sites and then several "redirect" sites.
- A PHP/MySQL system
- 2 normal PHP/MySQL websites
- 8 Redirects (domain.bz, domain.biz, domain.name, etc..)
The redirects are set up like so:
- A DNS entry with a "www" alias pointing to the local machine.
- A site with a .html file containing a meta-refresh to domain.com
The Redirects work just fine when they are enabled, www.domain.biz goes to www.domain.com, etc.. however, the 3 sites that run on the server experience severe slow-down to the point of not even loading.
Normally the sites are blazingly fast..
Anyway, if the redirect site entries are disabled, the slow-down disappears.
As an added oddity.. if Safari is experiencing the slowdown, but I cancel the site load.. the site pulls up missing images/css in varying degrees, depending on when I cancel, so it's like something is "hanging".
There's nothing apparent in the error logs other than a report that 'there is a mismatch between the domain name and reverse DNS' etc.. 'may cause some services to not work properly'.Nevermind, I found the problem.
The performance cache was enabled for the redirect sites. -
Can anyone tell from these logs if something is causing our major slowdown?

Add a DNS record using the relevant DNS snap in tool on the AD Server for the mac server as it should improve server and network performance. OSX and especially OSX Server is absolutely dependent on a properly configured and tested DNS Service running somewhere.

TC delays every DNS lookup etc by 10-15s?
When I initially bought and explored the settings of my 500GB Time Capsule, already running firmware v5.3.1, I found I could do more advanced stuff with DHCP and NAT than I could with my SpeedTouch DSL router, so I decided to try and offload those functions to my TC by disabling the relevant servers on the router and putting TC into "share a public IP address" mode.
Everything worked, but web access slowed to a crawl; I'd see a delay of at least 10-15 seconds per page or lookup request before the page would load at normal speeds. The delay wasn't even associated with a backup-in-progress, which was my first suspect. I stopped short of reconfiguring my DSL router's IP routing to point directly to Time Capsule.
I've now put the DSL router back in charge of DHCP+NAT functions, but am seeing no speed improvement to TC's wired or wireless clients. Only when plugged directly into the DSL router will a computer access the Internet as normal. My Time Capsule replaced an old Airport Extreme Base Station and a 4-port gigabit switch, but it feels like I've taken a step back in terms of speed and convenience.
Current setup is as follows: my Time Capsule plugs directly into my DSL router and operates in bridge mode. I have an AirPort Express in another room operating as a WDS remote, and my Mac mini (as well as my PowerBook on occasion) plugs into Time Capsule. I've experimented switching TC between using my DSL router's DNS server and using my ISP's DNS servers, but no difference. Wired and wireless clients of TC are still experiencing the same slowdown problem, and I can't think why...I see a very similar issue, but it's been occurring on my laptop for 4 or 5 months, which must be way before 10.6.4. My roommate and friend's laptops all work fine on my network. And my laptop works fine on anyone else's network. But MY laptop on MY network always gives the abysmal DNS performance as described in the original post: 40% of requests time out. Wireless or wired, it doesn't matter. Exact same behavior.
It also doesn't matter whether I use my Netgear router as DNS server, or my ISP, or OpenDNS, or Google. Exact same behavior.
When I do a network trace, it looks like most DNS requests my computer sends out simply never get responded to. (Could they be malformed when they hit the wire? I don't even see an error reply) A few make it through. And when there's a IPv6 (AAAA) record sent, my computer returns a "port unreachable" ICMP message. A screenshot of all of this dialogue is here:

I recently had opportunity to cancel my cable service, and reinstate it for a lower price. They came out, tested the line (strong signal), gave me a new cable box. Yet the issue persists. Exact same behavior.
Firewall is disabled. I've deleted the network interfaces and added them back. Nothing helps.
(As I recall, this issue may even have been present before I reinstalled 10.6 over 10.5, so I'm not too confident a total reinstall would help.)
Any help? I'm about ready to buy a new laptop to fix this damned problem. Web browsing is nearly impossible, as is. -
Comparing Apples to Apples, Leopard is SLOWER in Internet Speed Access than my old Tiger 10.4.10.
Doing a speedcheck under Tiger gives me a 7341 reading...but my same system under Leopard comes out to 3431.
Why the slowdown and apparent internet slowdown with the same exact hardware/airport/cable modem?
Also, my Airport Signal strength in Tiger is a full 4 bars..but with Leopard it's only 3?
Something in Leopard isn't handling things the same.
Between email issues and internet access...I may stay with Tiger until 10.5 is fixed.if you haven't I would encourage you to add specific DNS servers for your ISP as Erik suggested - that fixed my problem when nothing else would
Try Erik's solution - it fixed internet access for me -- in this thread -- http://discussions.apple.com/thread.jspa?threadID=1225208&tstart=0
Larry:
In my case, this is an issue with the DNS Server. In my set-up, I had a G5 with intermittent access, and a MacBook Pro & iMac G5 with no problems. There is only one difference in the configurations. The MBP and iMac had additional DNS addresses added into their network configuration from my last ISP. I had manually entered them, and never removed them. When I added the same DNS Servers to the G5, problem solved. When I removed them from the MBP, problem appears. This was not an issue in Tiger, and although I'm not sure why, I have determined a few other workarounds and contributors.
First, in the Network Preferences, you can hit the Advanced... button and click the DNS tab to see your DNS Servers. Likely, you only see 10.0.1.1 or something similar which means the computer is getting DNS info (routing to internet servers) based on what the Airport Extreme/Express or other wireless router is sending through DHCP. If you have the actual DNS Server addresses from your ISP (or any ISP) you can add them here and probably fix your problem. Add them and click OK, followed by Apply.
Now to the root of the problem in my case. By opening the Airport Admin Utility, and selecting my base station and clicking on the Internet tab, I can see that my Base Station is serving up two DNS Servers. One is it's own router number which falls into the 192.168.xxx.xxx range. I know this isn't a valid number. The second is the actual number from Cox (my ISP).
So when the computer relies on DNS info delivered through Airport using DHCP, it is getting a bogus number first, but it keeps trying. Eventually, it might look at the 2nd option, which explains the delays. If you enter the DNS info directly into the System Preferences, it seems to ignore the DHCP version and go right to the site you want.
Check with your ISP for a list of DNS Servers. Any server will work, just be sure it is from a reputable source. If your Airport shows two servers like mine, use the Network Utility to do a look-up on the non-192.168 number and see if it comes back as your ISP. If so, then you can probably just insert it as the first server on the Airport or add it to the Mac with the issues.
I hope this makes sense and addresses your issue. It sure did help with mine.

Experiencing 2 kinds of Slowdowns with WRT300N
Hi i have newly installed my wireless router WRT300N it has the standard options on.. With a ppoe internett connection.
Problems:
1.When a person downloads using wireless on the router(not using even close to full bandwith) all the other users connected experience a 90% slowdown on the're internett connection.
Is this normal? with a wired router this has never been a problem.
2.When using slower wireless netword cards then 54 mb/s the internett speed is reduced to 64k/64k instead of the full speed. while the ones connected 54 mb/s have full speed on there internett connection.
Is there a option where i can speed up the connection with this setup?
Thanks for reading any help would be great.I had 2.00.08 when i posted.. Tried upgrading the firmware to the one in the downloads section (2.00.13) But the upgrade got only to 20% and shutdown.. Trying to get the router reset to factory defaults now to get it to work... Functions only as a wired switch now.. With no dns service or gateway whatsoever.
Does anyone know how to reset to factory conditions without having the router setup page available?

Slow JDBC calls with wrong configured DNS
We recently found out that a wrong configured DNS Server can cause oracle JDBC Clients to react extremly slow. (1 second per simple sql statment)
We have found also that if the DNS server is disabled on server side (8.1.7.1 Oracle, Redhat 6.2 server) the system responds with normal speed.
It seems for us that Reverse lookups are done for any SQL Statement sent from the client and not only for the first connection.
Does anybody know how to disable this Reverse DNS-Lookups on Server side because this may also cause a slowdown if the DNS-Server is correctly configured or all clients are defined in /etc/hosts.
