Too Many Networks

I recently purchased a new Cisco router and set it up in the middle of the basement so more smartphones and tablets would get better wifi signals elsewhere in the house. The previous router was hardwired into the HP PC inthe far corner of the basement. This new router is set up for wireless connection to PC.
While everyone else in the house is enjoying quite good reception, the PC across the room was not! So I bought a TP-Link adapter and set it up to boost the signal to the PC.
Here is where the confusion begins. The PC shows two separate "networks"...one marked "Home" and the other marked "public." Apparently, the internal 802 card is connecting (?) to the Home network and getting usual lousy signal, while the Adapter recognizes the "Public Network" and shows a great signal! Adding to the mystery is the inability to designate as "home" or even "click on" the "public network" reference in the net sharing window.
1) Should I disable the 802 internal LAN CArd?
2) Is the TP-Link somehow setting up its own sub-network?
3) Why can't the PC join the same "network" as the other users?
What do I need to know about Dual Bands? Is this part of my problem?
Thanks

You cannot prevent neighboring wireless networks from appearing in the list shown under the Airport menu of your Mac.
See Choosing your preferred AirPort network - I hope this also works for people still running MacOS 10.2.x.
The fact these other wireless networks exist is not in itself a security problem. Just make sure your own wireless network is protected with 128-bit WEP security (the best option available to users of MacOS 10.2).

AE Network Won't Stay Visible -- Too Many Networks?

I just moved to a new apartment in Astoria, Queens, and was having trouble getting onto the new roommates' wireless network (and learned that one of the other roommates, a fellow Mac user, couldn't get on it either). So I bought a new Airport Extreme and set it up yesterday in place of the old Linksys router. This took HOURS, because I couldn't get a signal in the next room (where my computer is) strong enough to maintain a connection to the base station for long enough to go through the entire setup process. As it turns out, when I run MacStumbler, there are -- no joke -- TWENTY other wireless networks of varying strengths and visibility around me. I eventually got mine up and working, but ever since, I'm lucky to get 20 minutes of internet access before my iMac drops the connection to the network.
Here are the gory details: The network is on channel 1. The twenty networks around us are all on channels 6, 8, or 11. When I run MacStumbler, our network consistently has the strongest signal strength -- around 70, compared to the other networks in the 40s or 50s -- but it also appears very infrequently, only poking its head above the fray of competing networks once every couple of minutes. A couple of networks with weaker signal are much more consistent, almost never disappearing from MacStumbler's view. Ours, apparently, likes to play hide-and-seek. In general, when our network does appear for a moment, it's impossible to connect -- the Mac tries hard for a bit, and then gives me the password prompt even though the password is saved in my keychain. I enter the password, and the connection fails or is timed out.
The Airport Extreme (one of the brand new 802.11n ones) has to be set up in my roommate's bedroom, since he's on a paleocomputer without WiFi and must be jacked into it. The distance from the router to my computer is maybe fifteen to twenty feet total, with a closet and wall in between. The closet does have some metal fixtures (rods and hangers), but is mainly wood and fabric.
My computer is a 20" iMac G5. I have my doubts about its WiFi antenna to begin with, since I also have an Airport Express (which is not currently on the network, since I can't hold a signal long enough to get it rebooted and connected onto the network, otherwise I'd use it to improve my signal strength) which I tried plugging into the power outlet DIRECTLY BELOW my computer, and the iMac only registered a signal strength of about 80. At one point yesterday I did manage to get the Airport Extreme onto the network as a repeater, and was enjoying a reasonable connection until the two base stations lost communication with each other, and I haven't been able to get back onto the internet since.
I also have a Powerbook G4 which I wandered around the house testing signal strength with; I tried setting the Powerbook literally on top of the Airport Extreme, and got the same problem wherein the signal was exceptionally good -- 116 -- but only when it appeared, which was once every couple of minutes. Then it vanished.
I've also enabled interference robustness and changed my IPv6 settings to local-link only, per suggestions in another thread I was reading on Ask Metafilter, but those don't seem to have made much of a difference.
So: what are my options? Is there something I can do to make the network consistent, and not be playing this "I'm here, I'm not here" game? Is this likely to be a placement problem for the router, or more likely to be an antenna problem with my computer? For the record, I'm still running 10.5.1, as I can't get connected to the internet long enough to download any software updates. I just need some sense of what I can do to address this problem: could the router be defective, or is this just always going to be a problem because of the unbelievable amount of wireless traffic around me on the other channels? Do I need to give up and buy a really long ethernet cable?

With twenty wireless networks (and who knows how many 2.4GHz portable telephones) competing for radio spectrum, I think your ability to run a stable, dependable wireless network with a reasonable data transmission speed are slim to nil. An ethernet cable sounds like the best option.

Too Many Networks Causing Interference

Hi all,
I'm running a PB G4 and Toshiba Tecra laptop on a wireless AEBS + AE network using WDS in a first floor apartment. My signal strength throughout the house is usually full bars with the AEBS running at around 45-65 and the AE at 35-45 signal strength depending on what room I'm in.
Now, sometimes my network just crashes and I receive error messages on the PB and PC telling me that there was an error loggin on to my network or that the connection is incomplete, respectively. My only recourse is to unplug the base station (and AE) and replug it. Usually, this corrects the situation.
I think this is happening because I detect no less than 5 other networks in my area. There are four units in my building, and the building is part of a row of connected apartment buildings. Adding my AEBS and AE, this makes a total of 7 transmitters in this cramped area! I think this might be creating a wireless blitz.
FYI, before running my current configuration, I was using a Netgear wireless router with the AE as a client (to stream audio). I switched to the AEBS + AE in WDS config because I thought it would add greater stability and range--which it has. But it seems I might need to "power up" some more in order to fend off the interference from other networks. I realize that this might have bad consequences for those other networks, but something has to be done!
So, I've been considering boosting my signal by adding an antenna. Is this a solution? I'm also thinking about tweaking the settings for both stations through Admin Utility. Maybe enabling interference robustness on the AEBS, AE, and PB might help?
Please offer any advice on what you think the problem might be and what might be the best solution.
Thanks,
FC

I think this is happening because I detect no less

I don't think so. You'll increase your signal
level, and your noise level all together. But
your signal to noise ratio will reach a limit.
Exactly like what happens when you turn your radio
too loud because of the noise of your neighbour's
one.
I'm also
thinking about tweaking the settings for both
stations through Admin Utility. Maybe enabling
interference robustness on the AEBS, AE, and PB might
help?
Yes.
But more generally, like every wireless problem of
interference, you should first analyse it. You
should use a tool like iStumbler to identify all
the channels used by your neighbours.
Once you have identified these channels, and
their level of signal, you have to choose a channel
as far as possible of the most powerful ones.
In an idealistic world, you should choose a channel
3 channels away of all the channels used by your
neighbours. (e.g.: if channels 1, 2, 5 & 6 are used,
you may use channels from 10 to 14, depending on the
regulations were you're using a wireless network).
All interference analysis should first go through
this neighbour's channels hunt.
If you play randomly with your channels, you're
wasting your time, you may be disrupting your
neighbour's networks. And you will have to continue
this silly danse for a long time all together.

SAP JCo 3.0 - too many network connections

I have implemented a standalone JCo-Client which has to make multiple calls to the same BAPI.
Java 1.5
SAP JCo 3.01
Windows Server 2003
Now I have the problem that each BAPI-Call opens a new network connection (checked with netstat). I use a pooled connection, I have only one JCoDestination object and one JCoFunction object on which I do many function.execute(destination).
Under JCO 2 i used a ClientPool and didn't have the increasing number of network connections.
Any ideas how to solve this.
I add the rump coding so you get the idea:
String destinationName = "ConnPool";
Properties connectProperties = new Properties();
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "XXX");
connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, "5");
connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT,   "5");
createDestinationDataFile(destinationName, connectProperties);
int count = 0;
try {
    JCoDestination destination = JCoDestinationManager.getDestination(destinationName);
    JCoFunction function = destination.getRepository().getFunction("BAPI_NAME");
    if (function == null)
        throw new RuntimeException("BAPI not found in SAP.");
    do {
        count++;
        try {
            JCoStructure importStruktur = function.getImportParameterList().getStructure("IMPORT");
            function.execute(destination);
            JCoStructure exportStruktur = function.getExportParameterList().getStructure("EXPORT");
        catch (AbapException e) {
            System.out.println(e.toString());
    } while (count < 50000);
catch(JCoException ex) {
    System.out.println(ex.toString());
Edited by: Jochen Lang on Apr 29, 2009 1:30 PM

Further testing showed that Pooling connections doesn't affect the number of actual network connections generated.
But with encapsulating the numerous function-calls into a Stateful Connection via
JCoContext.begin(destination);
...lots of function calls...
JCoContext.end(destination);
only one network connection would be used. Sadly I can't use this in my actual application.
Your comments and experiences to this are appreciated!
Greetings Jochen

Iwlist scan fails when there too many wireless networks

$ sudo iwlist wlan0 scan
print_scanning_info: Allocation failed
wicd uses iwlist to scan networks but iwlist fails when there are too many networks. This seems to be an old issue. Is there a fix for this?
Thanks.

There's a fix yes. For wireless_tools-29 there's a patch somewhere. Or you install wireless_tools-30pre9

Attempted to set up an HP wireless printer and my whole network is now a mess. HP help told me I had too many signals, as I have a Time Capsule 4 Macs and 4 Airport Express set up. Anyone else figure this out?

I attempted to set up a new HP wireless printer. It is unstable and HP support says I have too many devices since I have a time capsule and 4 airport express either extending my network or being used for a different printer or stereos. Anyone else find that their Airport Express/Extreme interferes with a wireless printer. If so, what's the point?

I have a similar model, the HP 8500A here in the home office that I originally hooked up using wireless on an AirPort system consisting of an AirPort Extreme, Time Capsule and 2 AirPort Express devices.
The HP was originally hooked up to the "main" router using wireless as a test to see how wireless would perform. No issues with setup or performance over the first few weeks. I did eventually change the device to connect using Ethernet once I had room to move the device near the AirPort Extreme.
HP is pulling your leg with the advice about too many devices. The AirPort Extreme and Time Capsule will handle up to 50 wireless devices. In my case, I did nothing except follow the setup procedure and restart the entire network....something that I always do when I make any change to the network.

After Loading Lion I now get 5 windows w/ a graphic of a Red Stop sign with an ! mark and the following text message:
"DAVE Networking

I have uninstalled DAVE and used Clean App to remove trace elements of program, however I still get the message and am unable to eliminate the error messages. When I click OK the message goes away briefly and then comes back up.
Any solutions would be great.

Dave,
Thanks....What I did was load the free eval version of Dave 9.0 and then used the uninstaller which must have deleted the kernel giving me the problem.
Thanks for the response.

Entered wrong network unlocking code too many time...

Hopeing that you can help. My phone is a lumia 610 locked to the optus network. I accidentally entered the wrong network unlocking code too many times. The phone now blocks any sim card that I put in it. Asks for a PUK code. I got the PUK code from optus, entered it into the phone and it didn't work. I then took my phone into an Optusstore for assistance. They entered the PUK for me and it also didn't work. They then put other sim cards in the phone and it still asks for a PUK code. They tried entering the PUK code for these other SIM cards but it didn't work either. They then put these SIM cards in another phone to test and it worked no problem.
What's happened to my phone and how do I get it fixed?

The PUK code relates to the phone only. If you feel that the phone has somehow got "stuck" as you put it and want to try something yourself, then you could try the soft reset or even the hard reset. Note that you will loss all your data and settings unless you have a previous backup.

Does the ext directory have the php_oci8.dll? In the original steps the PHP dir is renamed. In the given php.in the extension_dir looks like it has been updated correctly. Since PHP distributes php_oci8.dll by default I reckon there would be a very good chance that the problem was somewhere else. Since this is an old thread I don't think we'll get much value from speculation.

Hi,
I'm Galit from the QE team of VIN.
All the things that you've described are correct.
It is actually an edge case where the only VM, that the manual App can be managed from its Map view, was removed from the App.
The Manual App management is as designed, and may be changed in the future.
There are 2 ways to overcome this situation:
1.You can, as you stated, create another Manual App with similar name and remain with the "Zombie App".
2. To run a specific command that will remove the Zombie App from the DB.
Please note that option no. 2 involves using an API that we do not publish.
If you would like to use option no. 2 contact me in private and we will see about supplying the relevant commands to run in order to delete the "zombie" application.
Thanks,
Galit Gutman

Router connection problems - DISH satellite receivers or too many devices?

(Sorry about that - I thought I had broken the message up.)
I'm having significant issues with my Linksys router timing out, and need help. I'll try to be as detailed as I can.
I have the following:
- Linksys WRT54G v3 wireless router I purchased off eBay 3-4 years ago. Using 128-bit WEP secirity. Even though the model says WRT54G, my Linksys setup page says I have a WRT54GL. Don't know if that's pertinent but thought I'd include the info)
- HP desktop running Vista Home Premium
- Gateway Solo laptop (circa 3Q 2002) running WinXP SP3, and also have WPC54G - Wireless-G Notebook Adapter
- Gateway M275 Notebook running Windows XP Tablet Edition w/SP3, internal wireless card
- Linksys WRE54G Wireless Range Expander, v3
My broadband internet connects to my cable modem, which then runs via ethernet to my router. I have my desktop connected to my router via (wired) ethernet cable (port 1), and the two laptops connect wirelessly. All three computers on my network run just fine and have had no connection issues until I had two (2) DISH satellite receivers installed this past Friday.
Prior to installation, I knew I would need the two receivers hooked up to my network via ethernet cable. Since one receiver was in the same room as my router, it was easy to run an ethernet cable from my router to the receiver (port 2). I had a challenge with the upstairs receiver, because I didn't have a direct connection, and wasn't sure how to wire it. So, I used my range expander by plugging in the expander into a nearby outlet, then connecting the receiver to the expander via ethernet cable.
I had some issues getting a good signal, and did some troubleshooting but made it work. Now I had five devices connected to my router: two with a wired ethernet cable and three wirelessly.
I started having connection timeouts within about 3-4 hours of satellite [receiver] installation. All of the sudden I couldn't connect to the internet on ANY device; both laptops couldn't connect wirelessly, my desktop couldn't connect, and the receivers were telling me my connection was bad. I checked modem but there were no issues. Still, I unplugged the power cable from the modem for a minute, then reconnected - still no internet. I called my cable company to have them troubleshoot the modem, but they pinged it several times & got positive results - still no internet, so I ruled the modem out.
I tried using the Windows connection troubleshooter to repair the problem, and got a DNS error message (which I don't know how to fix). I decided to unplug my router for 10-15 seconds, then plug back in - that got my internet connection going again. That lasted a couple hours & then failed. I unplugged the router again (is that a soft reset or a power cycle?), then reconnected & was able to connect to the internet. This happened a few more times over the weekend, and finally I decided the expander might be the issue (both DISH and Linksys tech support was not very helpful).
I found a way to wire my second receiver via ethernet cable (port 3), so now I had three wired devices, and two wireless devices. I thought this would fix the problem; it didn't, but at least I learned how to wire CAT5 cable. So I got that going for me... which is nice.
I plugged the ethernet cable directly from my modem to my desktop to test the timeout, but had no issues - the modem just wasn't the problem.
I was getting some IP address conflicts on my Norton Inernet Security, so I uninstalled that from my desktop, disconnected the power from the modem, disconnected the power from the router, shut down all devices, reset the IP addresses on the receivers, deleted the wireless connection from the laptops, shut down the desktop, and just left the whole mess alone for half a day. Then I reinstalled the Norton Internet Security, connected my wired devices, plugged the modem in, plugged the router in, reset my security, connected wirelessly with my laptops.
Within an hour my connection timed out.
Trying to chat with tech support wasn't feasible, as my connection kept going out. A guy at work said I shoudl ping my IP address, and let it repeat until my connection goes out. So I unplugged the router and plugged it back in to get an internet connection, the opened a cmd prompt and typed
ping 192.168.1.1 -t
I left it alone for a few hours, and when I came back, my internet connection was down, but I was still getting active pings - no problems there.
At this point I thought I had done everything except replacing my router (which I'm still tempted to do), but I called my broadband provider to see if there was anything they could do. One of the techs said I had too many devices connected to the internet, but I thought these routers were supposed to handle dozens of devices?
I finally called Linksys Tech Support and had a conversation for 90 minutes. We went through all the steps of unplugging the the modem, router & all connected devices, resetting the router, etc, etc. The only thing different he did was had me change my security from WPA to 64-bit WEP, and added passwords for DNA1 and DNS 2 (same password for each).
That was at 1:30am last night, and when I woke up to check my connection this morning, it was still connected. I have to check it again when I get home, but I'm wondering if I should just be prepared to get another router (and if so, any recommendations), or if there's something I'm still not doing that could resolve my issue - if I still have connection losses.
Also, I'm concerned about the security thing. If changing from WEP 128 or WPA to WEP 64 fixed my problem, I'm not sure I feel completely protected from intrusion - isn't that pretty much the least amount of security I can have (without forgoing it altogether)??
Finally, I've read a few threads suggesting possibly changing to static IP from DHCP; however, my satellite receiver installation documentation specifically advises against this for the receivers.
Anyway, I would very much appreciate some help.

I have an iPhone 4S I have done the recent update 6.1 and now my App Store is not working when I go into the feature tab I get an error " too many HTTP redirects" how do I fix this ? The other tabs are working and it is working on my iPad also

I am having a problem getting into the App Store on my iPhone since the recent update, I have a 4s and it appears the feature tab is not working. When I try to go into the feature tab in the App Store I get a message "too many HTTP redirects" ?... Does anyone now hoe to fix this issue, the other tabs are working okay and everything is working on my iPad ?

Additional things to try.
Try this first. 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.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Slow system and too many details after upgrading to OS/Lion

This MacBook Pro is my right hand, I was doing so great with Snow Leopard, Now everything takes twice longer. I cleaned up, reseted, reinstalled softwares, etc. same.
Too many details that doesn't work correctly.
-Safari constantly needs to be loading. Some times Firefox.
The track pad cant keep open a display box with a long list, once you try to scroll down.
-Preview, i used this app a lot, safe me time, DUPLICATE? instead of SAVE, i don't see the purpose. After editing images and safe them, gamma, color patterns and light appear distortion.
-iTunes volume doesn't comeback after using Skype or another app, remains low.
-Airport takes a bit longer to find a local network.
-There is not an extra space for the left and right scroll bottom on the finder window, sometimes this one disappear but mostly remains which makes it pretty tricky to open the last file at the bottom of the list. because the scroller is on front.
-External Drives, takes longer to connect or disconnect them.
Suggestions before i reinstall Snow Leopard.

guizz,
it sounds like you have come across the mother of all problems but i would like to help as much as i can.
first of all, i noticed that it took a few days after installing lion before my system was back to the full stride it had while running snow leopard give it some time and a few updates and lion should speed up because components such as ram take time to adjust.
the duplicate thing in preview is a new thing that came out with versions, one of the many new features in lion. i think it takes the place of the SAVE AS... command and you should still be able to save using the old command-s keystroke however part of lion includes an autosave feature so you really never have to worry about saving your work.
i personally cannot speak for safari or firefox even though i have both because i use google chrome as my web browser you can always give that a try.
in the system preferences under the general settings option you can change how the scroll bar is displayed on the screen.
i would suggest searching for other people who have had similar problems with itunes to try and find an answer
as for everything else your system may just need time to adjust to lion
good luck hope this helped a little

Too Many Attempts?

I've just moved onto a new wireless router/network at home, and I can no longer connect to iChat wirelessly. All other internet applications work, but when I open iChat, it logs on, immediately logs off, and does it again and again until I get an error message saying that I've attempted to log in too many times in too short a period, so try again later (and all of my buddies are gray-ed out). Is there a fix for this? Or it is something wrong with my wireless router/network?
Thanks in advance!!!
