N95 8BG "WiFi Connection problems" and "Web: no ga...

Like many users, I could not get my new Nokia (N95 8GB) to work with my WiFi. After many attempts, using the various ideas posted, I came up with a solution that works reliably for me.
First lets deal with "WiFi Connection problems"
Menu/Tools/Settings/Connection/Wireless LAN
'Show WLAN availability' = 'Yes'
'Scan for networks' = 'Every 5 minutes'
Some users have suggested choosing 'Advanced Settings' from the 'Options' menu, changing 'Automatic configuration' to 'Disabled' and the either setting 'RTS threshold' to '2346', or setting 'Power saving' to 'Disabled'. I tried both of these but they did not make any difference in my case. However they may make a difference for you, hence their inclusion here.
Menu/Tools/Settings/Connection/Access Points
Choose 'New access point' from the 'Options' menu
'Data bearer' = 'Wireless LAN'
'WLAN network name' = If your network is set to broadcast its SSID, use 'Search for networks' then select your network from the list, otherwise use 'Enter manually' and type in the SSID.
'Connection name' = anything you like, but I use the SSID
'Network status' = not sure about this maybe someone can confirm, but I think if the SSID is broadcast then it is 'public', otherwise it is 'private'.
'WLAN network mode' = match this to your access point configuration. Mine is set to 'Infrastructure', so I do not cover the ad-hoc scenario here.
'WLAN security mode' = again I am using WEP so have not covered other scenarios.
'WLAN security settings' = these should match you access point configuration.
'Homepage' = whatever you like. I use 'http://www.google.co.uk', just so that when I start browsing I get something reliable, useful, and dependable. If Google fails to appear it usually means there is something wrong with your config.
Now lets handle the dreaded "Web: no gateway reply"
Menu/Tools/Settings/Connection/Access Points
Scroll down to highlight the new access point and choose 'Edit' from the 'Options' menu. Now choose 'Advanced settings' from the 'Options' menu.
Assuming you network used IPv4, which most do in my experience, select 'IPv4 settings'. I don't know about IPv6, and don't use a proxy so these are not covered.
The values you enter in 'IPv4 settings', depend upon your network/router settings, and whether you have a DHCP server or not.
Assume your a router IP Address, on the LAN side, is 192.168.0.1, and that it has a DHCP server set to serve addresses in the range 192.168.0.64 to 192.168.0.192, using subnet 255,255,255,0. Since the mobile does not seem able to get an IP Address from the DHCP server we give it a static address 192.168.0.55. Notice this is outside the range sereved by te DHCP server to avoid conflicts.
We end up with:
'Phone IP address = '192.168.0.55'
'Subnet mask' = '255,255,255,0'
'Default gateway' = '192.168.0.1'
'DNS address' = 'user defined'
'Primary DNS address' = '192.168.0.1'
'Secondary DNS address' = '0.0.0.0'
I used something similar and was at last able to browse the web via wifi.
I hope all of the above helps someone out there.

I have just experienced this problem having been using the WiFi network for months without problems. I tries all the suggestions on these forums including the power settings, turning off WEP, and the fixed IP suggestion and none worked. I even reinstalled the firmware and reconfigured everything. It turned out to be the router. I had rebooted it several times to no effect but the DHCP always gave the N95 the same IP address lease. So I changed the range of IP addresses the DHCP could lease and restarted the N95. It got a new IP and was back working again.
If at first you don't succeed, try again. Then quit. There's no use being a damn fool about it.

  • New retina MacBook Pro - WiFi connectivity problems

    Dear all,
    I've recently purchased the new Haswell 13" retina MBP, and I'm having exactly the same WiFi connectivity problems the 2013 Airs had. I have a solid connection for a short time, and at irregular intervals it just drops out. All of my other devices are still connected and have no problems. I've tried with two different routers/modems, but the problem persists.
    Is this a known problem - with hopefully a software fix in the forseeable future, or do I need to return the MacBook?
    Many thanks in advance for your help,
    Nic

    I haven't got a Retina, but I do have the same wifi problem. And if you've looked at these forums, you'll see it's been going on for years and no one seems to have a handle on what the issue is. All I can say is if I were in your place I'd take it back and exchange it. You have the chance now, so take it.

  • IPad WiFi Connection Problems - WiFi Symbol Appears With Full Bars but I Don't Get A Checkmark?

    I was using the iPad one day and then all of a sudden it stopped connecting to the internet. The network at this hotel is very good and I've asked them about their router so it is not the router's problem.
    I go to the Settings and tap on Wi-Fi then I tap on the hotel network. After a few seconds, it says the network name beside the Wi-Fi tab and it gives me the WiFi symbol showing 3 bars. But then I never get the checkmark or tick saying everything is connected. I try going online and it says the iPad is not connected to the internet. I've tried an iPhone and it connected and got a checkmark in a few seconds. I've talked to the front desk and he took out his phone and showed me that he could connect, he even opened a page without any problems at all.
    I've been trying to find a solution for this for a long time. I've been searching Google over and over again. I turned Airplane Mode on for 1 minute, I've tried Resetting my Network settings, I've tried forgetting the network and reconnecting again, I've tried removing all restrictions from the iPad, I've rebooted the iPad A LOT, etc.
    So this is my problem for people who don't want to read the whole message:
    1. I can't connect to the internet with the iPad
    2. It shows the WiFi symbol saying its connected but I never get the checkmark or tick.
    3. It's not the router problem.
    4. I've tried other networks and it doesn't work. It just keeps on showing that loading circle right beside the network name.
    5. Do any of you know what this problem is? Or do you have a solution?
    Thank you for reading this and have a great day

    Since you are in a hotel, some of these are not applicable.

    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 or Channel 6 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.

  • Iconia A1-830 has a Wifi connection problem when it out to 3-5 meters

     I bought Aser Iconia A1-830 in BestBuy and after 10 days I found out the Wifi Connection problem. If you stay close to router (1-3 meters) the WiFi signal is Good (not excellent). If I go to another room - Wifi connection is Poor or disabled. I changed it for another one (the same model). The second model was perfect only 1.5 months and now it has the same wifi connection problem. Can somebody help me? Maybe the problem in my router, but why it worked 1.5 months? 

    I'm not sure what the real reason is, but I do know it's a it of a hassle getting the connectors pushed back on. They are very tiny and take some pressure to install and I could easily imagine a wire not completely tied in place moving enough to work loose. Let us know how yours comes out.

  • Any wifi connection problems with new Macbook Pro 13" models?

    I currently use a 15" Macbook Pro (about 3.5 years old) that has intermittent WiFi connection issues (intermittently loses signal). This seems to have been a very common problem with this laptop model. My kids, who use Macbooks, have no connection problems. In any case, I'd love to buy one of the new model 13-inch Macbook Pro's but hesitate because of my many issues with WiFi connectivity on my older Macbook Pro. Just wondering if anyone is experiencing connectivity problems with the new model?

    I've never had Wifi connection problems with a Macbook and now with the 13" MacBook Pro I was flabergasted when I took my MacBook down the street to a coffee house with free WiFi. I went to connect to their WiFi and found my own WiFi connection listed. I thought this odd even though I was on the same block as my apartment, my apartment is six stories up. I connected to the Coffee Shop WiFi but it was really slow so I wondered if I could connect to my own home connection. I switched it over and lo-and behold I did connect! It was a good 300 feet away! I NEVER saw this with previously owned MacBooks including the black MacBook and the MacBook offered just before they moved the MacBook up to the Pro series.
    So I'd say they have improved the WiFi nicely.

  • Chronic Wifi Connectivity Problems

    My late 2011 MBP has been having chronic wifi connectivity problems ever since I got it, although I have really only begun to see the full extent. I bought it in late April 2012, so I am still covered by my one year warranty.
    Problems are as follows:
    Will not connect to certain areas. I am okay in my dorm, at my house, and several friend's houses, but it won't connect anywhere else on campus. (You can imagine that this is a problem.)
    I am running bootcamp on it, and the Windows side has no issues with connectivity.
    About every month, like clockwork, the wifi stops working altogether. It won't give me an IP address and the only solution is to clean reinstall OS. Which is getting very annoying.
    Additional Information:
    Within the first 60 days of having my mac, I had connectivity problems at a friend's house. Still covered by Applecare, they fixed my problem by renewing the DHCP lease and some other things that I can't remember.
    I took the MBP to a Genius Bar when the wifi completely went out and the only solution they had was to clean reinstall the OS. This involves completely wiping the harddrive and reinstalling, not reinstalling over top of what is already there.
    As you can imagine, I am extremely frustrated having to reinstall and restore my machine. I am wondering if these problems are preventable, fixable, or if my computer has a manufacturing problem that can be fixed under my warranty.
    Thank you for your help!

    Hey RJS568999,
    I found that if you can connect to your Wi-Fi router, but are having issues with webpages loading, sending or receiving email, etc., Apple recommends you use Wireless Diagnostics, included with OS X Mountain Lion v10.8.4 and later.
    You can read more about it here:

  • WiFi connection problem testing

    I am also one of many having the intermittent WiFi connection problem at home.
    From a technical testing mode. Get the free the "FreePing" application by Marcel Lanz in the app store.
    What you will find is when you are having the internet connection problem, you can not ping your Router. However, you can ping any wired Mac or desktop computer on your router/switch network.
    This tells you, you are on the network, getting an IP address from the router DHCP server.
    The problem is not related to the Wi-Fi connection or connecting to the network (OSI Layer 2 model).
    It appears to be a problem at the OSI Network Layer 3. The router is having a problem in the routing table. The hard part is the Layer 3 problem can be either in the Touch or the router in this configuration. Meaning, the combination of both Touch and router is causing the problem. Thus, the intermittent operation.
    Yes, this is probably more technical than anyone here cares to know.

    Hi,
    You should be debugging the driver / contact the vendor. Seems like netrtwlanu is realtek based chipset.
    The abort points to this driver (at least the PC).

  • Wifi connection problem better with full battery

    I have a macbook air I bought in 2012  (1.7 GHz Intel Core i5, 4 Gb memory) I know there are a lot of problems with other users complaining of wifi connecting problems. I have experienced the same problem but only when my battery charge is less than 98%. After my macbook has been on sleep for several hours, and has not been plugged in, the battery slowly drains and when I try to use it, it refuses to connect to any wifi connection. But as soon as I charge it up to 100% then it automatically connects, without having to restart it. Just wondering if anyone else has experienced this and if there has been any other answers from Apple regarding a potential fix for this issue....

    Try this and it should reset your printer.  On the front panel press the * and the # key at the same time, then press 1,2,3 in that order on the touch screen touch the left arrow button twice which will take you to the reset menu then press ok.  Press the left arrow two more times and it should say "semi-full reset" press ok and this will be performed.  The printer should shut down and will have to be turned back on, it will ask you for your language and your country the printer should initialize itself and should print an alignment page. NOTE: any speed dial numbers will be lost when you perform the semi-full reset.

  • Unending connectivity problems -- and Desktop Help...

    I'm wasting so much time on connectivity problems that it's positively wearying. Prior to the installation of BT Infinity here in April, I had a low quality broadband service because of the length of the line from the exchange: if I could get a download speed of 1.2Mbps and an upload of a quarter of that, I was doing well. 
    BT advised that thanks to fibre optic, my Internet should run much faster. So we had Infinity installed. I'm registered with Speedtest.net so am able to see my performance record.
    The average download speed is now aroun d 6Mbps and the average upload, more than that at 7Mbps. How an upload speed can consistently be faster than a download escapes me.
    But I'm not familiar with the ways of Internet connectivity and try as a I might, can't get my head around it.
    This desktop computer runs Vista OS. Vista was **bleep** when it came out and is renowned for its botched handling of Internet connections. So I'm not blaming BT for the literally unending connectivity problems that are occurring now, with line drops, speeds slowing to a crawl, and no guarantee that any connection will last. But it would be good to actually use BT software to help fathom out what's going wrong here, and today's typical morning which looks like this:
    1) Boot up computer. Automatic connection to hub via Netgear USB wireless adapter. Hub is on ground floor of this 3-storey property but signal strength from hub  is excellent, as confirmed by inSSIDer monitoring, currently showing 54 with no other networks anywhere near that figure.
    2) Perhaps 5 minutes after connection established, it's then lost. 'Local Only' is displayed. This is, apparently, a known Vista problem. But Microsoft has issued a fix for it. I know this, because it took 100 hours of ploughin g the Net to find out that MS had finally admitted to one more Vista screw-up. I've used the Microsoft router "fix it" before and it didn't work ("failed to process") so uninstalled it and have DL'd it again now and run it. This time it says it has fixed everything.
    3) Computer is re-booted to make the fix effective. Computer connects to Internet. Speedtest.net check yet again confirms that upload speed is faster than download speed.
    4) Connection dies. So much for Microsoft Fix It.
    5) Windows diagnostics reports that it can re-set the IP profile (or something.) I click yes. The re-set goes through. Connectivity is restored. 10 minutes later, connectivity is lost. Just a red X in the tray. No connection of any kind, not even that daft 'Local Connection' only alert.
    6) Reboot. Yet again. BT Desktop Help was installed here and ran OK when we were using our Netgear DSG34 router. But since the change to the BT Hub, the BT program has never run at all. So-oo. . . It has been uninstalled. And then re-DL'd and re-installed. And though the installation  has been completed, clicking on 'launch' has failed to launch anything. But anyway. An hour ago, in one of the brief periods today when the Internet connection was holding up, I Revo-ed out the earlier install, DL'd BT desktop Help and re-installed it. . . and I'm still at the same stage as always, with a  Firefox browser page that's open and completely blank and has been for the past 30 minutes. The URL is:
    file:///C:/Program%20Files/BT%20Broadband%20Desktop%20Help/btbb/Start.html
     Repeated page re-loading gets nowhere. Malwarebytes PRO is turned OFF to prevent any possibility of blocking and the antivirus is termporaily SUSPENDED. This PC runs on Windows standard firewall but even turning that OFF doesn't get the page to load. Copying the address into Internet Explorer in case there's a Firefox problem merely results in Firefox being opened and the same blank page running there.
    7) After all that. . . Connection lost yet again and this time, Windows cannot connect at all. It reports that the "wireless network security key is not correct". I happen to know that it is, because this is maybe the 20th time it has reported this in the past 10 days and every time I have to key in the "correct" key all over again. . . at which point Windows still says it isn't correct and cannot repair.
    Turning off the computer completely, unplugging from the wall, holding in the power switch for a full minute to clear the circuits, traipsing up and dowen three flights of stairs to turn off the hub, then wait, then turn the power back onm again. . . Ah, wot fun times I'm having here with my particular versioin of Infinity (as in, an infinity of connectivcity problems.)
    Summary: I seem to be being simultaneously hit with one issue after another.
    I'm bewildered as to why ever since Infinity was installed here, my upload speed is generally faster than my download speed. I'm not happy with endless Internet connection failures though am thinking that Vista is playing a large part here with its "wrong security key" and unending 'Local Only / Limited Connection' failures. I do miss my Netgear router and the ability to access a fantastic help menu and re-boot directly from the desktop without having to keep going up and down three flights of sdtairs to do so (I haven't been able to find out how toe access the BT Hub remotely.)
    Above all though: I'm  really tired of repeatedly trying to run freshly downloaded and installed BT Desktop Help software but getting no further than a blank page because the program has stalled.
    If anyone has any advice / suggestions, other than to buy a carrier pigeon, that'd be much appreciated.
    Thanks.

    Thanks again to John and gg30340. Here's an update:
    1) BT Desktop Help removed completely from this computer. The uninstaller itself mopped up everything, which surprised me. But anyway.
    2) Bt Home Hub manager set up and working. Had to input serial number and create new password. All of this sounds fairly easy and would be if one had the device near the desk. But the idiots who built this property shoved the BT master socket inside the garage next to the door. Our two home computers are on the third floor. To ensure the wireless signal strength is OK, the Hub and Infinity module/device/whatever it's called are on a high shelf. It's a major job to even reach the darn things, never mind read the labels seeing as how the BT Infinity engineer was good enough to tidy up the cabling and make a very tight connection to the wall socket.
    3) I had hoped to be able to back up the Hub's settings, seeing as the software provides for Advanced Settings / System / Backup. But not on mine (Hub 3.0). All that System allows is choosing which internet clock to define the accurate time. Everything else in System is just a pattern of short lines as if trying to indicate that there's some text there but it's invisible.This is now my second encounter with BT software which, for whatever reason, isn't functioning as it should on this PC.
    4) Hub reset to factory fresh, according to BT guide.
    5) Reset appears to have achieved nothing apart from requiring the password to be popped in again. After reset, it wasn't even possible to connect to the hub manager. Internet connectivity was eventually established for all of 30 seconds and then, gone.
    6) Computer was shut down and then booted anew. Internet connectivity is still. . . dreadful. One minute everything's fine and then, literally,. the next minute a webpage won't load. Even opening the Hub Manager has taken three attempts, i.e., disconnecting from the Internet, re-connecting, failing, and trying twice more until success. Yet all the time these failures are occurring, the tray icon is showing a steady, unwavering green icon for Local and Internet access -- despite the fact, there manifestly isn't any.
    7) Speedtest. net tests are actually showing upload and download 'trajectories' going slower and slower and finally halting at some point on the arc, then after a period of up to 30 seconds, suddenly becoming animated again. Speed test results with broadband speed checker UK and Think Broadband's checker are so at variance with one another, and with Speedtest, net, that it seems all three are using different technologies in pursuit of the same thing. Either way, upload speeds continue to be much, much faster than download speeds, a state of affairs I certainly have never encountered before.
    8) Speedtest net tests taken in the past 10 minutes, with one test following on from its predecessor, begin at 8.24 down/8.88 up, followed by 5.24 down / 6.40 up, followed by a mind-numbingly lonnnnng 0.62 down / 8.70 up -- in other words, a continuous yo-yoin g of Internet connectivity to the pooint that it actually might as well not even be here (I've had to make five attempts just to get on to this forum. . .)
    9) BT Speedtest will necessitate disconnection of everything downstairs and all boxes being lugged up here. This is actually going to require uncoililng tied-off cabling and hanging off a stepladder to do so -- though I surely can't be the only person in Britain who doesn't have a nice, handy BT master socket in their study or lounge. That said though: until we switched to Infinity, we *never* experienced these kinds of horrendous connectivity problems and never had need to unplug the Netgear router downstairs and bring it upstairs to connect directly to tjhe desktop PC so BT's own test could be run.
    I'll just have to get to work dismantling stuff tomorrow. However, I have to say that after a factory re-set which has changed nothing at all, I'm beginning to think there's a problem with the BT line itself (hence why I'm happy to follow the advice here, though less than happy at the prospect of the messing about involved.)
    Thanks, you two, for your patient help, and also for clarifying the situation re the three signal paths being shown on inSSIDer. At least I know that's usual now! And now, hopefully, when I press 'Post', I won't be faced with an endlessly spinning Firefox circle culminating in  what may well be, or seem to be, the 57,938th time today of seeing "Page Not Found". . .

  • N95 Wifi Connection Problem "No gateway"

    I am having a dsl broad band internet connection. It is connected to my desktop computer. I bought a new usb wireless (alpha). I would like to connect  n95 to the internet through the wireless which is coonected to my desktop.
    Thanks in advance

    I did like mentioned below
    Enable Internet Connection Sharing (ICS)
    rom the Windows XP desktop, click Start, Control Panel, Network and Internet Connections, and Network Connections.
    Right-click the wired network connection (this is your current connection that is used to access the Internet, the wired one), and then click Properties.
    On the Advanced tab, select the Allow other network users to connect through this computer’s Internet connection check box and clear the Allow other network users to control or disable this shared Internet connection check box.
    Click OK to save changes to your connection.
    Create protected wireless network shared through the ICS
    From the click Start, Control Panel, Network and Internet Connections, and Network Connections.
    Right-click the wireless network connection (this is your still disabled WiFi connection), and then click Properties.
    Click the Wireless Networks tab.
    In the wireless network adapter properties dialog box, click Add under Preferred networks.
    On the Association tab, type the name of your ad hoc wireless network in Network name (SSID). This is the name of the network you want to set, for example, I named mine Dotsisx as this is my nickname.
    Select the This is a computer-to-computer (ad hoc) network check box and clear the The key is provided for me automatically check box.
    In Network Authentication, select Open. In Data encryption, select WEP.
    In Network key, type the WEP key. The WEP key is a password that you are setting so that no one would access this network and make use of your bandwidth or data volumes. It should be a random sequence of hexadecimal digits or numbers, letters, and punctuation. Make sure you use something that you will remember easily, but that no other people in your surrounding might know
    In Confirm network key, retype the WEP key.
    Click OK to save changes to the wireless network and OK to save changes to the wireless network adapter.

  • Why won't Apple fix the wifi connectivity problem with the iMac and new OS instead of just havin us go through hours of useless mock fixes!

    I have spent hours with apple care about this problem with wifi connectivity.  According to all the posts I'm not alone.  I love my new IMAC
    but i'll be glad to go back to my PC just so I can get my email without all the headaches.  It seems that Apple has lost interest in
    the IMAC and all of the problems associated with the new OS. 

    Keep in mind that ASC is where people go to get help, so yes, you are seeing reports of people who are having WiFi connection issues. But while it might seem like there are lots of people having trouble, given the sheer number of iMacs in use, it is a very small number. Also keep in mind that WiFi isn't totally under Apple's control. There are dozens of WiFi routers. Even worse, the manufacturers of WiFi routers often release firmware upgrades to fix flaws without ever informing the consumer. And just to add to the confusion, while WiFi 801.2 n routers have been sold for several years, for most of that time there was no agreed upon standard!
    So if you'd like help, first, what router do you have and have you checked the vendor site to see that it has the latest firmware?
