      Intermittent Wireless Drop-out

      Hi all, I'm new here but I'm hoping someone has seen a problem like this before and managed to solve it, its driving me nuts!!


      I have a Netgear DG934G Sky router and since day 1 the only thing I have changed is the Admin password.


      I have been happily using the wifi for about 2 years with no problems however for the last 3 days the connection has been dropping out while browsing.


      Sometimes its for a couple of minutes then all comes back on, sometimes its for longer. Resetting the router either by power or by the reset button on the back makes no difference. I have even tried resetting to factory defaults. The only resolution I have is to wait for it to start working.


      During the problem times the lights on the front the power, the wifi and the internet all show as green regardless of actual performance.


      Sometimes the wireless signal disappears completely, other times I have a wireless connection just no internet connectivity (i.e. limited connectivity). Sometimes the SSID is being broadcast, so I can see and select it in my available networks list but I'm unable to connect to it, sometimes not.


      At any time during the wireless problems I am able to connect the laptop to the router using an Ethernet cable, I get an IP address and can see the Internet. So the router is running OK in that respect, I have an internet connection to the router which would also indicate the phone line is OK.


      I have spoken to Sky BB Support and after going through all of the above, they are sending me a new micro filter. Seriously...


      I have a number of devices available and all show the same symptoms whenever the issue arrises. The laptop are running Windows 7 and I have confirmed the problem with Andriod smartphones and my PS3.


      The firmware on the router is V2.02.44, can anyone confirm this is the latest? While on the phone to sky support I asked about upgrading the firmware, and was told to hold down the reset button for 15 seconds and the firmware would be upgraded automatically. Is this really the case? I should have checked the version before I did it but the red mist had descended by then.


      All suggestions gratefully received and sorry for the long OP.


      p.s I'm posting this via Ethernet cable as the wifi has been down for the last hour!

      Could I suggest that you manually set the DNS server on your laptop?

      This has helped me in the past with constant WiFi issues. Any public DNS server will be fine.

      I would not suggest that you set a fixed IP address on the Laptop as this could cause issues when you go elsewhere and use a different router.

      Public DNS Server List (Updated January 2012)

      Change TCP/IP settings

      Previous ADSL2+ Speed 19999 kbps 1153 kbps, Line Attenuation 17.5 db 6.9 db, Noise Margin 7.5 dB 8.7 dB

      Absolutely, suggest away.

      Thats not anything I would have considered to be honest, why do you think the automatic DNS settings would affect the wireless signal between laptop and router?

      No harm in setting some static servers anyway, Ill set them on my wireless card and unplug my cable and see what happens..

      Using inSSIDer, does the WiFi signal keep dropping from the router?

      If this is the case, then I would suggest that the WiFi is either being interfered with by something locally or the router is faulty.

      Use inSSIDer to find the clearest WiFi channel for where you are and change the router accordingly. Try to stick to the following channels as the others will overlap: 1, 6, 11 & 13.

      Other things can interfere with the signal, such as microwave ovens, TVs, AV senders, so check to that your router is not close to them.

      Re: Intermittent Wireless Drop-out

      Thanks Scubbie, thats a neat little program. Its showing my signal at a strength of between -13 and -17 no matter what channel I use, whereas I have about 10 other wifi networks within range (block of flats) all transmitting a signal strength between -70 and -90.

      I think this proves that the wireless gadget in my router has a fault.

      I guess now I have to wait for my microfilter from Sky before I can escalate the call, unless anyone has any suggestions in that respect??

      I was 99% sure my problem wasnt down to that but because the guy on the phones screen said "replace microfilter" we couldn't take the call any further.

      Re: Intermittent Wireless Drop-out

      You could call up and politely show that the WiFi signal is dropping, if this is the case.

      Another thing to try would be to ask a friend if you could borrow their Sky router. You could also try yours in their home. Please DO swap the PSUs at the same time as a PSU can go faulty. With this in mind, if the fault stays with your router in their home, swap the PSU over temporarily to see if this resolves things.

      As for the microfilter - personally I would no think that this is even close to the cause. I would collect as much evidence to prove/disprove a faulty router in the mean time.

      No.
      As the figures are negative it shows your signal is at least 53 dB STONGER than the next weakest signal.

      Ah I see, which would make sense considering I'm meters away from mine and much further from the rest..

      So if my signal is ok, is there anything I could check to see why:

      - when my wlan is available I can't connect any device to it

      - why its sometimes unavailable

      - why when I am connected to the router wirelessly I get no internet connectivity, but I do get an internet connection if I plug in with a cable

      Do you agree it sounds like a hardware fault somewhere within the router?

      Have briefly skimmed over the thread, so apologies if this has been done/asked. Have you tried changing any settings on the router?
