Internet keeps going on & off (intermittant prob)

Featured Replies

I am with virgin for my internet and since yesterday i keep losing connection so i phoned them and was told to connect my router directly into the main socket and unplug the extentions, it did the same adsl light just blinking.

So then i decided to install my old speedtouch moden and try this constant adsl light with no blinking so i took the router back to the shop and they tested it as its only 2 months old and they said it was working fine :rotz: but when i get it home it connects then disconnects but when i plug the old speedtouch modem in i get a constant adsl signal.

Dont know what else could go wrong or to check - i have reset the router to all default settings and its still the same.

I cant understand that they say it worked in the shop as i am convinced its the wireless router, the only other thing thats different is that the speedtouch usb modem connects to usb (sorry i know that sounds silly) and the wireless router connects to my ethernet port.

I was thinking could it be a faulty ethernet cable going from the PC to the router and as such have run the diagnostics on the router but everything comes back clear.

I am stuck as if it carries on i may have to ask virgin to escalate it with BT to check my line etc, our eldest is in his final year at school so i bet he will come home with loads of homework to do and need to use the net.

If the ethernet cable is suspect whats the best way to test this (i have heard you can plug both ends into the router) but not sure where.

Thanks

Faulty filter?

Are your phone calls noisy?

If the DSL light is flashing then the problem is there, not with an ethernet connection.

Did you use the same DSL filter with the speedtouch as the router? How about the cable from the router to the filter?

Check the DSL settings in your router.

If the DSL light is flashing, it could be the router failing to authenticate a connection with your 'phone exchange. Have you checked and double-checked your username and password on the router?

thanks for the help, i have checked my user names and password in the router and this is ok, I also tried this with 2 different filters and still the same.

The adsl light is flashing quite fast (a bit like the light for the ethernet ports when another machine is getting data)

I thought about the extension cable from the filter to the router but dismissed this as i used the same cable to use the speed touch usb modem.

I have however (only a few times though) noticed that my router doesnt show my username and password for my internet provider.

Phone calls for voice etc are fine very clear without any interference.

Its strange i am typing this using the wireless connection and it hasnt gone off for an hour or so, but tomorrow it will be a nightmare.

thanks everyone - just hope its not my router not remembering to authenticate user name and passwords as its only 2 months old and the shop said it was fine but this was only a quick test.

I was wondering how you were online now! What router is it you're using? And have you got it into the BT Master socket?

Steve

Have you got DEC phones ie with message retrivel , sometimes i find the same prob , if there are messages waiting to be heard or erased , also try it direct into the telephone socket with no phone connected , if there is a difference it may be the digital phones .

Thanks The router i am using is a TP-LINK Model No: W8920g I have tried it direct to the BT Master socket with everything unplugged and get the same the Speedtouch mosem seems to be ok.

This may be a long shot but I seem to get more of an issue when my sons upstairs PC is on and when its off its not as bad (although still disconnecting).

Should the adsl light be flashing very fast while a PC is obtaining data from the net, never really payed that much attention to it until now.

Thanks again.

could be an outside line problem. We get this alot , especilly when it rains (like always!). Phone seems unaffected but broadband goes off. BT engineer told us "off the record" that it was due to poor quality of overhead lines.

Funny you mention that as yesterday it was really bad and it was raining but today is just windy with no rain and its been ok (so far)

whats throwing me is that the old usb speedtouch modem seems to be ok for adsl signal when the wireless router goes off.

Hope its not the line outside as it seems to take BT ages to sort it like last year i was without internet for 7 weeks because of a faulty surge protector on the line somewhere.

Thats because your speedtouch isnt a permanent connection to the internet, Routers are more sensitive to the amount of noise on a line than your speedtouch.

Different routers react differently to poor line conditions, some are more tolerant than others, as I have not heard of the one you have I suggest it maybe from the cheaper end of the market. Investing in a more expensive one from a recognised brand (3com, linksys, belkin) might help as the adsl might have more gain.

Thanks I have now bought a Linksys router model WAG54G2 and had the same problem however i have now connected it to the main wall socket and so far its been fine, I do have a dsl extension lead running from the first filter at the main socket this is 10 metres and the excess cable rolled up.

I have been told it is bad to have such a long cable from the main socket to the router and am thinking if this extension cable has been damaged (somehow)

Then again its not raining today and not as windy so maybe thats whats throwing me, these problems have you ripping the house to bits lol.

So far so good - just wish it would rain now to make sure as if it goes off when it rains it looks like i will have to get BT out to it.

Is the Linksys router a better router than the TP Link one i was using as i paid 40 quid for it.

Thanks guys

Forgot to mention what is the best security option for the linksys router as there are loads of options such as wep, wpa, wpa2 wpa2 psk then there is wpa2 personal, wpa2 corporate

not sure whats best to chose at the moment its on wpa 2 personal

WPA2 PSK I set mine to.

I'm a bit confused by the info above. You now have a new Linksys router (sounds more promising) and it's connected to the master BT socket (good idea).

But are you saying the Linksys is connected to the BT master socket by a 10m telephone cable? If so, can I ask why? Why not connect the Linksys to the phone socket using the shorter length of telephone cable included in the box?

You're right; it's best to have the router connected to the phone socket using the shortest length of cable possible.

Steve

WPA2 PSK I set mine to.

And if your router supports it, use WPA2 PSK with the encryption set to "AES" rather than the default "TKIP". AES offers better security, TKIP is a rework of WEP which has been cracked.

Don't know if this applies to Virgin Broadband but we had the same problem with Orange. It kept dropping off, the problem was solved by changing the Channel on the box and it know works a treat............May not work for you but It work's for us..................:)

If you plug the filter with the short router lead into the front off the master socket all your extn. cabling is still connected to the line and may still be interferring with the broadband signal.

You should be plugging the filter with the short router lead into the test socket behind the master socket frontplate to prove whether the cut off fault is inside or outside your house. You should also be using the ethernet lead not the wireless connection to do this test and rule out any wireless connection problems.

A randomly flashing DSL light is caused by data flowing between the router and your broadband supplier's server and is not necessarily a dropping connection.

If you do not have the user name/password listed in your router you would not be able to get any internet pages at all, as the router will not be logged onto your broadband supplier.

Cheers Steve, The reason i had the 10m dsl line extension cable was when we moved here we had the PC in the front room (quite far from the main socket) the PC is now moved into the other room nearer to the socket.

I have now bought 5m belkin ethernet cable and the router plugs into the main BT socket and now connects to the main PC using the 5m ethernet cable.

I have also ripped out the old ethernet cable going to the pc in the attic bedroom and put a brand new patch cable in, I had to do this because there wasnt enough of the old patch cable to run where the router is now situated which is near the BT master socket.

Forgot to mention as a result of this i lost my phone line and havent been able to go on line whatsoever since last monday. Then on wednesday my phone went dead couldnt even make calls.

So we had to get BT out who said that there was water getting in the main BT socket from outside as there was no drip loop on the cable entering the wall and no weather seal so the water was just running down and into the wires (its always water)

When the line was first installed years ago they left a big loop at the top of the house as a resource for the need to ever require more spare cable and this enabled them to pull a bit of this loop down - feed it back into the house then re-wire the socket.

So far so good (but its not rained since) god i am so paranoid now about this, they tested the line and said it was now clear.

Then the engineer said he will go into the green box at the end of the road and disconnect the line for a few mins then re connect it otherwise i would be charged £150 as it was classed as "inside the property" but it was their line cable not mine, anyway it was good of him to do that and also it gave him chance to check the connections at the green box aswell.

What a week its been i have been ripping the house to bits, tearing out old telephone extensions, and bought a new router.

So far so good....

Finally is the Lynksys router better than the TP-Link one I had.

Good news it's been cured then.

Water should not have got into the main socket/NTE . Its standard procedure for the installer to form a drip loop and seal the hole with silicone so you could not have been charged for the visit anyway. You probably have noticed that you still have slow download speeds, this will automatically re-adjust upwards over the following week, or you can ask your broadband supplier to adjust the "IP Profile" manually to raise speeds sooner.

Point to note- It doesn't matter how long the ethernet cable is, up to 75metres is usually ok, but extending the line cord from the filter to the router does cause problems with airbourne noise being induced into the cable.

So the 10m of line cord going from filter to router wouldnt of helped, Least its been re-newed now and the ethernet patch cable is 20m to the attic room.

Why does it take a while for the speed of the broadband to get back upto speed.

Just glad to be back on line - I have missed my Briskoda fix :D

Finally is the Lynksys router better than the TP-Link one I had.

Yes of course it is. I would stick with the linksys one, ours is still running after several years without any problems.
