Another "connection drops" thread

i browsed around the first page and it seems a lot of people have been experianceing this. Now, i was away at college the past year so i was used to high speeds i got, but i should NOT have to wait 10 minutes to watch a 3 minute youtube video. no one fiddles with anything (since the rents are too old to understand technology, haha). but this isnt about the slow speeds
After i came back from college, i was eager to set up my desktop and download music, maybe play some games and what not. however, it seems that whenever i play any of my games or download a "large" file the connection drops. Its been 3 days and i cant download this 400 megabyte file because when the connection drops i have to restart the download. You guessed it, the "data" and "DSL" lights are on but the Internet light shuts off.
Verizon seemed to be getting alot of these, so heres my specs
Windows vista ultimate 64 bit

Margin (dB) - Signal to noise margin. 6 is pretty bad possibly unusable at times, 20 is very good. You normally want 12dB or better IIRC from back in my DSL days. The higher the number, the better to a point.
Line Attenuation - Measure the amount the signal has degraded. Below 20dB is excellent, above 50 is poor, fill in the dots for anything in between.
#1 Did you try connecting your modem directly to the NID?
Points to: http://www.dslreports.com/faq/1317
#2 If not, please do and retest those margins and Line Attenuation.

Internet Connection Drop Outs when remote administ...

I did not want to trouble anyone here if I thought it unnecessary but now I feel that I do need some assistance so this warrants opening a new thread.
BT Infinity Option 2 customer with BT HH 4 and its separate modem - not hacked so cannot read any useful information or login to see what is going on and both BT and the manufacturer long ago removed the open source code of the modem.
I am quite confident now that these disconnections happen when a remote server/attacker attempts to gain access to my network. These can be from China, Iran and other places too. Sometimes Ministry of Defence? I don't know why I get these connection attempts and most of the time I see BT HH 4 does block these so why I get disconnected I have no idea?
I made a post in an old thread before opening this thread and said it was due to firmware upgrade but I misread the date! It was not updated since the 8th of May I think. These disconnections have been happening only this past 4-7 days with the most 4 days with intensity greater than the 3 before. I am not 100% certain it is caused by the remote administration that is blocked.
What happens when this takes place is the BT servers are then unreachable sometimes and I cannot regain a connection for up to 3 hours at a time, usually it is 5-10 mins max though. Without looking at my event log, any ideas?
I want to get different gear now and never wanted to use BT equipment anyway because I want greater control and options to configure. I would like to go with DD-WRT or OpenWRT Router with Integrated VDSL v2 modem. Anyone here that may suggest one that supports either of these open firmwares? Not so much the concern to prevent any security holes or backdoors but just as much if not more for versatility and configuration and just having control over my network. being able to do upgrades when I want and not when my ISP decides needs doing. And before you say BT do not have backdoors then why would they admit they can remote login to devices and storage contents with their pwerline adapters even. I remember reading a news article quoting BT as admiting this. Anyway, that is not my main concern here, as much as privacy and security is not a crime it is rather rare online. First I need to get to the root cause of this.
BT HH 4 is not reporting any DDOS attacks and even if it were I would not expect to experience any disconnection. I used to get tons of floods from DDOS attacks years ago when using Netgear routers and never exeprienced any downtime, but that was with another ISP. I don't detect any malware or anything like that and rarely download anything on this machine, I know web browsing can infect a system but I don't think that is it.
I want to go back to how I used to do things. Any help with this is appreciated. I will need to get my router login details because I was never given those when I singed up with BT Infinity Option 2. I don't even know what my BT email is but do believe there is a way to recover that under my account. **In the past we have had intermittent connection drops and loss of sync but this is not the same right now.
Edit:
** Just to clarify that was before we upgraded to BT Infinity Opt 2. This is the first time any probs with this service since upgrade and that must be about 6 months or more now.

When running BT HH diagnostic it printed out that the username for login had changed and needed resetting or for me to enter my own in that I was NOT given! Anyway, when going to select manual reset it had not changed from default at all so I think this is just some default BT diagnostic that is false. I realise that other BT customers are affected by this with the BT HH5 but mine is HH4...my posting probably isn't as clear right now as I have not slept as much past few nights trying to figure this out. This is happening at different times of the day but more often during early hours.
So I am getting these WGET TLS error(s)
How do I enter in log excerpt from BT HH? Forums says my post exceeds 20K chars...

Home hub 3, broadband connection dropping

Hi, just a few days ago I recived my new home hub 3. The reason I wanted the upgrade from the hub 1 is because the broadband connection would drop and also the old hub would reset it self constantly.
The new hub is much better in terms of not resetting itself, if i try and watch something on 4od etc, youtube, it feels like any stress and the braodband connection drops, I had this on the old hub but it feels like its happening more now.
So much so I decided to make a paint version of my wiring so someone can maybe help me out.
http://i144.photobucket.com/albums/r173/guysy1110/routerproblem.png
Sorry the paint image came out much smaller than I wanted.
The main phone line is dowstairs in the lounge, its split into 2 using a 2 way splitter, one goes to the main phone which has a microfilter attached, the other plug leads up to the spare room and there a phone box (sorry not sure what its called) is in place, this box was split into another one because a long time ago there was a router that lived in the spare room (the split box is unused). Probably confusing people now, but the main box upstairs in the spare room is extended into my room and then a microfilter is used and then goes into the hub.
The extension cable is FAR too long, possibly 10m of cable wound up and tucked behind the drawers. Could this be a problem? I guess so.
So my main questions are, if both the router and main phone have new microfilters on, what other causes could keep my router dropping the broadband connection? the extension into my room is FAR too long possibly 10m which is wound up behind my drawers, first off im going to get a shorter cable.
Also the microfilter is closest to the hub, would it be better at the first source downstairs, or even in the spare room?
Any suggestions would be great. thanks.

Im reviving this thread, so far from the phone box upstairs Ive shortened the cable, It still goes into my room but now instead of having a ridiculous 15m amount of calbing unused Its a straight 3m from the other room to mine.
This has slightly improoved things.
However the hub still suffers and drops the broadband connection when under "stress" when the phone rings it sometimes drops, and when downloading files it drops halfway through if the file is large which is a massive pain.
On the downstairs master socket I removed the facia and did a quiet line test on the inside socket, there was no noise. I used a corded phone. I wasnt sure if it mattered but I tested all other sockets using this method and none had any noise.
I phoned BT and was advised to take the hub closest to the master socket, but if i do this I have no wireless card in my PC so cannot connect, The obvious option is to get a wireless card but that will cost money. As will buying the power lines.
Any suggestions? I guess plugging the hub in downstairs and trying to connect to something is the best option.
Any advice please?

Yet another grey folder thread, help!

Sorry for yet another grey folder thread, but here goes:
Today, earlier, installed Firefox update, along with some addon updates for that program. Quit Firefox and attempt to relaunch, relaunch fails. Reset computer, thinking that will do the trick, I now have grey folder with question mark.
Resolve attempts: reset pram = fail; apple care cd = will not launch/fail; disk utility from original install disks = fail; cannot get repair of disk or permissions to work, continually get error about "failing on exit"; safe mode launch = fail
So, I've done everything, and I've come to conclusion that I am f***, and my HDD is fried (but I hope I am wrong).
So, dear gurus, my question(s)
A) Is my HDD salvageable at all? is there some trick to getting the AppleCare cd to work? Anything?!?!
if not, then B) How can I recover my documents/music/pictures? Long story short, there are several things on there that never had a chance to make my back up schedule, and I desperately want to keep them. Any way to make/copy a disk image to save the docs/imgs, or Firewire them to an external hdd? Do I need to consider a professional HDD rescue?

Looks like a mechanical failure, and Apple won't cover the replacement due to a drop it sustained a year or two ago (the power cable was in, and it fell on the connection point, denting that in, Apple states there is a critical board their and that it would be $950 Tier 3 repair which I can't afford). So I'm going to try a Firewire Migration and a few other things and see if that works. If not, oh well. Thanks everyone for the ideas!

Wifi Connection drops but still have all bars. Please Apple, respond us

I have a macbook pro 13''(purchased 1 month), a white macbook (bought in 2007) and a dell vostro 1310 (with windows 7) using the same router WRT54G2 Linksys or D-link 524
Only on my macbook pro 13''my connection drops without explanation and without a certain period (15 minutes, 1 hour, 2 hours).
I'm with latest updates (both macbook as a router), already formatted and applied the 10.6.4 combo. I have already put ip manually turned off DHCP, DNS already placed manually, I swapped the channel router. Everything recommended in official forums, but nothing helped.
What makes me saddest is that Apple does not respond. Even with so many threads about this problem.

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) 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. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Internet Connection drops when incoming telephone ...

On 14th December 2011 during a period of very high winds and heavy rain an incoming telephone call caused the internet connection to drop and it eventually restored itself after about 2 hours. When I answer a call the internet connection drops after about 30 seconds and then reconnects after about a further 40 seconds. All incoming local calls cause the internet connection to drop. As far as I can tell incoming calls from other exchanges seem to be OK. Incoming calls from mobile phones sometimes cause the internet connection to drop. The line is unaffected by outgoing telephone calls. I have a BT HomeHub 2B plugged into an upstairs telephone socket and connected by ethernet to my PC. I have another telephone socket downstairs, each socket is fitted with a filter. I have have tried every combination of my two standard telephones and 4 filters in each socket and every local call causes the internet connection to drop and reconnect. I think it very unlikely that both phones and 4 filters have become faulty at the exactly the same time. I have connected the Home Hub and telephone with a filter to the test socket and asked a friend on the local exchange to call me and the internet connection dropped and reconnected as before. Since moving to this house 2 years ago I have had four previous interruptions to the broadband service all of which were caused by problems probably at the exchange. The last one took 8 days to correct after countless calls to the "Help Line". Their fall back position is always to assume that there is no problem with the BT line. So I am not even going to try to explain this over the telephone. This is the information on the BT Home Hub Event Log, it is typical for every occurrence of the problem. Dec 26 11:42:42 2011 ERR 2011-12-26T11:42:42Z cwmp: mt_cwmp: session error: Could not resolve host Dec 26 11:43:19 2011 (1035438.010000) RTNL: Received ERROR reply 'No such process' for message type 0x19 Is this a problem with the Homehub, the line, or at the exchange?

not sure I read your post correctly but are you saying if someone from another exchange phones then the broadband is ok and it only drops if someone from your own exchange phones?
if the possible sollution from chris6273 does not work, and you have already tried the test socket then I would contact the mods for assistance http://bt.custhelp.com/app/contact_email/c/4951

BT Infinity Connection Dropping but BT refuse to a...

Hi,
So in September we got BT Infinity. It was a hassle and handled terribly by BT customer service but we eventually got it. It's been working fine for around five months but within the last few weeks we have been having connection issues.
Over Easter I have spent over 10 hours on the phone to BT via my landline and mobile trying to get a solution, but all I have got is a repeated denial of my problems.
On the 27th March I called BT to report that our connection had been repeatedly dropping over the past few weeks and a fault was opened. I was told I would be updated but no-one called back despite promises they would do.
I called BT on the 28th March to follow up my issues but was met with an advisor who lacked knowledge in the issue and simply told me to continue monitoring my connection.
I called BT on the 3rd April as there had been no improvement in my connection, which is dropping multiple times per day, and on this day 7 times. After going through the same repetitive questioning session about how I connect to the internet, a deep line test was run, and it was decisively concluded that there was a fault with the line within BT's retail servers. I was told this would be followed up and promised a call back on the 4th April.
After I had not received a call back on the 4th April within the time allocated to me, I called BT where I was met with an awfully rude woman who had no interest in helping me and went on to suggest what I was saying was an outright lie and she categorically stated there had been no call back booked despite me having the text in front of me which confirmed it.
After being told to 'continue monitoring my line', a slightly repetitive phrase favoured by BT Customer Service, I called back as instructed on the 8th April. Again, I went through a repetitive process before finally making some sort of progress and being sent a new home hub.
My new home hub arrived on the 11th April and made no difference to my problem. I therefore called BT and spoke to an advisor who told me he could only assume the Home Hub was sent in error, as he was absolutely adamant it would make absolutely no difference to my situation. I was told to 'continue monitoring my connection' over the next few days but before he ended the call I asked him a number of questions, none of which were adequately answered.
Why is our connection dropping? Rather than giving me an explanation as to why it is dropping, he told me that we are lucky it only drops a few times a day! He said 'everyone in the world suffers from a connection which drops multiple times per day' and that 'there is absolutely nothing we can do because there is no problem'. He told me about rate-adaptive lines, which according to him 'are used by every household in the world' and that these lines 'inevitably drop out up to five times a day, which is normal and acceptable'.
So how many times can it drop before it's considered a fault? The basic answer I received is that there is no limit! It doesn't matter how many times it drops, it absolutely normal! Only if it drops '20-30+ times per day' is it considered a problem worth solving to BT.
Why do you never call back (in particular, why did no-one call back on the 4th April, and why did an advisor accuse me of lying about the call back)? They said that when the issue is escalated from Level 1 to Level 2, it is impossible to see any contact between the customer and Level 1, so when the call back wasn't arranged as it should've been, there was no way BT could've known. He apologised for this and the way I was treated by his colleague.
Why was a fault reported on the 3rd April? Why have I not been updated since? Simple answer from BT. There probably was no fault, that was probably also incorrectly opened. Note the key word probably. The advisor I talked to said he had no idea what happened in any of my previous calls and that there was no way he could find out why the fault was opened, or listen to the call (despite all calls being recorded). He said it was impossible for Level 2 to hear the content of any calls made with Level 1 and that it was 'impossible for an advisor to take notes for a call lasting more than half an hour'.
I recieved a call back today on my mobile where I was told just to continue monitoring the fault. However I was also told, again, quite categorically, that there is nothing wrong and that he would happily send an engineer in three days but that 'he would be able to do absolutely nothing. It would be a waste of time'. The advisor also refused to give any details on how much this would cost and was desperate to end the call saying 'goodbye' despite me being mid sentence multiple times.
I have now been told to 'continue monitoring my connection' and await another call back on Friday, by which point I will have wasted many more hours on the phone to BT.
Your customer service is disgusting. Your lack of compassion and understanding is disgusting. The way you totally mislead customers is disgusting.
And now for my top BT Operator quotes (or near quotes, as obviously no-one has any idea what was said in these calls, not even BT!):
"If your temperature raised to 100 degrees celcius but then went back to normal, there would be no problem, it's the same with broadband"
"Everyone in the world has a rate-adaptive line and everyone in the world should expect their line to drop"
"If your line only drops 5 or 6 times a day there is no problem, you obviously should've known this before you signed up for Infinity"
"There definitely is a fault.... there definitely isn't a fault" - the trademark conclusiveness of BT
"We can limit the speed on the phone line, but it would have to be to 1mb" - this is despite absolutely contradictory help published by BT
But despite these humorous moments, I have wasted a huge amount of time on the phone to BT.
I have one simple demand. Stop the broadband from dropping multiple times per day. If you cannot do this, let us leave, as you are not meeting your contractual obligations and therefore we shouldn't have to either.
And please... don't apologise for your colleague not calling back in the first minute of the phone call and then not call back.

Hi Bryan,
Like yourself and many, many other people who come to these forums - I have been experiencing the same problems. Constant disconnections, and recently, speed dropping to 4Mb in the Evenings (I'm supposed to be getting 74Mb).
It's ridiculous with how many people are experiencing these problems and BT are blatently ignoring it. To add insult to injury, this was posted in February. A statement from BT basically saying "Well you're all gonna be having problems, but it's on you."
Don't fret though, the moderators, and other people from the community can be fantastic help.
Purchasing an Openreach modem, suggested by ray_dorset, I'll still be awaiting for the Huawei 612, V3b modem to arrive and hoping this will fix the drops in speed. I currently have an ECI modem fitted in, which has stopped the disconnects, but have not stopped the speed drops.
For anyone reading this who is unfamiliar with modems as I was:
As far as I know, there's currently two types of Openreach Modems. Every exchange is built with a certain "chipset" which will work best with these modems (explaining in simplistic terms and I could be very wrong, so I am happy to be corrected.)
The Two Openreach Modems:
Huawei 614
ECI
From the advice I have been given by the moderators, if you're new to BT Infinity, then your exchange may have only recently been built, which is then most likely to have a chipset which will work better with Huawei modems. I'm about to find out this by next week.
If, in some horrible scenario it doesn't work and the speed is still constantly dropping, then you may need to fork out and purchase a new router (BUT KEEP THE MODEM). Many people have said their internet has been fixed by doing this.
One of the things I did find pretty hillarious however, is that I did call up BT the other night due to having terrible connections. He told me to take out my modem and just use the home hub 5. He then kept telling me to change a few settings on the HH5 and run a speedtest. Every, single, time we changed something - the speed would get lower and lower, followed by an "Uhhh, monitor your speed over the course of this week and then we'll call you back."
I'm sorry, but BT customer service have no idea how to fix this, so don't waste your time ringing them. I genuinely feel bad for them too, they have to put up with our **bleep** while the engineers at BT who work on the firmware for the HH5 can't be arsed to try and fix it any further.
Seriously, mate - just try the steps above, come to the forums if you need help because you're more than likely to get a better answer. I know it sucks not being able to call up BT because they're just going to give you a bunch of BS, but if everyone who had a complaint on this forum worked for BT tech support, maybe there'd be more satisfied customers.

Connection drops with arch64 and atheros wireless

Hi, I've just installed arch64 on my desktop. I have a dlink dwa-556 wireless adapter, with atheros chipset. The card is seen correctly and has been configured. I started a kdemod install with pacman, went on for about an hour, and then it hung, the wireless connection dropped... I tried to start it up again, but only a reboot could help... now I started pacman again and after some minutes bang! connection dropped again...
this is what iwconfig says
wlan0 IEEE 802.11bgn ESSID:CUT
Mode:Managed Frequency:2.432 GHz Access Point: Not Associated
Tx-Power27dBm
[cut]
Link Quality:0 Signal level:0 Noise level:0
[rest is all 0]
iwlist says my router has a quality of 30-40/100 and a signal level of around -76dBm
any help?

I think I may be experiencing something similar. I'm also running Arch64 and have the exact same adapter (DWA-556) and every once in a while my wireless connection drops. It only happens once every few days or so, but whenever it happens on my system it seems to cause anything Xorg-related (mouse, keyboard, video) to respond slowly. If I move the mouse around it doesn't move smoothly - it kind of jerks and jumps around.
Whenever the connection drops like this, I see the something like the following in /var/log/messages.log:
Feb 16 17:07:26 blacktower dhcpcd[19326]: ath0: carrier lost
The first couple of times this happened to me, I had to reboot to get the connection going again. I did find another way to get the connection working, though. What I did was unload the modules related to the wireless adapter, reload them, and then reconnect to the network. I wrote a quick shell script to do this for me, which looks like this:
#!/bin/sh
sudo rmmod ath_pci ath_rate_sample ath_hal
sudo modprobe ath_pci
sudo modprobe ath_hal
sudo netcfg -d home
sudo netcfg home
I'm using the madwifi driver right now and as you can see, I use netcfg to connect to my wireless network here. I've tried the ath5k driver but I seem to have the same issue with that. I haven't really found a solution to this yet, but the workaround of removing the modules, reloading them, and then reconnecting has worked well enough so far. If I dig up anything else helpful on this, I'll be glad to post it here.

Constant Connection Drops

I'm Panther (10.3.9), RCN cable, no wireless, no router.
My connection drops 5-10-15 times a day. Hitting "renew DHCP lease" brings it back. I work at home and am often up/downloading large graphics files, and this is destroying my productivity.
I tried calling the RCN tech support line. Nothing useful. They said my connection is fine, and besides don't have anyone on the floor who knows anything about macs. I called Apple tech support. Baffled. They said it might be my ethernet card, but were doubtful.
As a last resort, I brought my computer to a friend's house and hooked it up to her DSL line with the same ethernet cable. It stayed connected for 10 hours straight. I brought it back to my apartment, and the connection dropped. A tech came by and replaced both the modem and the cable today. Connection STILL DROPS. RCN thinks I'm hallucinating or something and continually denies there may be an issue on their end.
The service worked perfectly for 2.5 months, and then went splat! I didn't do anything at my end. One day it worked, next it didn't.
Suggestions? I would get a new ISP, but RCN is the only one that services my building.

This is exactly the problem that I'm having with my WRT54GS v6.
Usually it will stay connected to the Internet for days, but once in a while (like yesterday) it constantly loses connection.
My first indication of trouble is a web page not loading or a game becoming disconnected. Browsing to 192.168.1.1 usually works, where I'll see that the Internet has become disconnected. However, sometimes the router doesn't even respond at all, and I'll have to wait and refresh the page a few seconds later. Clicking the "Connect" button usually works to reconnect to the Internet, but it doesn't always work right away and then I have to try several times.
When this happens, quite often I'll get reconnected for less than a minute before it disconnects again. I have just time enough to verify that web pages are loading normally, online games can be accessed, etc ... and then its gone again. Suffice it to say that this is extremely frustrating.
I've seen alternate (lower) MTU values suggested here and in other threads. I'll give that a try for a few weeks and see how things shake out. I think the default was 1500 or 1492 or some such. I'm going to lower mine to 1450, as suggested here, or possibly as low as 1300, as I've seen elsewhere.
Are there any other useful troubleshooting tips that you would recommend for this type of issue?
Thanks for your help,
- Adam.
Edit: I should mention that yesterday I finally removed the router from the network and connected my computer directly to my modem. The Internet connection has been working without any trouble this way. So it would seem to not be a problem with my ISP or modem, and rather with the router, as I had suspected.Message Edited by Kaspre on 08-28-2006 09:11 AM

Cisco VPN connection drops on airport extreme on OS X 10.6.7

I recently bought Airport Extreme and I must say the wifi coverage and strength is amazing compared to the DLink or Belkin routers that I tried. THe whole thing setup like in 2 minutes. Love it.
Now the problem. I use CISCO VPN provided by work a lot as I work from home frequently. I have found that the VPN connection drops like in 2-5 minutes of connecting. I looked through the several threads and apple response " to use NAT-T in CISCO VPN preferences". Only thing is that I did not see any NAT setting options in preferences and also I am unable to edit anything in the CISCO VPN pref (probably things locked out by our IT who provided the vpn software).
I also tried someone's suggestion that I switch to manual radio channels in the airport utility config - but that didn't work either.
Any suggestions?
I am on OS X 10.6.7 and CISCO VPN CLIENT 4.9.0.1.0180
URGENT HELP NEEDED

airport is off how can i turn it on?
Click on the AirPort icon in the OS X menu bar. Select "Turn Wi-Fi On" or "Turn AirPort On" as appropriate.
how can i reinstall mac os x 10.6.7?
I would suggest that you start with the Snow Leopard installation disk. You can then update to 10.6.7 from Software Update.

Hi Niko,
I already disable IPv6 and IPv4 checksum offloading, also check the MTU on each HT but still no luck.
I found the following error on the Netmon:
i already tls on receive connector, enable anonymous authentication, still no luck.
any idea?
thanks.

Connection drops on a daily basis / Varying (low) ...

People probably know the drill by now, everything is fine then suddenly they go through a period where they receive barely a 10th of their paid connection speed, with their connection dropping completely at least once per day.
This all started happening when BT somehow increased our connection speed from 8Mbps to 21Mbps and also increased our upload from about 250kbps to 1Mbps which happened a couple months ago now. This was great! Everything was working fine, no drops in the connection or speed and it seemed like they had given us a nice boost for free.
That is, until things started going wrong about a month later when our connection would frequently drop, the connection speed would often fall to below 1Mbps and this is still happening.
With regards to solving this problem myself, I don't see how anything could be interfering with the setup I currently have, as nothing has changed within the house itself. Before I ring up an Indian/ Chinese/ Scottish/ Martian call center, I'd like to try and get some feedback from the users on this forum.
I'm going to buy some new ADSL filters just to see if the ones I'm currently using are packing up (they're cheap so that is no problem if nothing changes).
I have run quite a few speedtests using the recommended btspeedtester and have had varying results, all of which barely, if at all, meeting the acceptable range of speed for my line. Here is my most recent test:
Download speedachieved during the test was - 4563 Kbps
For your connection, the acceptable range of speeds is 4000-21000 Kbps.
IP Profile for your line is - 11000 Kbps

Thanks again for the reply.
I connected to the test socket and saw a difference straight away when my internet reconnected. I ran another btspeedtest and here are the results:

I don't suppose it's possible to simply leave things as they are connected to the test socket?

Connection Drops on a WRT350N

Anyone experiencing connection drops on a WRT350N. I set it to N only and I get drops. I set to G only and I have no drops. Using Dell E1505 with XP Pro SP2 and a Dell 1500 draft N wirless nic.
Linksys WRT350N v1 (Firmware Version 1.03.2)
Linksys WRT54G v3.1 (DD-WRT v23 SP2 09/15/06 std)
Linksys WRT54G v2 (DD-WRT v23 SP2 09/15/06 std)

I am still getting these same issues (for a couple months now). I had to lock my router down to G only just so I wouldn't get those drops. My issue is (besides the fact that it should work anyway) is that I have a G bridge so I cannot lock it to wide band.
My other problem is that it even drops my and my wife when wireless and wired still. She has problems connecting to her VPN unless we reboot everything (router, modem) and try again...and then it usually works for at least another day.
any ideas? I did receive the beta firmware (which wasn't said to even fix any of my current issues) but it did not help at all.

Wireless connection drops out for no reason

I have a macbook with 10.4.11 update. I had my macbook since october last year and had no problems. About two months ago now i have this problem were my wireless connection drops for no reason, my modem/router shows everything is working normal with its lights on the front panel.
My setup is, motorola sbg900 on a cable 80000mbps wireless network, firewall off on my modem, firewall on on my mac (its always been on), Playstation 3(wireless), PC(wireless, but is switched off), another pc which is wireless and also off, nintendo wii off as well, and a baby monitor.
I have a feeling its nothing to do with my setup(except for maybe port forwarding) but am wondering if it is an update issue bug that needs to be fixed(thats what im hoping).
One other thing, when my connection drops in the menu bar and i select it to see which networks are availale, my network motorola8566 is not visible, another 'motorola9522' and 'wireless' network is?My prefered networks dont list any of these in system preferences. Then all of a sudden those other networks dissapear, my network is reshown and i can select it no propblems. What gives? Any help would be great, thanx in advandce

I have the same issue with my wireless connection being dropped. I have the most recent version of leopard 10.5.2 . The other macbook in this household also has 10.5.2 and has no problems with dropped connections. I tried resetting the pram which helped at first until I used my macbook on the battery alone the problem started to reoccur. Help?!?

Wireless connection drops after time. Please assist.

Hi
My problem is that my wireless connection drops every 5-15 minutes.
I don't know all the relevant info to give. If there's something I can post that will help let me know and I'll reply.
I've used netcfg to configure my network. I have a Canyon CN-WF511 wireless card.
I load the following 3 modules in my rc.conf; rt2500pci rt2x00lib rt2x00pci. I think those are the only ones pertaining to my network card.
When it drops I just netcfg -a then netcfg default (profile name) and it works for another few minutes.
Below is my network profile.
CONNECTION="wireless"
INTERFACE=wlan0
#IP="dhcp"
#DHCP_TIMEOUT=20
IP="static"
IFOPTS="192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
GATEWAY=192.168.0.1
#DOMAIN=localdomain
#DNS1=192.168.0.1
ESSID=default
SECURITY=none
SCAN="YES"
TIMEOUT=15

The easiest solution might be to setup NetCfg somehow with your wifi card and access point. Have you tried that? Can you find your card's chipset on the wiki?(chances are that your particular chipset will need a firmware put into /lib/firmware. Again that's found on the wiki on the NetCfg or Wifi page, I forget which sorry.) Those are two places where I'd look for good information.
By the way, your rc.conf is way out of date. You should look at updating it by using the recent rc.conf.pacnew file that you'll find in the /etc directory.
