Sonnet USB PCIe very slow speeds

I have just noticed that hard drives connected to my Sonnet Allegro Express PCIe in slot 2 operate at about half the speed compared to one of the built in USB ports.
I know slot 2 is single lane, but I thought this was OK for USB. Is there any point in trying it in slot 4 (x8) ?
I also see that the card has a molex power connector which I have not used, but I wouldn't have thought this would affect speed.
Any other ideas?
Thanks

USB stick very slow

Hello,
I don't use my USB stick very often, so only today I've found that copying from/to USB is VERY slow (~10kb/s). I remember that some time ago the speed was fast enough. What is wrong, why USB is so slow now?

I recently had to reinstall my system due to a corrupted pacman database.
This is the first time I used my usb sticks and cardreader since the reinstall, and the speed is very slow. It now takes 1.5 hours to transfer 100Mbs of data to and from my usb sticks.
This wasn't the case before I reinstalled: It only took under a minute to transfer 100+Mbs of data.
My fstab:

2.4GHZ clients very slow speeds with AP3600

5508 WLC (7.5.102)
AP36021
We currently have a test WiFi SSID setup that uses basic mac filtering on our WLC's
WLAN is configured with WPA and WPA2 L2 Security with WPA Policy and WPA2 Encryption.
For some reason we seem to be getting very slow speeds on clients with 2.4GHZ
for example speedtest.net I get 70mg upload and 65mg download on 5GHZ devices and about 1-3mg download and 1mg upload for 2.4GZ devices!
AP36021 are dual band with 4 channels (2 x 2.4Ghz and 2 x 5Ghz)
fyi - There are no dropped packets on the client stats via Prime mgmt that use 2.4GHZ
Any ideas here?

EA4500 - can only access youtube, google at a very slow speed, can not access anyother website

Got a new EA4500 for X'mas
After setting up the new router I could only access youtube and google at a very slow speed, however I can not access anyother website - facebook, yahoo and etc...
it would ping yahoo and google no problem
friend told me to do a tracert some ip address and his conclusion was the router is fully functional
ISP uses PPPoE, Im sure that the username and password are correct.
upgraded to the latest firmware manually, and holy hell accessing the router with no internet access is a pain in the **bleep**!
Please help and Merry X'mas

It might be a DNS problem. Release & renew ip on the status page of your router. Just make sure you are already using the latest Linksys smart wifi firmware, reset the router & reconfigure. You can download the firmware here http://homesupport.cisco.com/en-us/support/routers/EA4500.

Very Slow Speed & BT seem unable to fix

Hi All,
First time post and would very much welcome anyone’s view on my problem.
Apologies if it’s a bit long!
The problem: Very slow download speed, going as low as 50kbs. Prior to this issue my download speed was around 4.5Mb but since this issue started it has reduced to around 1Mb first thing in the morning which decreases as the day goes on.
The results of a previous BT speedtest were Download Speed 190Kb / DSL connection rate 6.62 Mb (Downstream) / 448Kb (Upstream) IP Profile for line 5Mb
(All tests were carried out using a single Windows 7 desktop pc with a wired connection to a home hub 2)
6 Feb – Contacted BT to advise of speed problem and was informed that they would need to run a test which would take 48 hours.
8 Feb – Contacted BT to be advised it could be a problem with the home hub or network not passing signal. Further line test carried out and was told that it is not a fault within my property. They would pass problem to Network Faults Dept so they could reconfigure the line and they would call me 9 Feb.
9 Feb – BT Called and following a search on this site I mentioned that the noise margin seemed high (13.3dB/26.0dB) He said it should be 6dB and put in a request for it to be lowered and was told the speed should increase by 11 Feb. (Noise margin was under 6dB by the next day)
10 Feb – BT (Level 2 Help) called to advise the broadband connection is in the stabilisation phase.
11 Feb – Called BT to advise no change in speed. They run test and now say fault is inside the house and an engineer would be required. Oh and it would be a chargeable visit. I queried this as the advisor I spoke to 8 Feb said it was not a problem inside the house but his response was that it was originally a network fault, which was fixed, but now it is a problem inside the house. Sounds Fishy!
Call was transferred to the department that arrange engineers and to cut a long story short it was agreed that it would not be chargeable visit.
13 Feb – BT called to advise an engineer visit 14 Feb
14 Feb – Openreach engineer tested wiring and all was OK. Just to be double sure he replaced the master socket to a 2 port type (hub in top port and telephone in bottom) and was told this type does not require a DSL filter. He also changed the Home Hub 2 to a Home Hub 3 and after still no improvement he concluded BT were throttling my broadband. I’m not sure if he reset my profile but said it should start to improve over the next couple of days.
16 Feb – Still no improvement so I called BT again. They wanted to test the line again and it apparently came back with a network fault and it would take another 48 hours. I then asked to speak to a Manager who reviewed my problem history and transferred me to someone in the Network Department. She did a bit of tinkering and the speed went from 200kb to 400kb, then another bit of tinkering and it went to 550kb. At last, i thought, we were making slow progress but since this call, the speed has decreased again to 130kb. She said that I have to wait another 4 days for it to possibly improve and will call me 21 Feb. They keep telling me I have to wait 48 hours here, 3 days there but unfortunately I now have little faith that there will be any improvements in 4 days time. Is this acceptable or am I being too impatient.

WRT54G always reseting and very slow speeds.

I don't know whats going on, I have a WRT54G router thats completely up to date with the firmware and the such. I am connected to it via Ethernet cable, and only use the wireless part for my videogame stuff, so its not just the wireless network thats messing up, its the hardwired that is losing connection. Every half hour or so the router loses its connection and I'll either have to just wait for it to reconnect or have to power down the router (and sometimes the modem, or restarting the whole computer) and power it back up for it to be able to connect again. I have tried completely reseting the routers settings and uninstalling the EasyLink Advisor and reinstalling that and reconfiguring the router but its still doing this. When I am able to connect, my internet speeds are very slow. I am used to getting 200-300k/sec but now I am getting maybe 80k/sec when downloading. Is it possibly my router thats just messed up? thanks in advance(also, when i finished typing this my internet shut down again, and I had to restart the computer multiple times and now im just plugged into the modem so i get a stable connection..)

access the router's web interface and try changing the MTU size to 1400 / 1300 .. check whether this makes any difference..

Very slow speeds and ridiculous email and bill for...

Hi
i have several issues. I have been a very satisfied customer for over 15 years until early summer of this year:
1. My broadband speeds remain painfully slow despite 3 complaints and investigations. In fact my line is still connected to the test line as I was advised to do and I have never had a call back as promised.
2. I have now received an email message to say I have used 90gb at a cost of £50. This is almost all uploads. i upload nothing and this figure is impossible. Until June my usage was quite small and I came nowhere near my limit on option 2. Nothing has changed with my usage since then. I do not download or stream films and do not upload large quantities. I probably would stream films, but the slow speed does not allow it.
3. I spent over an hour on the phone trying to sort this out today, but was not helped by a succession of people who barely understood the situation and had even less understanding of customer service. I have now emailed, but have had a message saying it might be 72 hours before a reply.
Any advice would be really helpful as I am at my wits end
Solved!
Go to Solution.

Ok....since the original post the problem has continued. I have spent literally hours on the phone to people who say all the same things and never come up with a solution.
The test results are below. I do not experience speeds as reported. And if I use another tester it correctly comes out as about 1 4 - 1.9. or even lower. The upload usage is still showing as high....but it is just not possible. I have now reset the hub wireless key, but I have not shared this with anyone in range. Apple TV is now disconnected after it was going to take 20 hours to download a film!
I am at my wits end with this and really do not want the hassle of changing provider but even after 20 years BT broadband I am so very close to that.
Any ideas would be appreciated.
Thanks
Julie

Very slow speeds during evening.

Hi there, my bt infinity 2 is very slow during the evening. From 5pm to 1am every night. I have spoken to three others who are connected to the same cabinet as me. All with the same issues.
I contacted BT about 1 month who actually got an engineer to have a look at the cabinet or something, I couldnt really hear what he said on the phone. This fixed the problem for around 3 weeks then the problem came back around 4 days ago.
The issue I am having is that BT are no use on the phone like the first guy was, they all just say they will change my wireless channel on my homehub. Even tho I said I do not use wireless. And I don't even own a homehub so good luck with that. I am asking for a nod to help me out here, as the BT call centre guys are useless now.
Exchange: Carstairs
Cabinet: 2
Thanks

As you can see my IP Profile is alot higher than my sync. As when the cabinet reset all lines 5 days ago. My sync was much higher then resycned a day later back to the old speed with peak time issues.
Thanks for the help
A possible solution to your IP Profile being wrong is to reboot your router.
Looks like you have noise on the line - possibly a line fault.
Can you confirm the speedtest was done using wired ethernet, not wireless and not power-line adapters?

It seems that something went very wrong starting with the 8.0.3 update, there are numerous threads about this. Make sure to report this to Apple via http://www.apple.com/feedback/iphoto.html

Very slow speed. Reported but not fixed.

After having very slow up to 20mb speeds and constant disconnections I decided to go for infinity option 2 as I had so many problems with ADSL with constant calls to India and engineers coming out.
The engineer turned up as instructed and fitted the equipment. No problems there. He did say I was the only one to have infinity installed at my local cabinet.
Now the real problems started. I still have disconnection issues but not as many now. And the speed I am receiving is worse than my old up to 20mb service.
I have reported this several times (through the help desk in India !!) and some times an engineer comes out and tests the line, equipment, cabinet and telephones the infinity help desk as it appears they can do things remotely.
Each engineer that turns up says he is not trained to fix the problem and that he has done what he is contractually obliged to do and then leaves, stating to wait 10 days and see if the problem fixes itself.
So it appears I'm in a circle of ringing India and being told to wait 10 days or getting someone out who can't fix it, states to wait 10 days and then leaves with problem not fixed.
What am I to do.
Solved!
Go to Solution.

After getting the mods involved and a fault being raised the fault still hasn't been fixed even through it states on the BT website report and track faults that it has been fixed. An engineer hasn't been out to fix it so I am confused as to what BT have done to attempt to fix my broadband problem
Seriously what do I have to do to get this fixed. It is unacceptable that I'm am paying for a service I'm not getting.
How is this posted screen from BT Speedtest accetpable for BT Infinity Option 2 with speeds stated as 60mb down and 20mbs up as reported by the enginner who fitted it.
Your advise will be greatfully helped as I have tried every option now and stil no fix.

Very Slow Speed - Dodgy Wiring?

My internet speed has never been great, average speed test at 700kb/s down and 300kb/s up. Looking at those websites which show you what speeds people in your area get it seems people just as far from our local exchange are acheiving around 1.5mb/s.
I live in a large house converted into flats and the main phone point is downstairs along with the other 3 flats main phone sockets. I have tested my speed when i plug directly into the test socket and it was exactly the same as when it is connected in my flat.
A week ago my homehub spent about 24 hours not connecting to the internet, the B light just kept flashing orange before what looked like it turned off and started again. Since then the connection has been constant but very slow. Over the last few days the speed has dropped considerably. A speed test i tried yesterday came up with several errors and recorded my download speed at 10kb/s. Today this is what it has recorded:
Download speedachieved during the test was - 115 Kbps
For your connection, the acceptable range of speeds is 50-500 Kbps.
Additional Information:
Your DSL Connection Rate :672 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 500 Kbps
Have tried calling BT many times and they cant seem to find anything wrong, an engineer is due to visit next week, but am hoping someone might have a suggestion for me.
Here is a link to a photo of my main phone point, the wiring doesnt exude efficiency to me. What do you think? My connection is for Flat 3 on the left.

Hmm, the VP's seem fine: http://usertools.plus.net/exchanges/?exchange=Wingham&exact=2284&plugin=vp.
VP = Virtual Path.
Virtual Path is the path which BT use in contention ratio management. It is a virtual 'pipe' which a certain number of users share which has an allocated bandwidth. (For instance: BT set the virtual pipe at 8mb at a contention radio of 50:1 (Home package contention) so basically 50 users are sharing that 8mb of bandwidth).
If a VP status is RED it basically means that the VP is overloaded (Too many users are using the allocated bandwidth). This will result in a major loss in throughput speed. This is also usually a sign that BT need to increase the capacity of the VP to allow more traffic through.
I hope I covered it all

Very slow speed during transferring files between two MacBook Pro by AirPort

I have a MacBooc Pro md101 and my friend have MacBook Pro early 2011 model, when we transfering something a speed is very slow,3 month ago i've the same model like his model ( Early 2011 ) and speed was very fast by airport, but now is slow ! Anyone help me or say why ? Thank you...

If it is wireless to wireless transfer it will go at less than half of the slowest connection..
Check each mac link speed to the Express.. if either of them is far away or using 2.4ghz instead of 5ghz you will lose lots of speed.

USB is very slow...

I've been noticing that any USB drive I plug in has some *REALLY* slow write speeds. This is both in FAT32 and when I do Mac OS Extended (Journaled).
Read speeds seem to be ok. I've tried turning Spotlight off for the drive as well as trying the 2 different USB ports to see if one was "faster," but that's not the case.
XBench shows for Sequential Write/Read:
Uncached Write 0.95 (0.59 MB/sec ([4 blocks])
Uncached Write 0.84 (0.47 MB/sec ([256 blocks])
Uncached Read 20.74 (6.07 MB/sec)
Uncached Read 59.48 (29.90 MB/sec)
As you can see, the write speeds are abnormally slow. I'm open to suggestions on what might be the cause (and how to fix). As it stands, transfers of files to my iPhone never really seem to be slow from either port...

Could be that it is only a 1.1 hub, instead of 2.0.....?
see > USB 2.0, Hi-Speed USB FAQ
You won't be sorry using a Belkin 4 or 7 Port self-powered hub.
