Setting Link Speed on VPN Virtual Adapter

The link speed for the VPN Adapter used by the VPN Client is normally 1GB. Does anyone know how to chnage this? Some of my users are trying to use the feature in Outlook that will block large attachments when connected to a slow (dilaup) connection. Outlook however sees tha 1GB connection and does not block the attachments.

With a dual band AirPort Extreme, both the 2.4 GHz band and 5 GHz band are being broadcast with the same network name. A computer, or your AirPort Express, will connect to the band with the best (strongest) signal.
Without knowing anything about the layout of your home and location of your devices, my guess would be that the extending AirPort Express sees a better signal at 2.4 GHz, so that is what it extends. Remember, the AirPort Express cannot extend both the 2.4 GHz band and 5 GHz band at the same time.
If the iMac is closer to the AirPort Express than it is to the AirPort Extreme, it's going to pick up the signal from the AirPort Express.
Is that a possibility?

VPN Virtual Adapter and Vista

I am running Vista for Business on my notebook and have installed VPN Client version 5.0.02.0090
Each time I try to connect to my network the VPN client times out and I get the message
Secure VPN Connection terminated locally by the Client
Reason 442: Failed to enable Virtual Adapter
When I go to Device Manager and enable the VPN network adapter, it becomes disabled once I try to connect again.
I tried the softpedia.com/Tweak fix and it worked the first time I tried to connect, but once I disconnected the error came back again at subsequent tries.
This is pretty frustrating. Plse help. Thanx.

OK, I have come a little bit further with this problem. Some recent automatic updates by Windows Vista caused the client to stop working when it was working before.
I uninstalled all the updates (most were critical security patches which now leaves me vulnerable) and uninstalled the Cisco VPN client including scouring the Registry for anything remotely associated with the VPN such as any reference to 'CVPN' or 'Cisco'.
I then installed the latest VPN client (V 5.0.03.0560), and I DIDN'T reboot as it asked me too. The reason I thought this was a good idea is because after a reboot, the Network Connections are reset and re-assigned IPs which was, I started to think, part of the problem.
It Worked! I was able to start the client (that was already an achievement!) and, lo and behold, was able to connect without problems... I thought!
Now I have the following... when I connected to the VPN, I have limited access to the internet. Some sites are fine, others only load half-way and still others I can absolutely not connect to. The ones I can connect to load very very slow.
For now I have left it this way since I can (albeit handicapped) connect to the VPN so I have to keep connecting/disconnecting etc. It is still very frustrating.
However, I believe I know what the problem is, but I don't know how to solve it. If anyone here can use this information to take this one step further, we may get somewhere.
I believe it has to do with the TCP/IP settings where we now have both v4 and v6 running. I think the VPN is using one of these only, and when it is using it, it is not allowing any other traffic through it. I don't know how to solve this. I tried disabling one or the other in either Network Connection, but it either gives me no connection or limited connection.
The reason I think this is it is because some sites are loading/half loading when the VPN is connected... in other words, one of the TCP/IP protocals is open to the Internt traffic, the other is used by the VPN exclusively.
I tried looking for sharing and tunneling options in my VPN client and the Network Connections settings, but I can't find anything.
I am very hesitant to change any more settings since I do have a half-baked solution that at least allows me to meet the deadlines I have for my client.
Let's get this solved!

How do I set Link Speed and Duplex Mode of NIC Card

Hi All.
I

I'm working on the tester to verify the various speed at UUT by sending command on those speed and check response.
I used to try Devcon but only disable and enable NIC Card that I know for now. If someone experience on this thing, that would be great.

Macbook pro and wnr834b gets only 130 link speed

i have a macbook pro with the "n" enabled and when i connect to my wnr834b which is an "n" router i only get link speed at 130 instead of 270 which it should be and what it is with all my other computers in the house. how do i get my mbp to connect with 270 link speed? i have the security disabled and have the channels set to auto. please help.

Here's the odd thing: in Windows XP Pro (under Boot Camp,) the wireless adapter connects @ a very stable 270mbps. On my PowerBook G4, with an nQuicky cardbus card ( http://www.quickertek.com ), it also connects at a stable 270mbps. I've got a Belkin Wireless N router.

MSI RD480 Neo2 : HT Link Speed

I've just discovered the HT Link Speed limitation in the current 3.2 bios for the MSI RD480 Neo2 and was wondering if MSI is able/going to fix this issue? and add if possible the 2x,3x,4x,etc HTT links??
Previously this was not an issue since i had an AMD Athlon 3400 (with an AMD set 4x HTT multiplier), this created a HT link of 1,000Mhz when running my cpu/memory to 250 mhz. However with my newer X2 4200 which is factory set at 5x, I'm hitting the HT max mhz limit pretty quick..
For the moment i can set the HT Link from Auto to 200, however the limited bandwidth is really chocking the system.
Regards,

Thanks for the reply Bosskiller.
In the RD480 3.2 bios there are only two options for HT Links. Auto and 200... (it's interesting, the popup menu gives the feel that there was plans for more options.)
From my testing, "auto" seems to take the HT speed burned in by AMD. (800 HT (4x) or 1000 HT (5x))
I've dropped the cpu divider down to x8 on the x2 4200 (11x factory) and the memory divider to 166 speed (i've ran this pc4000 at 250mhz ddr with this exact mb, just with the single core 3400 (800 HT 4x) cpu. But just to take them out of this issue.
(auto)
215 = 1079.4
220 = 1104
225 = 1129
230 = 1153.8
235 = bios hard lock... (cmos reset)
(200)
235 = 235 (boots just fine, currently running prime on the cpu's.)

Upgraded Mini: Link speed = 130Mbps, Transmit rate = 65Mbps

It was a long night last night. I finally upgraded my old Mini (Late 2006) with a compatible Atheros AR9280 wifi card. It's already been upgraded years ago to 2GHz C2D, SSD, 2GB RAM - running Snow Leopard 10.6.8. So wireless-N is really the last thing to do here.
Installed easy enough. Recognized and connected to my AEBS (2nd gen.) - but only at 65Mbps transmit rate. No matter what - apparently. Network Utility reports Link Speed at 130Mbps possible.
My network:
AEBS (2nd gen): 2.4GHz N-only, WPA2, Can't go to 5GHz - my tablets/phones not compatible, and AEBS (2nd gen) is not dual-band.
LAN-connected: Mac Mini Server (2010), Windows 8 laptop, and my NAS.
WLAN: Windows 7 laptop, above Windows 8 laptop occasionally, 2 pads, 2 phones, and the old Mini in question.
All of the above achieve transmit rates at 117-130Mbps depending on where I'm positioned (except the weaker phones and pads).
Here's what I tried and discovered last night:
[thinking it's interference/distance/signal problem]
1. Positioned the mini 6 inches from AEBS - increased signal to -22, but still 65Mbps.
[thinking it's single vs multiple data stream problem, so then...]
2. Connected the bluetooth antenna as secondary antenna on the card - increased signal, but still 65Mbps.
[thinking it's antenna problems, so then...]
3. Used 2 antennas from parted laptop. No change.
[thinking it's a problem with the wifi card, so then...]
4. Installed the card in an old Windows 7 laptop, installed drivers - Transmits at 130Mbps!!!
[thinking it's a router issue with Macs only, so then...]
5. Turned on wifi at the newer Mac Mini Server (2010) - Also transmits at 130Mbps!!!
[thinking it's Mac OS "registering" my card capabilities as the old 54g card somehow, so then...]
6. Installed fresh 10.6.8. No change.
[thinking it's driver compatibility issue with "IO80211family.kext" version 3.2 (in 10.6.8), so...]
7. Tried the Lion and Mountain Lion versions of kext above (edited as they don't natively see the AR9280) - Not compatible - No card found.
[thinking that a beer would be really good to clear my head, so...]
8. Beer, followed by sleep.
So the card is fine, antennas are fine, router setup is fine (at least for all other machines). It must be one of two things:
A: MacMini (Late 2006) hardware limitation of some kind - Although I have seen others with this upgrade online.
B: Driver/kext issue.
Anybody brave enough to take a stab at this?
Respect -

Thanks for the effort guys -
Tried these two suggestions at the same time, by disconnecting all wireless devices, and setting the AEBS to 11n 5GHz only, and rebooting AEBS and the Mini. Auto channel is the only option in 5GHz - and it chooses channel 100.
Same story: 65Mbps
I'm onto another theory now - The card is not an Apple branded Atheros card, although System Profiler accepts that it is (see above screencaps). It has the same chip, but not the same branding. Note the "Card type" is reported Airport Extreme (0x168c, 0x1c71). In other reports I have seen the second half should be 0x8f for the AR9280 card.
What also bothers me is that "Locale" is "Unknown". On the original 54g card it was "FCC". Perhaps this prevents the card from using its full capabilities?
But the main issue I can't get my head around is that in other failed upgrade efforts I have seen while searching - their card is just not recognized or unsupported, etc. My card works - but not full speed.

Anyone get a 300 Mbit link speed using 40 MHz (Channel-Bonding) on 802.11n?

I recently switched from a MacBook Pro 2.33 C2D 15 to a new MacBook Air 1.86 SSD... For some reason, one little persistent mystery that remains, is that I have been unable to get the Air to establish the link speed at 300 Mbit/s at 40 Mhz (Channel-Bonded). The best I can get is 270 Mbit/s, although my MacBook Pro consistently links at maximum. Signal quality is not an issue...
Anyone have an idea why? Can an Air owner out there confirm max link, or is this little gem incapable of 802.11n wide 300 Mbit/s?
Thanks to anyone who can shed light on this little puzzle...

Thanks for the reply.
First, you need your TC's 'Radio Mode' set to '802.11n only (5 Ghz)' - (I assume you do, since I don't think the 'Use wide channels' option should appear in any other mode...).
Now, the quick method to check Link Speed is in the 'Network Utility' Info tab...
Note that I don't have a major issue with my transfer rates, but do think it's an anomaly for a MacBook Pro to consistently link at 300 Mbit/s and my Air to refuse the same (max 270). In general, I would say that my Air exhibits (a bit) less sensitivity than the Pro with consistent wireless performance (i.e., I never had issues with the Pro acquiring and maintaining wireless links - the Air less so...).
Thanks for your help.

SATA link speed

Hi, this topic didn't appear to be up here yet, so I'm going to ask it. When did the white MacBook switch to the SATA 3.0 Gb/s standard? I recently updated my hard drive to one that has 3.0 capability, but the link speed in the System Profiler says 1.5 only.
Every bit of research I've done tells me that SATA hardware is forward- and backward-compatible, meaning the only thing standing between my new hard drive and its full capability is the MacBook's firmware.
I noticed a recent firmware release for MacBook Pros that "unlocks" the faster standard, and it also mentioned that the newer white MacBooks have it already set up no problem. So my question is: Which model is the earliest capable of SATA 3.0 Gb/s? Also, if my late-2007 MacBook is not compatible...why is that? What is actually responsible for this limitation, if not firmware?
Thanks.
P.S. Your login link malfunctioned in Safari ("404 - We can't find the page you're looking for"). I had to use Firefox to post this message...my Mac was disappointed. Better get your "geniuses" on that

Ah yes, I admit now to have forgotten to search the MacBook Pro discussion posts. That's the only place I now see a date mentioned.
And indeed, this afternoon Safari allowed me to log in, after a week or so of "malfunctioning."
Thanks for the answer, but I would still like to understand what part of the computer is responsible for the 1.5 Gb/s limitation, since serialata.org clearly states that its hardware is forward compatible.
You have an impressive collection of devices; can I have one? :P

I have 300 stores and I'm looking for a global QOS config that would shape/policy the bandwith based on a % of the detected ISP link speed

Hi,
We have 300 stores with mostly the same router config.
The router in each store is a cisco 891 router capable of doing QOS.
Each of our store is connected to internet through a local Internet Service Provider (ISP). They all have different ISP.
Each store has different Internet plan with different speed, some are DSL, other are using cable modem.
The connection between the router and the modem is 100Mbps. But the real speed after the modem will be different depending of the Internet plan the store is using. Exemple : 20Mbps download / 2Mbps upload.
I'm looking for a standard QOS config that would be put in each routeur and that would shape/policy the bandwith based on a % of the detected ISP link speed. The goal here is to prevent a single desktop computer of the store to take all available bandwith of the ISP link because of youtube , cloud photo upload, etc.
Because the wan of the router is in the modem at 100Mbps, I cannot use this bandwith indication for the % calculation. The ISP link speed (after the modem) is much lower than that.
In other words, I dont want to set specific qos value or bandwith manual value in each of my 300 router. Especially because the ISP speed is not the same in each site, it's a big job and it's changing all the time. Stores owner boost their link, etc.
So, Is there a way within the router to detect the Wan real max speed and to assign dynamically % of the deduced value and assign it to different policy-map rules, etc.
regards
Jonathan D

I was looking to address a somewhat similar problem several months ago, and believe I could construct dynamic QoS shaping using an embedded device script working with IP SLA monitoring. However, the "problem" site (using a cable modem) closed, so I didn't pursue it further.
An alternative approach would be to use as few policy models as possible. For example if there are sites with 2, 3 or even 5 Mbps uploads, you might use a 2 Mbps shaper for each. Of course, sites with more available bandwidth won't obtain the full advantage of it, but your maintenance support will be easier. Conversely, especially for cable modems, running under their nominal speed might provide much more predictable performance, as HFCs are generally much more variable in their actual available bandwidth, moment to moment.

Unable to set the speed on dot11Radio Interface

Hello Experts,
I have number of 1130ag access points in our network. The problem i am facing is that when I tried to set the speed on the dot11Radio 0 and 1 interface it doesn't appear
This is the command I am using:
interface dot11Radio 0
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
Please can someone help me.

Hi,
The configurations that you are entering.. that is..
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
is the Default config for 802.11G and by nature the default configurationas will not appear in the running config.. another example is.. By default Aironet Extentions are enabled on the AP runing config, and in the Show run you will see that.. but when you isue the command no dot11 extension aironet thne this command wil show up!! please make the change and then you will be able to see.. here is the link as well which can be used to set the values..

When using Network Utility, does Link Speed tell you the actual speed of the network?

I'm trying to see whether a power line adapter I installed in my home network is faster accessing the internet than the WiFi from my Time Capsule.
Using Apple's Network Utility, my power line/ethernet connection reads as being 1Gb/s, which is obviously much faster than the 130 Mb/s of the WiFi:
But are those the actual speeds my iMac is receiving, or are those just what the specs of the device I'm using should be receiving (as in "ideal, what-the-manufacturer claims the speed should be")?

Are you sure you only want to test internet speed?
Internet speed is affected by many factors that are beyond your control - it is also likely that the internet connection is one of the slowest parts of your network.
You may be on an ISP connection that has 'contention' e.g. a shared connection across many users - their use can effect what rates you get. You will probably see different rates for the time of day too. When everyone gets home & starts watching Netflix you can see drops in speed.
Powerline could be many times faster than the internet connection, in which case you will see no improvement because the bottleneck is not the local network - it's the internet.
To truly see if the powerline adaptors are faster you should take the internet out of the equation. It's fairly simple to do if you have a device on your network that supports file sharing. Ideally you would use another Mac connected via ethernet to the network (that should remain the same in all tests). A Time Capsule could be used if you can write data to a sharepoint.
Copy a large file onto that destination & time it.
Repeat on wifi.
It's best to shutdown any background apps to be sure that other items are not hogging all the data transfer. Take many tests to get a decent average.
Divide the file size by the time taken to see a rough figure for the MB/s (MegaBytes per second) bear in mind that network transfer is usually measured in bits/second, so they won't be the same as the link speed figures.
This is generally smart enough to convert if you give it the correct units…

If you have multiple Macs, iPerf is a free tool to test if you are capable in the command line. JPerf is a version with a UI (needs Java installed).

How does AnyConnect client calculate its Link Speed? (Windows 7)

I'm curious about how the AnyConnect client determines what its default Link Speed is, upon initialization?
For example, from behind my home firewall, if I have a client that's physically connected to a 1Gbps uplink, when I launch the AnyConnect client, Windows Task Manager shows me a Link Speed of 9 Mbps for my AnyConnect connection.
However, if I also launch an AnyConnect connection from another machine on my home LAN, connected via 300Mbps WiFi, Windows Task Manager will only show me around a 1 Mbps Link Speed.
How does the AnyConnect client calculate its Link Speed upon connection?   Does it take a percentage of the available upstream bandwidth?
My home ISP bandwidth is 50Mbps down/12 Mbps up.   My corporate ISP (where the ASA I'm connecting to resides) it 50Mbps bi-directional.

For PHP, if you want to handle data in UTF8, NLS_LANG must be set to
"<language>_<territory>.UTF8", where <language> and <territory> are your
preference. There is few difference between ODBC and OCI called by PHP
in this case as both need to set NLS_LANG to UTF8. If you are familiar
with OCI and expect better performance, you can do so. But if you want
to make the application be portable in terms of data source, ODBC is an
appropriate choice.
Data source doesn't matter the encoding of client. The character set of
client is determined by how client calls ODBC functions SQLBindParameter
or SQLBindCol. If the client specifies SQL_C_WCHAR, data is exchanged in
UTF-16 independent from NLS_LANG. If it is SQL_C_CHAR, data is in
NLS_LANG encoding. Unicode ODBC client binds data with SQL_C_WCHAR, that
is exactly the case of MS Access 2000. On the other hand, because PHP
binds data with SQL_C_CHAR, NLS_LANG is taken as the encoding for data
manipulations
