Satellite WLAN A665-11Z - WLan 802.11n slow

Hello,
I'm having this problem with my network being SO slow (sometime disconnects for no reason)..
I mean it's really really getting so irritating! (to the point of wanting to smash the Laptop -.-!)
I have:
Realtek PCIe GBE Family Controller
Broadcom 802.11n
(these are the latest version)
My 2 sisters have other types of Toshiba Laptop.. but they don't have the same problem as mine..
I tried changing Power Saving (max performence) <------ didn't work.
I looked in the internet & there was a solution telling to
change the Broadcom(or any other device) from 802.11n to 802.11g.. but I don't know how to do it..
So please!! I mean PLEASE!! help me Dx.. I really can't handle it..
thanx ^^;

Go to device manager -> Wlan card -> Properties -> Advanced tab
Switch from 802.11N to 802.11.G
Click ok
Reboot the notebook

Upgrade mini to WLAN 802.11n

I plan to buy an Mac mini and have a question:
Can you please tell me your experiences with external USB WLAN 802.11n sticks or is it possible to upgrade the internal Airport chip to 802.11n (it was possible on my Macbook Pro core2Duo) but Apple say it is impossible with the mini.
What about this USB WLAN stick ?

Unfortunately, there is no-one here who can answer that since we're all just users such as yourself. The lack of clarity in that document has been reported to the hosts previously with a view to it being brought to the attention of whomever is responsible for reviewing and revising it, but other than that, we have no way to know why the mini is not more clearly identified as excluded from 11n compatibility.

Late 2007 Macbook Pro 802.11n slow transmit rate

I have a Netgear Rangemax N router. But when I connect to the network and option+click on the wifi, my PHY Mode says "802.11n" but my transmit rate is only 54. When my Macbook air connects to the same router, the PHY Mode is still 802.11n, but my transmit is 170. What is happening that my Macbook Pro is connecting slower than the Macbook Air when on the same network?

When I read "crash," "distorted line across my screen," "it gets really hot," and "2007 17" MacBook Pro," the first thing that comes to mind is logic/graphics board. Visit your local Apple Store, and see if they can validate this suspicion or not. The SMART utility reading usually precedes a drive failure, but it's hard to conclude what's happening here.
In the meantime, make sure you're completely backed up. If you don't back up, purchase an external HD, and back up with SuperDuper. Preserve your machine by running things at lower temperatures (under 160•F), and keep an eye on iStat.
Oh, and tell us the problem when you know.

Airport extreme (802.11n) and airport exress

Hi, I was hoping someone may be able to provide some advice. I am considering upgrading to the AE (802.11n). However, I am fairly certain that I will need to have a second point somewhere in my home to boost the signal. I have an airport express for airtunes purposes and have read that connecting 802.11g to an 802.11n slows down the network, but does anyone have any specifics? Also any idea of distance capabilities for the new AE? I have three floors I need to provide signal to in my home, currently I have it set up with D-link router and a repeater in a dead area.
Any advice is greatly appreciated.

Hello Kevin Gamarello. Welcome to the Apple Discussions!
I have an airport express for airtunes purposes and have read that connecting 802.11g to an 802.11n slows down the network, but does anyone have any specifics?
Adding "g" devices to a "n" network will reduce the performance slightly, but not all the way down to "g."
Also any idea of distance capabilities for the new AE?
The new 802.11n AirPort Extreme Base Station (AEBSn) has an advertised range of "up to twice the range of networks created with the earlier 802.11g standard." However "actual performance will vary based on range, connection rate, site conditions, size of network, and other factors. Range will vary with site conditions." In comparison, the earlier 802.11g version had a range of 50' for 802.11g & 150' for 802.11b.

WRT330N and DELL 1505 Draft 802.11n WLAN Mini-Card Rev 2.0

Well it was time to upgrade the house with two new DELL Inspiron 530s.
Each with their own "DELL 1505 Draft 802.11n WLAN Mini-Card Rev 2.0"
Now the (problem) we are having is we are lucky to get 13.0 Mbps & that's if we stay online. Our World of Warcraft gets booted a lot. Which makes gaming hard when I purchased the WRT330N for gaming.
We have the latest drivers for the Wirelss adapters, Firmware is up to date.
Setup is as follows.
Wireless Setting:
Network: Wirelss-N Mixed
Wireless Name (SSID): My own thing there
Radio Band: Wide - 40 MHz channel

Any suggestions?

I am having the same issues. I have the same router but a different laptop. Mine is a Inspiron 1545 with an Intel 5100 AGN card. So the solution is to ditch the Linksys router and get a D-Link? what say you Linksys

Numerous problems with Airport Express 802.11n with DSL and extending WLAN

Hi all,
I have the following hardware:
802.11b/g Airport Express with firmware 6.3
802.11n Airport Express with firmware 7.3.2
MacBook Pro
iBook G4
Mac Pro PowerMac 2x450 G4
Up until now I had been using the old Airport Express as the base station connecting to my PPPoE DSL line, and it worked fine. I wanted to extend the range of this network, and got another newer Airport Express, the 802.11n model.
First I tried to use the 802.11n to connect to the Internet and the old one to extend the network. Turns out the old one can't be used to extend a network, which is bad enough, but the 802.11n one refuses to connect via DSL for more than a couple minutes, then drops the Internet connection.
So I tried downgrading the firmware to 7.3.0 and 7.3.1, but it didn't help. Did a hard reset, factory default reset, soft reset, nothing worked.
Next I tried swapping the two, putting the old Express back on the DSL line and the new one as the bridge to extend the network (using WPA2). But the 802.11n complains that it can't access the network and flashes amber.
Again, tried upgrading to 7.3.2, downgrading to 7.3.1 and 7.3.0, hard reset, soft reset. Nothing works.
Any ideas?
Cheers,
Fairfax71

I don't see any option in the Airport Admin Utility for the old Express for creating a WDS network, only to participate in one...?
That is the option you want to choose.
You could use the newer AirPort Utility to configure the older AX.
Sorry, forgot to ask something else: The 802.11n Express is able to join the WLAN created by the 802.11b/g Express as a client, but not extend it, is that what you're saying?
No. If you join the network the AX is simply acting as another wireless client and is not extending the network. The "extend" option is not available since the older AX is not 802.11n capable. You must use WDS.
Use AirPort Utiity and follow these steps for both AX's. To set up the main AX:
Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as the main base station.
Open AirPort Utility (located in the Utilities folder in the Applications folder on a Mac, or in Start > All Programs > AirPort on a Windows computer). Select the main base station, and choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary. If the base station is using the default password of public, you will not be prompted for a password.
Click the Wireless button, and then choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
Click WDS and then choose “WDS main” from the WDS Mode pop-up menu.
Select the “Allow wireless clients” checkbox if you want client computers to connect to this base station.
Click the Add button and enter the MAC address of the base stations you want to connect to this base station. If there is a base station listed that you’d like to remove from the list, select the base station and click the Delete (–) button.
Click Update to send the new settings to the base stations in the WDS. By default, the “Allow wireless clients” checkbox is selected. If you deselect the checkbox, and later want to change the settings on the base station, you must connect to the base station’s LAN port with an Ethernet cable. You will not be able to connect to the base station wirelessly.
To set up the second AX to connect to the main AX:
Open AirPort Utility. Select the AX, and choose Manual Setup from the Base Station menu. Enter the base station password, if necessary. If the base station is using the default password of public, you will not be prompted for a password.
Enter the same network password as the main base station, if necessary.
Click the AirPort button, and then click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and choose the same channel as the main base station from the Channel pop-up menu.
Click WDS and choose “WDS remote” from the pop-up menu.
Enter the MAC address of the main base station in the WDS Main field. The MAC address is also referred to as the AirPort ID and is printed on the label on the bottom of the base station.
Click Update to transfer the settings to the base station.
This can be found on page 42 of "Designing AirPort Networks Using AirPort Utility" (direct PDF download).

WLC with 2 WLANs, 1 voice @ 2.4GHz and 1 data @ 5GHz 802.11n

I have a WLC 4400 series and am using 1142n APs. Am planning on adding Wireless IP Phones such as 7921/7925 as well as a couple 9971's. Is it possible to have 2 WLANs, one to connect the voice endpoints to running @ 2.4GHz and another WLAN with a different SSID for data clients @ 5GHz? All data clients have 802.11n NICs and can operate @ 5GHz. I have enough APs so that the lessened range of 5GHz won't pose any issues. Ideally I'd like to see connection rates in the 240mbps-300mbps range on the data clients with data throughput rates of 100mbps+ (I don't think this ought to be an issue, I'm aware that wireless is half-duplex and that connection rates do not necessarily indicate actual throughput rates). I am also NOT a wireless expert. I'm still fairly new to working with the WLC and the managed APs as such.
The reason for 2.4GHz and 5GHz simultaneously is that the voice endpoints are all 2.4GHz radios, I believe 802.11b/g. I also want to keep voice clients separate. This way, I believe I can optimize one WLAN for data clients without having them "suffer" so to speak by having to operate at a lower level as the voice clients. Also, I want the voice separate for quality there (separate voice VLAN). If I am correct, 802.11n data rates can also be achieved @ 2.4GHz, but only using the 20MHz as opposed to 40MHz width. So I'd like one WLAN to be 2.4GHz, 20MHz (voice) and the other WLAN 5GHz, 40MHz (data).
I'd like to hav both WLANs broadcasted from all the APs simultaneously. Am I correct that such a configuration is possible with the WLC 4400 series and Aironet 1142n APs? WLC is running 7.0.240 btw, current stable. I'm also starting with a clean config on the WLC. All DHCP will be handled by an external DHCP server also. Thank you very much for any suggestions/guidance on this. Your thoughts are greatly appreciated!
I'll be happ to supply any config information to assist with this, just let me know what is desired/useful.

Thank you for your prompt response. I only have 1 WLC, it is a 4402-50. I believe that 7.0.240 is the most current release for that model. I think anything higher I need to go to the WLC5508 (or vWLC?)
Also, I wasn't aware that the 7921/25 were 5GHz, since they are both 802.11g. Thank you for the information.
If I understand you correctly, I'm best creating 2 WLANs, but both at 5.0GHz for both data and voice?
Also, sorry to confuse the issue further, but I was thinking about this after writing the original post, I'd like to also have a "guest" WLAN that supports both 2.4GHz and 5.0GHz for maximum client compatibility (as I have no way of knowing what tpye of WLAN NIC would be in guest devices). Am I correct in assuming that I would create a separate WLAN for all these, including a separate SSID.
The part that is confusing me some now is the "AP Groups". Do I leave a single "Default-group" and create multiple WLANs with that. If I'm correct, this way I can push the WLANs and SSIDs out through all the WAPs in that group. I want these WLANs to be available from any AP in the organization, not have some APs for one WLAN, other APs for another WLAN, etc.

802.11n doesn't work for WLAN created using WCS templates

But works when enabled on the controller
WLC 5508 - 7.0.116.0
WCS - running firmware 7.0.172.0
Clean Air AP used for testing -LAP 3500
Anyone aware of this issue?
Thanks

Hi,
Thanks for sharing that template.. Now can you take a snapshot of Security and QOS and Advanced tab.
ON WCS by default wmm = disabled and on WLC it is enabled by default.
Check 802.11n to see what needs to be enabled to get it to work.

Satellite Pro A200-16YT - Wireless adapter card upgrade to 802.11n

Satellite Pro is A200-16YT (PSAE1E) with Windows XP Professional SP3.
I have been trying to increase my existing 54 Mb/s wireless network speed by replacing the existing Atheros AR5007-EG 802.11a/b/g with the faster 802.11n adapter.
The Atheros driver is v9.2.0.439 (04/08/2011) which I believe is the latest. I have tried to install an Azurewave AR5BXB72 (Atheros AR5008) as a replacement, but with no success. As well as trying the standard Windows Wireless set-up, I have used the Atheros Client Utility (ACU) which confirms that the card and driver are installed and enabled, but the radio does not switch on, so no there is no association/connection with any wireless network!
Reinstalling the original AR5007 works without any problems. If anyone has experienced similar problems and/or can offer a solution, it would be greatly appreciated. Thanks

Thank you MasterG.
I followed the link you posted and you were correct in suggesting that a WLAN card pin assignment was an issue.
On older cards, (before Revision 1.2 of the PCI Express Mini Card Electromechanical Specification), *Pin 20* was +'reserved for future wireless disable signal (if needed)'+, so presumably on my Toshiba Satellite A200, disabling the old AR2007 card was handled by the system software and the Wireless ON/OFF switch.
On the newer adapter cards, Pin 20 is assigned to a *W_DISABLE#* signal which, when low, will disable the radio.
As suggested by other posts, masking Pin 20 on the AR5008 card has prevented the radio from being disabled, and the only small problem with this is the radio can no longer be switched off with the Wireless ON/OFF switch (or with Function+F8).
However, the wireless speed is now 144.4Mbps, enabling BT Infinity broadband download speeds in excess of 30Mbps.
Your assistance is very much appreciated.

Airport Drives Me CRAZY! New 802.11n Network Slower Than Old 802.11g/b

I've been using Macs since 1988 and consider myself an advanced user. However, every time I setup a new Airport wireless network or re-configure an existing one, I feel like a helpless newbie trying to figure out how to open a folder on my desktop. No matter how many times I read the manual or the help files or these forums, I can never grasp what seems like it should be a simple path from A to B to C.
Anyway, here's my current situation: I've been successfully (I think) running a 6 year old AP Extreme Base Station [AE] (in my home office addition) and 2 Airport Expresses [AX] (one AX roughly 15 feet from the base station--through sheetrock, and the second AX roughly 30 feet from the first AX--through sheetrock and some wooden stairs. (so roughly 45 feet from AE to 2nd AX). It wasn't the speediest thing going but it did the trick with older Macs.
I recently bought a MacBook Pro which supports 802.11n. I most often use this laptop at the point in the house furthest away from the AE (Base Station) The AE (Base Station) is in my home office connected to my MacPro desktop (see #1 below). In addition, the family iMac is also in that room furthest from the AE. Using the new MacBook Pro with the old 802.11/g/b network turned out to be painfully slow. I was experiencing the same slow network connection my family has complained about for years with their older Macs and 802.11g/b.
I decided it was time to upgrade the whole network, if only to speed up my MacBook Pro connection. Bought new 802.11n Airport Extreme (MC340LL/A) and 2 new 802.11n Airport Expresses (MB321LL/A). Setup did not go smoothly. Again, my normally competent Mac persona was reduced to a babbling three-year-old. Had three different Apple techs on the phone trying to help me through it. Got different, contradictory instructions from the last two. Finally got all three units working, only to find that not only does my MacBook Pro seem even more sluggish than when connected to the old 802.11g/b network, but my wife tells me web pages are taking at least twice as long to load as with the old network.
As concisely as I can lay this out:
*1. Airport Extreme (Base Station)*
Connected via Ethernet from its WAN port to my Comcast cable modem. One Ethernet (LAN) port on that AE is then connected via Ethernet to my Netgear 8-port Ethernet switch. Ethernet from switch to Ethernet port 1 on my MacPro. (MacPro does NOT have an Airport card because I forgot to order one. Also I confirmed that this setup was functional by connecting to the AE wirelessly with my MacBook Pro showing the name I'd given the new network prior to adding the two AX's to the mix).
Some Airport Extreme settings of note (all accessed via "Manual Setup" button):

SETUP/GOALS:
With Airport Extreme (Base Station) as the starting point, have the two Airport Express units with the strongest, fastest signal possible, provide Internet access (and file sharing, iTunes speakers capability) to three Macs (one older iMac, one older PowerBook and my new MacBookPro). Again, I believe my new MacBook Pro is the only one with 802.11n support, so I don't expect the other Macs to take advantage of the speed boost offered by the three new 802.11n devices.
+Any and all help with this will be greatly appreciated. Thanks!+

{quote}With the AirPort Extreme, in the AirPort panel, Wireless tab, click on the button for "Wireless Network Options", check the box for "5 GHz Network Name", and enter a different network name. (That can be trivially different, such as the name of the main network suffixed with an underscore and the digit 5.) Once configured that way, connect your "N" gear to each network in turn to see if one is any better than the other. (If you're wondering what effect this would have, it allows segregating your "N" gear from the older gear to prevent the older gear from slowing down your network. However, distance and interference from things like walls may negate any advantage.){quote}
William: I was gone most of yesterday, but had a chance to implement your recommendations today. I added the 5 GHz network as you suggested, but in order to connect to that at all with my 802.n11 MacBokk Pro, I need to be within a few feet of the AE (base station). If I try to access that network even from the next room (well within reach of both the AE and the livingroom AX, I get one bar and "failure to connect" messages just trying to logon to that network.
However, I did some experimenting that (as of right now, anyway) resulted in much faster network access, not only from my MacBook, but also from the older iMac which is the furthest Mac from the AE. According to my wife, that iMac is "loading web pages faster than I've ever seen them!"
Here's what I did:
1. Moved all three units to places where it seemed they would have the least amount of interference with the clearest path from unit to unit, also raising the height of both AXs from about 2-3 feet from the floor to about 5-6 feet from the floor.
2. Changed one setting on the AE (base station): Wireless Tab > Wireless Network Options > Multicast Rate ---> Changed this from Low to High.
I have a feeling the location shifts made the real difference, but I will try changing the multicast rate back to "Low" just to see what happens.

Does Mixing 802.11n with .11g Devices Slow the Whole Network?

Hi all,
I'm considering buying the new Airport Extreme as I also have a new Macbook Pro that supports 802.11n. I also have a couple Airport Expresses on my network, and my question is this:
Will the presence of the Airport Express units (which are 802.11g) drag the whole network into .11g speeds? I ask this because of this note on the Airport Extreme page:
Speed and range will be less if an 802.11a/b/g product joins the network.
Thanks for any guidance.

I did this the same way....
I connected my cable modem directly to the WAN port of my new 802.11n AirPort Extreme Base Station. I have selected 'n' only (5GHz). I call this network Saturn.
There are 3 ethernet ports on this new base station. Wired to one of these ports is my 802.11g Snow Airport Extreme Base Station. This base station will handle any 'g' services (like my friends who are using MacBooks/iBooks/PCs). I have 2 AirPort Express base stations that I use to play music on remote speakers, and wireless printing. It also has 2 Linksys wireless USB 'b' devices that connect to it, which 2 of my TiVos use to get their daily updates. I wanted to keep all of this stuff off the 'n' network since I heard it would slow it down. I call this 'g' network Zodiak. I can see both networks in my AirPort menu, and can select either.
In addition, I have an xBox that I connected directly to one of the wired ethernet ports on the 'n' base station, and I have a Linksys switch that is wired to the 'g' base station.
My only complaint is that I can't get to all of this stuff that is on the 'g' network. Which means, if I want to print something, I need to change my network, if I want to play iTunes out of my stereo speakers, I need to change the network, and if I want to use my TiVo to display photos, I need to change networks. I was hoping I'd still be able to get to that stuff since the 'g' network is hard wired into the ethernet port of the 'n' network. Oh well. I'm only on a 6MB Comcast service, so perhaps I'll try mixing the 'g' network in and seeing how bad it affects performance.
I'm getting 2.5 mb/sec on a hard drive transfer...can't imagine that being much worse on 'g'.

USING TWO AIRPORT EXTREMES (802.11N) INTERNET IS VERY SLOW

I live in a 5000sq ranch in arizona and have our internet set up in one end of the house. We have an airport extreme 802.11n and it wasnt putting out a good signal to the other end of the house so we got another airport extreme and airport express to expand out network. By the way both are 802.11n and the internet is still not even usable because it is so slow. The only computer that has some sort of speed is the mac tower that is hardwired to the airport. PLEASE HELP!!!!!!!!!!!!!!!!

If you could ethernet the two Extreme N routers(try to place the second further into the house) and set the second in bridge mode and set to create its own wireless networrk. Use the manual configuration. The third can join the second, signal should reach and be strong. This must be in bridge mode also.
there are many different ways to set the configuration for wireless but the bridge mode is a must do.

Slow wireless connection 802.11n AEBS and Intel Core 2 Duo MacBook Pro

I have three Macs all currently connected wirelessly to the new 802.11n AEBS.
Mac #1 - PowerMac G5
Mac #2 - 17" MacBook Pro Intel Core Duo
Mac #3 - 15" MacBook Pro Intel Core 2 Duo
The wireless connection speed (when using the web browser) is fine for both Mac #1 and Mac #2 but noticable slower for Mac #3. All three Macs are sitting right next to each other. All three Mac are getting an excellent signal. All three Macs are running the same version of the OS. All three Macs have identical network setting (as far as I can tell).
When connecting Mac #3 to the AEBS via an ethernet cable, performance is good. I've also tried configuring the channel manually in the AEBS to channel #1 but this did not help (seemed to help others in a different thread). Additionally, I ran the 802.11n enabler and performance was bad both before and after its installation.
Any idea why the Intel Core 2 Duo MacBook Pro would be performing differently?

Ok eveyone. I did some digging and was able to get the network speed back with my Core2Duo machine. I put the Airport Extreme into Bridged mode and connected the Ethernet cable to one of the LAN ports, not the WAN port. After that everything works great. for more information check out this lengthy thread...
http://discussions.apple.com/thread.jspa?messageID=3989864&#3989864
and this site mentioned...

Apparently the new base stations have a few issues that need to be worked out so I'd consider this a workaround. There should be no reason to have to do this. Good luck.

Very slow 802.11n. 20" iMac, Vista, Broadcom, Belkin N1

I've been trying to get some drivers working with Windows Vista. I'll post the results I've been having and maybe someone can assist.
I have a 20" brand new iMac with Leopard running bootcamp windows vista ultimate. When I connect to a Belkin Pre-N wireless router I get 802.11g wireless speeds(expected) of about 36mb/s (it's a good distance away, 2 bars).
I have another wireless router Belkin N1 wireless and I get differing wireless speeds/connectivity depending on what drivers I use. I have 5 full bars and an "excellent" connection rating for it.
I understand that the specifications for 802.11n that both belkin and apple use are based on draft specifications and may not be compatible.
The drivers on the leopard disk are marked as 4.80.75.0. I can connect using those and use the internet. But at very, very slow speeds (27.0 mb/s Broadband tests show .5% of normal speeds for my provider, a wired connection will get 105.8% of normal speeds for my provider.)
I got some other drivers that were posted by other users at the following location
(http://www.versiontracker.com/php/dlpage.php?id=115683&db=win&pid=149836&kind=&l nk=ftp%3A%2F%2Fftp.support.acer-euro.com%2Fnotebook%2Ftravelmate_2480%2Fvista%2F Drivers%2F802.11b%2BgBroadcom+Wireless+Lan+Driver4.102.15.61.zip)
Those drivers are marked as 4.102.15.61. It will connect 1 out of 7 tries at 270mb/s but will disconnect after a few seconds.
There are some other drivers posted by another user at the following location:

These are marked as 4.150.31.0. Same issue as the ones on the leopard disk. I get connectivity, but at very slow speeds.
I believe I have the most up to date firmware for my router but will check that and post on the message board some results. Another option that I have is to completely disable the 802.11n protocol on the router and just use 802.11g.
Does anyone know any other drivers out there that I could try? I will post findings. Again this is only a problem while trying to connect to a Belkin N1 wireless router. I get much better speeds/connection using a Belkin Pre-N router.

I have a 24" Core 2 Duo iMac (2.4 GHz, 4 GB RAM) running Leopard and an Apple Airport Extreme base station, and am having the same problem with slow wireless speed under Vista Ultimate edition with Boot Camp. All Vista software updates as of March 11, 2008 have been applied.
I've reinstalled the driver from the Leopard disk (no effect) and updated the driver directly in Windows, using the one that Windows detects automatically (no effect). Under OS X, I get close to optimal bandwidth over the 802.11n connection to my cable modem. The Airport Extreme is set to use 5 GHz only and does not use the 802.11g-compatibility mode.
When I use a wired connection to my gigabit Ethernet switch, everything is fine.

AEBS (802.11n, A1143) AirDisk transfer slows to a crawl!

http://discussions.apple.com/thread.jspa?threadID=1140924
^ this thread describes exactly my issue with the AEBS (the first 802.11n model) ....
I have an external drive connected to the USB of the AEBS, to be used as an airdisk.
After about 10GB of transfer or so (it varies), the transfer rate will drop from about 5-7MB to about 23KB, and stay that way until I restart the AEBS!!!!
Has anyone fixed this issue?
7.4.2 firmware

I can't get 7.4.x to run well, plagued by slow Airdisk speeds.
I'm running 7.3.2 and everything's fine.
I'm considering selling my AEBS and getting the current model with 7.5.x in the hope of faster performance.
