18 GHz Signals

Dear all,
I'm trying to put together a LabVIEW-based system that can generate and analyze signals up to 18 GHz. NI current Signal Generator and Analyzer cards can go only up to 2.7 GHz. I was told that there is a third party SG and SA that can go up to 18 GHz. My main concern is that I want to have control of the generator and analyzer through programming (LabVIEW), which I'm not sure is possible using any third party stuff. Any advice or suggestion is highly appreciated.

Dear Tim, Andy,
Thanks so much your replies.
Yes, you are right. I am new in the RF, Ku band areas. I've been dealing with data acquisition, on-the-ground and in-flight, previously. Now, the company is looking into 'radar jamming' as well as video telemetry kinda stuff.
Based on Andy's reply, I'll stop wishing for NI's products for my application for now. My fear of using third-party's hardwares and softwares is not to have the flexibility and total control on the system flow, automation... simply said, the system as a whole. This is especially true (as far as I am aware of, that is) if I were to integrate the system with other non-RF systems - control modules, DAQ, etc. I've done this before using all PXI stuff.
I've just went to Rohde & Schwarz's website to look at their spectrum analyzers and also, on LabVIEW drivers availability. I've went to Tektronix's and Agilent's some time back. What I am curious to know is what can one do with the "LabVIEW + FSU Spectrum Analyzer (SA) system for instance? Can the FSU SA somehow be programmed, by LabVIEW, for synchronization, triggering, etc? Also, to what extent of 'control' does the user has?
Perhaps Tim, or anybody else for that matter, can enlighten me on this. Or better, can someone give an example on how he/she has used LabVIEW along with third parties signal generators or spectrum analyzers?
Lastly, I really appreciate the help/'enlightenments' from you guys!!

Retina MacBook Pro is not connecting with Airport Extreme 5 GHz signal

I believe I have done my due diligence to find the answer to my question here and other places but I must be missing it. I have a Retina MacBook Pro that as far as I know should select the 5 GHz signal from my Airport Extreme (Generation 1 with 7.6.4 firmware) which is literally 3 ft. from my computer. When I click on the Airport icon in the menu bar, it is indicating a 2.4 GHz connection. I have looked at discussions which say I can give separate names to to both the 2.4 GHz and 5 GHz signals. I can't seem to find that. I also read where you can reorder the order of signal preference. I can't seem to find that either. Interestingly, I have an Airport Express that is extending the network. When option clicking on its icon in airport utility, I can see both the 2.4 and 5 GHz information. I don't se that in the Airport Extreme. I am thinking about gettng the newest Airport Extreme but if I don't need to...
Thanks for any help!

A Generation 1 AirPort Extreme is not a simultaneous dual band wireless router. It can produce either a 2.4 GHz....or....a 5 GHz wireless network signal, but not both simultaneously.
If you want the Gen 1 Extreme to produce and deliver a 5 GHz wireless network, it can do so, but any 2.4 GHz devices that you have will not be able to connect to the 5 GHz signal.
A new simultaneous dual band AirPort Extreme will produce both a 2.4 GHz and 5 GHz signal simultaneously. Wireless devices will automatically connect to the best signal quality based on their capabilities and location in relation to the AirPort Extreme.

Why does my iPad mini not receive 2.4ghz signal but does receive 5.0 ghz signal?

I have an iPad mini that does not receive a signal from any router on 2.4 ghz, but does receive a signal from the same router if it is 5.0 ghz. Since most public wireless systems broadcast on 2.4 ghz, I am unable to use the mini anywhere except my home office, where I have dual frequency router. I have checked into every technical help site I can find, and most of them suggest resetting the mini, resetting the router, etc. Nothing works so far. Is it possible that the receiver in the mini is defective? Has anyone else had this problem?

There is a problem with iPad Mini's as this has happedned with two separate mini's. I have been to every Apple related site that I can find, and have reset both the units and the Netgear router in my home office numerous times without success. I'm a retired electronics engineer, formerly in Silicon Valley, so I'm reasonably confident that I haven't missed anything obvious in troubleshooting this problem..
I have been to the local Apple store and have had a couple of consultations with the geniuses there. In each case they have confirmed that the units will not receive a 2.4 ghz signal but will receive 5 ghz. Apple stores only have 5 ghz wireless so it took a while for them to understand the problem and I had to connect to a 2.4 ghz system with my iPhone5 to a department store next door before they would believe me. They did take back the first unit and within two weeks the second unit had failed in the same way. 5 ghz OK but no reception on 2.4 ghz. Since most public wireless systems are on 2.4 ghz, the unit is rather worthless when I am travelling.
I use an iPad2, an iPhone5 and a Macbook Air and we have two other iPads in the family, all of which are on the same 2.4 ghz wireles system and all functioning properly. I can only conclude that the 2.4 ghz transmitter/receiver in the iPad mini has a fundamental fault and hopefully Apple will recognize it and have a fix. In this case it will have to be a replacment unit as it's unlikely a technician would be able to replace the electronics in the field.
I would like to hear from anyone who has observed this same problem. Unfortunately, most of the advice on these forums concentrate on resetting the iPad or the router and fail to understand that the problem is hardware related and not software related. Perhaps this could be the beginning of a dialogue and a potential fix for the problem.

Simulate GHz signal with big number of samples

I would like to simulate 650nm wavelength signal with 3.5ms of pulse duration. So I need very high sampling frequency and big samples in LabVIEW, if I go generate about 1M #s, its very long to generate. Is there any solution for that?
When you feel sad, laugh

Just taking a very quick look at your code, my guess for the increasing CPU over time is how the waveform data is being built. Anytime LabVIEW builds an array by appending, rather than having a predefined array that has the elements modified, the program must keep reallocating memory to store the increasingly bigger array. This takes time and CPU, more and more as the data set gets bigger. I'll try and look at it a little more later and see if an easy solution becomes apparent. I don't use the waveform data type often so it isn't quite as obvious to me.

My MacBook Air can't see 5 Ghz "N" signal?

Any reason for this? My iMac can see it.
I've also posted in another forum that while connecting to my AEBS via the 2.4 Ghz signal, my MBA is not achieving download speeds nearly comparable to my desktop iMac (connecting my iMac wirelessly to the AEBS).
The networking settings are the same for both machines, but my MBA is slogging with download speeds, which are reporting to be slower (by a factor of 2x) than my upload speeds (my iMac speeds are much faster and near parity on the up-and down-load rates).
I'm connecting to the internet via Comcast 50 service, which is connecting to a Linksys WRT610n router. The AEBS is connected via ethernet.
Any thoughts??

Welcome to the discussions!
A few thoughts...
The higher frequency 5 GHz signals are absorbed by walls and any obstructions much more quickly than 2.4 GHz signals, so that may be a contributing factor in the question about not being able to "see" the 5 GHz signal.
If the MBA and iMac are in similar locations, the information in your post indicates that the wireless card in your MBA may not be performing up to par. This may or may not be related to the 5 GHz problem.
I assume you've done the standard things like restarting the router, your computer, deleting your computer wireless connection and password in Keychain Access and then establishing another connection, correct?

HT1218 2.4 GHz wireless signal not working has disappeared

I have a Time Capsule running the firmware version 7.6.1 (the latest) and today for some reason the 2.4 GHz wireless signal stops works and disappears (the signal no longer appears in the list of available netowrks on my iMac or iOS devices). The 5GHz signal remains and does just fine. When I cycle the power on the TC with about 30 sec downtime before powering back on the 2.4 GHz signal comes up just fine; however, after about a half hour to an hour the wireless signal disappears again . I have seen posts on the net that suggest renaming the wireless channels and changing the channel. Will try these but this seems to me to be a bit of a bandaid - while this may help I'd like to know why this is happening so I can perhaps take other actions to prevent it in the future.
Any help will be greatly appreciated.

Airport Express extends 5 Ghz and 2.4 Ghz or just one at a time?

I recently switched my dual band Time Capsule to use different names for the 5 Ghz and 2.4 Ghz networks.
Will the Airport Express extend both or just one at a time, if so, which one will it extend?
I have two Airport Express modules, bought a long time apart, is there any difference in functionality and how do I tell them apart if this is the case?
All are running the most recent firmware version.

Welcome to the discussion area, Mike!
Will the Airport Express extend both or just one at a time, if so, which one will it extend?
The AirPort Express is a single band device, so it can extend either the 2.4 GHz or 5 GHz band, +but not both at the same time+. Since you have different names for the 5 GHz and 2.4 GHz bands, the Express will extend the 2.4 GHz band by default. Using AirPort Utility, the setup application for the AirPorts, it is possible to configure the AirPort Express to extend either band.
If you are perhaps thinking of extending the 5 GHz band, this can be a bit tricky because 5 GHZ signals do not travel effectively over distance or penetrate obstructions as well as 2.4 GHz signals. You almost have to have a line-of-sight relationship between the Time Capsule and the AirPort Express to be able to extend the 5 GHz band.
I have two Airport Express modules, bought a long time apart, is there any difference in functionality and how do I tell them apart if this is the case?
Look on the side of the AirPort Express for the model number in the small print. You'll need Model No A 1264 to be able to "extend". If you have the older Model No A 1084, that version will not be able to "extend" a wireless network, but you could use it to "join" the wireless network and stream AirTunes to the device.
All are running the most recent firmware version.
That would be 7.5.2. If you have the older version of the AirPort Express, the latest firmware version for that device would be 6.3.

When I switch my time capsule to 5.0ghz mode the range of my wireless network drops significantly. Near the Time Capsule my Macbook Pro works fine, in my bedroom I have almost no signal. In mixed mode it works fine. Any ideas on how to get 5.0 working?

Thanks, W

I'm not sure if you understand that 5 GHz has some upsides, but also some very significant downsides.
The upside is that the 5 GHz signal will allow faster speeds.
The downside is that you must always give up something in order to gain something else.Unfortunately, the marketing hype about 5 GHz does not go into very many details about this.
In the case of 5 GHz, the 5 GHz signals are much weaker than 2.4 GHz signals, so they do not travel as far or penetrate any obstructions like walls or ceilings nearly as well as 2.4 GHz signals. In many cases, in order to get good 5 Ghz performance, you literally have to have almost a line-of-sight relationship between your computer and the wireless router.
If you have a new dual band router, which broadcasts both a 2.4 GHz and 5 GHz signal simutaneously, your Mac will connect to the best signal quality automatically depending on its location in relation to the router. In the same room, without any obstructions, it will connec to 5 GHz. But, take the laptop down the hall a few rooms and around the corner and the Mac will connect to the 2.4 GHz signal because at that location, the 2.4 GHz signal is not only stronger, it is also faster.

Why is my 2.4 GHz network 2.5X faster than my 5 GHz one?

When I got my dual band AEBS last year, i was thrilled to be able to take advantage of the 802.11n 5 GHz band. I'd read about folks getting ethernet thruput, and with my CAT5E connection, I can sustain around 9.5 MBps. That speed for wireless? I drooled uncontrollably.
I figured I'd get the old devices off the AEBS, so I set it up as 'N' only; the "G" band is serviced by my wireless FIOS router. I even went so far as create a 5 GHz SSID so I would be sure that I would connect to my new 5 GHz speed demon.
Well, after months and months of tinkering with my AEBS and throwing an AX into the mix, I've resigned myself to the fact that my 5 GHz network will always be maxed out at around 2 MBps, where my 2.4 GHz network's topping out at around 5 MBps, about 2.5X faster.
I must say, I'm disappointed. I've tried every channel in the 5 GHz band. Some - like channel 44 - give me 3 strength bars, which seems pretty good, since my AEBS is 2 rooms away. The 2.4 GHz band usually is 4 strength bars, so if I don't have separate band SSID's, my iMac will normally pick the 2.4 GHz band. But once in while, on channel 44, my iMac will pick 5 GHz. Of course, I know it immediately...stuttering video playback, iTunes taking forever to retrieve album info, copies between my iMac and ReadyNAS NV+ waiting an eternity even to start copying. I do the Opt-click on the Airport icon, and yes, I'm logged into my speedy 5 GHz network. Needless to say, I didn't leave 2.4 GHz and 5 GHz bands combined very long. I've assigned separate SSID's to each frequency, and always make sure that I'm on the fast 2.4 GHz band.
Now, I don't think I'm stupid, but for the life of me, I can't figure out why my 5 GHz band seems to be maxed out at around 2 MBps. At least it seems that way, since I've never seen anything sustainable over that (maybe a peak at 2.1 MBps). The 2.4 GHz band easily stays consistently around 4.8-5.0 MBps. This speed difference is very noticeable, and can easily be seen from my iStat Menu's Network display.
I've even tried extending the 5 GHz band with my AE, and although the Transmit Rate gets to around 200-300, the real life speed is still slow as molasses. So I gave up on extending the network, and just use the AX for AirTunes.
Here's a look at my 2.4 GHz stats:
Notice that there's also a DigitalBirdie (5 GHz) network. That one's 3 strength bars, not too bad. Now for the stats on that one:
The Transmit Rate is low at 41, half the 2.4 GHz band. But I've had Transmit Rates in the 200's and it's not made much difference in thruput, if any.
Changing to the 5 GHz channel always leads to thruput slowdowns, but some are far worse than others (like file copies taking many seconds to start). But at their best, they never get better than around 2 MBps, even if the signal is fairly strong. I'm thinking I must have some configuration problem somewhere, but I can't figure it out. I've been banging my head trying all possible combinations to see if I can get over this 2 MBps hump, but I can't do it. I'm stumped.
Does anyone have an idea what else I can try? I'll do anything at this point, other than running 75 feet of CAT5E and ditching Airport
Thanks.

Hi Bob,
That's the strange thing. When I had both GHz channels working on one SSID, once in a while my iMAC would pick the 5 GHz channel (44 seems the best for me). I always use channel 1 for 2.4 GHz because I get the fastest speeds with it.
When the iMac would pick 5 GHz, the slowdown was very obvious. As I explained in my (long) first post, I immediately felt the difference. Now the $50K question - since the 5 GHz channel at that point was stronger than the 2.4 GHz one, why wasn't the speed faster? Why was it so slow compared to 2.4 GHz? That's what rattling my brain. If the 5 GHz signal's strong enough to get picked by my iMac, then why isn't there a commensurate speed increase? There must be something else going on here besides signal strength. If the 5 GHz spec says that I must have full strength to get 5 GHz speeds, then that makes sense. But I think it doesn't, that's why I believe I have a configuration problem somewhere, or a faulty AEBS.
I might add that my firmware's up-to-date in the AEBS and AX, and Airport Utility too.
I think heading to 4Runner's camp - even with high signal strength (and I would consider 3 of 4 bars high), the 5 GHz speeds aren't showing themselves.
Here's some snap's of my AEBX's setup:
I think my configuration's fine, although I've tried so many different options, I'm a little confused, but I know that changing the Multicast Rate doesn't have any noticeable effect on the speed. I also have "Use Wide Channels" checked, but as I said, the 5 GHz band is awfully slow for using both channels. I have set "N" only, so no "G" clients to slow it down.
Mind boggling!

Airport express different names for 2.4 GHz and 5.0 GHz channels??

I have a airport express router and I recently purchased a smart bluray player. When I try to connect my bluray player to my wireless network it shows both the 2.4 and 5 GHz channels which have the same SSID. I select the 5 GHz channel, connect to it and after connected it shows that I'm connected to the 2.4 GHz channel and my bluray player tells me that it would work better on a 5 GHz network. Is there anyway to give each channel a different name/SSID so that I can definitely only connect to the 5 GHz channel???

Is there anyway to give each channel a different name/SSID so that I can definitely only connect to the 5 GHz channel???
Yes, assuming that you are running the Lion or Mountain Lion operating system on your Mac.....
Open Macintosh HD > Applications > Utilities > AirPort Utiliity
Click on the AirPort Express icon, then click Edit
Click the Wireless tab at the top of the window
Click the Wireless Options button near the bottom of the window
Enter a check mark next to 5 GHz name and this will assign the same SSID with "5 GHz" added the name.
Click Save, then click Update and allow a full minute for the AirPort Express to restart
However.....unless the Blu-Ray player is quite close the AirPort Express, or it has direct line of sight with the AirPort Express, the 2.4 GHz band will likely provide both a stronger and faster signal.
If the Blu-Ray player is connecting at 2.4 GHz now, it is probably thinking that 2.4 GHz is the stronger and also possibly faster signal.
This is because 5 GHz signals are much weaker than 2.4 GHz signals, and as a result, the 5 GHz signals are absorbed much more quickly by any obstructions like walls, ceilings, or heavy furniture, etc. in the signal path.
The bottom line....connecting at 5 GHz does not necessarily provide a better connection....but you can give it try to see if you notice any improvement.
If you don't mind spending 4-5 dollars for a good WiFI utility like WiFi Explorer, which will display the actual Signal to Noise ratio of the wireless signal, and you want to go at this a bit more scientifically, post back for more info.

HT1365 Why is my iPhone 4 running so slow? It will be connected to a secure wifi signal, with all the bars yet still say its unable to connect to the Internet. Plus, Internet aside, the phone overall is acting very unusual. Moving very slow.

My phone is running so slow in every possible way, on the Internet or not. My apps are constantly crashing and I never used to have this issue before. Typing a text is absolute Chaos! I have turned EVERYTHING on and off. I have cleared out my running apps menu, history and cookies. I have even gone through it and deleted unwanted photos, videos and apps. If I lived closer to an Apple store I would just take it in as I have AppleCare. But I am over an hour away from the closest location.

WRT600N Wireless n 5Ghz range much less than the second channel 2.4 Ghz

I just bought the WRT600N a few days back and have finally got it working so that all my devices (mac mini wireless g, i2eye Phone wireless g, thinkpad wireless b, etc... and Mac book pro wireless n, apple tv wireless n etc...) connect well and are working well from a close range. I went thru some of the same discoveries as some on this forum went thru. The 2.4 Ghz was the most annoying. I had to manually set the channel to 6 to get a number of devices to connect. That was after quite a bit of frustrating debugging.
My current setup:
All SSID's are set to specific names Use Mac Filtering without any security.
The 5Ghz channel is set for Wireless n mode only (Would like to get a dedicated 300 MB/s connection for the n devices. That is why I bought the dual channel router)
All other settings are default
I see it set on Wide channel 40MHz channel 38
Standard channel 36
broadcast enabled
The 2.4Ghz is set in mixed mode
It is set to Standard 20Mhz with a fixed channel 6
broadcast enabled
The problem I am having is as I go into my bedroom upstairs or in my basement the Wireless n 5Ghz channel is at best flaky and either the signal is dead or I get dropped connections. In many cases you can't even see the SSID. On the other hand the 2.4 Ghz signal works from all these locations fine and with even the furthest points in the house getting atleast 3 bars out of 5. However, many of these far devices are being used for streaming video and the b or g network is unacceptable.
I used to have a dlink mimio router and the b g network from that was as strong if not better. It goes without saying that I have scanned the forum for all possible suggestions.
The firmwares are the latest and greatest and the router now is sitting on top of a book case that gives it a good height and visibility. It however is in one corner of the house and I don't have a choice there. Fundamentally the problem is that the wireless n is not working from the same places the wireless g signals are strong?? I have played with changing the settings on the 5 GHz channel but nothing seems to work. My apple tv in the basement can't even see the wireless n ssid?? while the wireless g has almost full strength. That said when you are within a certain distance of the router the wireless n works well and is great. So it is clearly a range issue??
If I don't hear from anyone this one is certainly going back...
Thanks, MM

There is no channel 161 for the Linksys's N portion. If you choose Wideband, it offers you 3 choices... Auto(DFS), channel 38 or channel 46 and that's it.

I have a WRT610n and the 2.4 GHz just stopped working (5 GHz network is working fine)

Almost with the coming of the new year, the 2.4 GHZ net slowed down to nearly nothing.
That is to say that it works only very slightly, and is usually not even visible as an option to select.
But the 5 GHz network is available and works fine.
Here is my setup:
Speed touch modem supplied by Telus
Linksys router WRT610n ( i think version 1, because there is nothing written to tell me otherwise - there is no ver 2 next to the model number)
Macbook Pro laptop (new)
dell windows laptop (old)
two pc desktop machines (one running 2.4 GHz wireless net adapter, the other running a 5GHz net adaptor)
an iPhone (new) --> only works at 2.4 GHz (i checked)
the wireless networks are named as follows:
"SHONESY 5 GHZ" for the 5 GHz signal
"SHONESY 2.4 GHz" for the 2.4 GHz signal
for months, everything worked fine. the macbook communicated on the 5 Ghz net along with one pc downstairs (wirelessly).,
my iPhone communicated nicely with a full strength signal and good speed.
then, something changed and the 2.4 GHz net all but failed.
when the dell is plugged in via a hard line ethernet cable to the router, no problems - i get 1.3 MBPS on the speed test
the macbook can only see the 5 GHz network, but works fine.
same for the pc downstairs that runs on a 5GHz wireless network USB adapter
the iPhone now only gets one bar (if anything at all), and usually cannot connect (but can usually see the SHONESY 2.4GHz network in the utilities/wifi setup area)
i am really stumped.
could the router have failed? how can i check it?
what could explain what I am seeing.
Thanks in advance for any help you can provide.

Try resetting the device by holding down the reset button on the rear of the device for 30 seconds. If this does not resolve your issue, then it may be a hardware malfuntion. I have noticed that my 610n was running very hot and it was a common problem so I put a laptop cooler under it and its been keeping it nice and cool. May have just burned out. I hope you get it working.

Setting up a 5 GHz only network with my AirPort Extreme

"I recently purchased a 21.5" Samsung monitor that is connected to my late 2009 13" 2.26GHz 8GB RAM MacBook Pro through a VGA connection with the VGA to Mini DisplayPort adaptor. Since I've started using it, my Internet connection has slowed to a crawl. I've researched the issue online and external monitors can apparently created wireless interference. I'm using a 2011 AirPort Extreme 802.11n/b/g. Is there anything I can do to eliminate this interference?"
I posted this at this link https://discussions.apple.com/message/18254901?ac_cid=142432#18254901?ac_cid=142 432 and did receive an informative reply that led me to believe that my monitor currently broadcasts in the same wireless band that my MacBook Pro is reading on, in this case 2.4 GHz. I know the AirPort Extreme broadcasts in a 5 GHz band as well (which I thought I was, on all this time) and would prefer that my MBP read from that wave instead anyway (which should in turn solve my problem). I looked up how to do this and was told that by using AirPort Utility (version 6.0), and check to uniquely name the 5 GHz network, a separate 5 GHz only network should be created and selectabel under the Wi-Fi menu in the menu bar. I check this and restarted the router, but did not see the new network for the same router. I need to be able to force my MBP to read on the 5 GHz network since the 2.4 GHz network currently slows my internet connection to a crawl. Any advice on how to properly do this?

Something is amiss here.
Normally, if you enable the option to assign a separate name to the 5 GHz network, AirPort Utility simply adds 5 GHz to the name of your wireless network.
So, if your normal network is named......
Wireless Network, when you enable the 5 GHz option, another network is created with the name Wireless Network 5 GHz.
Once the AirPort Extreme is updated, you must click on the fan shaped AirPort icon at the top of the MBP screen, click Join Other Network, click Show Networks, and then select Wireless Network 5 GHz and enter the password to connect.
This action "points" the MBP to the 5 GHz network that you have named.
Next, you need to change the settings in AirPort Preferences to make sure that the 5 GHz network is located first at the top of the connection list....so the MBP will connect to the named network first, and automatically.
Unfortunately, "forcing" a Mac to connect to 5 GHz will not necessarily result in a better connecton if there are obstructions in the signal path between the Mac and AirPort Exteme. 5 GHz signals are significantly weaker than 2.4 GHz sigals, so they will not penetrate walls, ceilings and other obstructions nearly as effectively as 2.4 GHz signals.
Post back to tell us what steps you are performing now.....and what happens after each step so we can sort things out to see if 5 GHz will result in a better connection.

The Fios Gateway 5 GHz Wireless radio is unstable. This is my second Fios Gateway router and I'm having the same problem. The 5 GHz signal is very weak. There a spots where the signal is unavailable yet the 2.4 GHz. I even installed aWi-Fi range extender (the one Verizon sells) but the signal did not improve I'm thinking that the Fios Gateway Wi-Fi radios are crap. I think the best way to proceed is to buy a solid wireless router and shutoff the Fios Gateway wireless radios. Can anyone recommend a wireless router with a usable 5 GHz radio? I think a commercial Wi-Fi router is the best way to go. Thank you. I have tried to get Verizon to come out and check my Verizon equipment but that is impossible. Notice that when you make an service appointment, Verizon calls every morning and if you don't push the right button, they CANCEL your service call. This is something Congress needs to legislate - SERVICE. I'm thinking of going back to Comcast.

I have a WiFi extender in line of sight of the Fios Gateway router and the 5GHz channel is still unstable. At this point I have to assume I can't use the 5GHz channel so I will return the Fios Gateway router rather than pay the monthly fee for an inferior router. This router is slow even for wired access. For whatever reason the Fios Gateway routers are not compatible with my Verizon equipment. My ActionTec is faster and more reliable. I will also get the most powerful 2.4GHz wireless router and use that as a separate wireless access point instead of the wireless radios in the Verizon routers. I can't imagine busineses putting up with these problems when it comes to 5GHz channels. Thanks.Ed
