Typically, the IP addresses are assigned by your router using something called DHCP. Under this protocol, the addresses are not guaranteed to remain the same. My IP address changed following a power failure. However, there are other reasons why the IP address changes.... .
In this particular situation (the Uniden WiFi dongle), the WiFi dongle is being reset by the scanner (as a work-around for the WiFi dongle lockup problem) every few (about five) minutes. Further, when the WiFi dongle is reset and then requests an IP address, it DOES NOT request a renewal of the IP address it has previously held (as most other devices in the known universe do). Instead, it requests a "new" (in the sense of never having had one before) IP address. Typically, DHCP servers keep a record (by MAC address) of previously issued IP addresses, and reissue the same IP address in this case. However, there is no guarantee of this, as others have noted.

Again, as others have noted, most DHCP servers (including those in home routers) have the capability of issuing a specific IP address (that you assign) to specific devices by MAC address. Every device (over 25) in my home network (except for routers) is set to get an IP address from the DHCP servers, but the DHCP servers are configured to issue specific (static) IP addresses to almost all of them. I do this because it allows the management of IP addresses to all be in one place.

The 536 is on 24/7. The following is recurring (see log below) while just doing normal scanning:
  • The 536 screen stops showing the WiFi icon.
  • The dongle's light is on.
  • Checking it through the 536 menu shows "WiFi busy".
  • Wait about an hour, no change.
  • Unplug and replug the WiFi module:
  • The dongle comes back to life.

The exact same thing happened here but I rebooted the scanner for safe measure and connected up with Siren using the same IP address.

2015-03-22 - Note: This time I reset the WiFi router to see if that might have been a cause. The Uniden WiFi dongle remained "busy" until I unplugged and replugged it into the scanner.

Anyone having problems with the Wifi/Radio connection to the network needs to provide the router make, model (including hardware version) and firmware version. Information about battery back up is important here as well, need to know if the router, scanner or both are on some sort of battery back up.

There are SO many routers and router firmware versions out and it is almost impossible to sort any network issue without knowing something about the router/hardware/firmware and battery back up situation.

In short, you CANNOT purchase a router for less than about $75 and expect it to work. I have even had $200 routers that do not work. If I show up to a job site and there is a Netgear router connected to the network, I immediately throw it away and replace it. I refuse to use customer provided routers unless they meet my requirements. Customers that listen to me are happy, ones that don't usually have problems.

It has taken me years to find a small sample of routers/firmware that actually work. You cannot assume if you find a router in brand X that works, that all brand X routers will work. I have had some cases with brand X cheap routers are far more stable that brand X high prices routers and vise/versa.

I rarely venture beyond what I know that works, because EVERY time I try something new, it is nothing but headaches.

Just because everything else in the house may be working, does not immediately mean the scanner or dongle is bad if it does not stay connected.

I have a very robust router that "WORKS" and have had few obvious problems with my 536HP. I have not been actively streaming, but everytime I do or every time I put the IP address of the scanner in a web browser it is "there".

There are a few Ping programs that you can load on a local computer and ping your router, scanner and other network items to see if and when the scanner drops off the network and these programs often allow you to find a trend or narrow down a problem.

Note that the WiFi dongle lock-up is NOT the same as not being able to connect. The fact that Uniden's code is having the WiFi dongle reconnect (rather than renew) every five minutes is indicative of them recognizing there is a problem here.

I'm curious what router(s) you feel are acceptable. One of the thing that will make anyone feel the need to reboot a Cisco router is the Internet provider updating firmware in their hardware on their end. I have Brighthouse for Internet and when they push updates for our cable DVR, it wrecks our internet access. I stopped hosing my own email and web site here at home because of all the tinkering they do. I only have my scanner being hosted on my domain.

I have been doing home networking for a long time and I beat my head on the wall too many times.

One of the problems is the "Industry" keeps changing standards and adding features and the overall Wifi modulation and standards are evolving. I am a firm believer that I prefer not to be on the bleeding edge of progress.

Here is where I am today, there may be other products that work, but I have found something that works for me and I stick with it.

1. I REFUSE to use an combined cable modem/router. This configuration give the ISP access to the router for firmware updates and the support monkeys can "reset" your device. "Resetting" and "Power Cycling/Rebooting" are 2 VERY different things. "Reset" puts the device back to factory defaults which you ONLY want to do when rebuilding your network.

So I will actually purchase a standalone modem if needed to get away from the ISP combined boxes. This does mean at times you may have to upgrade as the ISP implements new technology for their network. But it is a small price to pay for keeping support monkeys out of "your" network.

2. Do not think you can walk into BestBuy, MicroCenter, RadioShack, Staples, Office Depot, Target, Walmart and buy a router and expect it to work!! Get this idea out of your head now. Also do not think you can find a reliable router for under $50, its not going to happen.

3. Router firmware is the headache for anyone. I find that FEW SOHO router manufactures can develop and deploy router firmware for the products they sell. I often use free Open Source router firmware and find it far more flexible and far superior to anything that the router vendors offer.

4. I have found at least to date, that some of the Linksys/Cisco boxes are good with 3rd party open source firmware and most of the Asus routers have been stable. But with any vendor, I find it takes 18 months after the box is release for the firmware/drivers to be stable. Case in point, Intel WiFi products never work out of the gate, wait 18 months for the 3rd-6th round driver and they may work as expected. Even with Asus I have had problems with stability, dropping connections and hangs, but far fewer than other vendors and usually they are faster to solve these issues.

5. This comment will get a lot of heat, but I do not care. I try to keep things simple. Wireless G has been around for a long time and works and I have kept WEP on most networks for Legacy reasons. But for faster wireless and the fact that some of the newer firmware will not even support WEP, I have moved some of the networks to WPA/WPA2. I use the KISS method for the most part. I am far less worried about someone hacking a WEP network than the Asians, Indians, Russians accessing my accounts elsewhere or Malware/Virus/Phishing on a local machine. WEP is the least of my worries.

6. As for hardware, it is not a bad idea to have a stable "test" box on hand to rule out/eliminate problems. Routers are cheap compared to man hours. I swap out "known good" boxes all the time to identify and resolve problems. Along with using "Ping" programs to isolate if the problem is "internal" or "external" to a network.

7. So my mainstay "rock" that I have been using for years is the Linksys WRT-54GL. This is the WRT-54G box that runs Linux and has larger flash memory and a better processor than the stripped down Version 2+ of these boxes. I then use DD-WRT firmware in these boxes and they are ROCK solid. No hangs, no drops, no power cycling, just MASSIVE Uptime. But due to wireless N and AC implementaion and so forth, on some networks I have moved to the Asus RT-66U for good luck. I have also used some of the newer and more advanced Asus units as well as some of the lower cost Asus boxes with limit problems, but I have had some issues with earlier firmware. So far to date, I have not reflashed any of the Asus boxes with 3rd party firmware. I had bricked a few early on and found it was just to big of a PITA to sort out and the Asus firmware for the most part has done a good job.

8. Netgear, as mention, I toss them in the trash like used diapers. I had a LOT of problems and bad experiences years ago with Netgear, stayed away for many years. Had a customer recently on a cable system that was convinced to upgrade to the latest/fastest service. They sent out a combo Netgear Modem/Router. The piece of trash was EXACTLY as I expected, nothing more than another dirty diaper. It took a lot of convincing to the end customer to move to a stand alone modem and just put their oil router back in place, this was about a year ago and there has been peace and harmony since!

9. Be careful with advanced features on any router. Often these features are not fully tested/vetted and can become a real nightmare. Things like Parental Controls and Scheduling I usually stay away from and tell people these things rarely work correctly.

10. When a wired option is available, I try to use it. I open use a wired option as a way to test or eliminate problems as well. Also I prefer static IP addressed for items that never leave the home for things like printers, NAS, Smart TV's, Thermostats, BluRays, Network Streaming devices and so forth. I put these addresses at the top of the address range outside for the DHCP window.

11. Wireless signal coverage, what can I say. This is a big PITA as well. Wireless coverage works better horizontally than vertically. Do not expect good wireless coverage in a home where the wireless router is in the basement and 2-3 floors above you expect good wireless coverage. I run CAT5 to the core of many houses and install a WAP on the main floor up high near the ceiling in many larger houses, often inside a main coat closet or panty. Some houses I deal with I need multiple WAP's to get good wireless coverage. Each wall with drywall on 2 sides can kill wireless signals quickly. Book cases and cabinets, large flat screen TV's, large SubZero type refrigerators, metal duct work inside walls and even Low E glass with metal vapor deposited on the glass can kill wireless signals. Even include leaky microwave ovens and other wireless things impacting networks to include neighbors wireless phones. I have seen and deal with it all.

Bottom line is you need to look carefully at how the network is set up, what equipment is being used, what the DHCP address range is, how many static IP addresses are implemented, how good and reliable is the wireless coverage and what items may even kill the WiFi network. Starting with a stable and reliable router or WAP and having a spare WiFi router to isolate or test with can save a lot of time and headaches..

Also understand what the term "Reboot or Power Cycle" means and how this is different than the term "Reset" which is used far too often and incorrectly. Pushing any button usually "Resets" the device to default settings and should only be performed when you plan on totally reconfiguring your network and you have a few spare hours on hand.

Think before you act, pay attention and observe. These are key traits are required with dealing with networks and troubleshooting.

As great as it is to have networking implemented in the 536HP, it is adds a lot more complexity and issues for the end user.

Good luck.

If you are planning on running your scanner full time on a wifi feed, you may want to consider running it on its own wifi router with its own ssid name.

Agreed.

Unless Uniden finds a way to simplify this for the basic user, Mabel is going to need to call in and pay for the Geek Squad. :)

EDIT: FTR - I don't own an iPhone and am awaiting the Android version of the APP (and hopefully some improvements to it). However, my wife was nice enough to let me use her iPhone for about an hour to see the app in action. I had no trouble getting it connected and running on my internal house wireless connection once I determined how to enter the IP address. She did mentioned to me that in the brief time I used the app, it really drained the battery down (but I thought I read somewhere that Uniden is aware of the problem and has or plans to address it).

Any constant use of the phone will drain the battery - especially if BT is enabled. Been that way long before the app was available, or even planned.

So, what you're saying is you're smarter than Mabel... :D

Dongle Replaced

Well 3 1/2 weeks ago I sent my DOA Dongle for a 1 way trip to Ft Worth. Yesterday a new replacement arrived. Invoice stating replacement for non working unit. Plugged in, turned scanner on, everything updated. Entered wifi info. Except for a tweek and a typo in no time I've got VLC audio. Haven't tried anything else yet. Also I'm a Droid. So we wait.....My point is you can have a bad dongle and I'm not the only one....

Great write-up covering most of the common home networking problems. One to add:

If you live in a condo/apartment or in a densely packed neighborhood and you're setting up wifi, you HAVE to customize your wifi channel selection to avoid interference. Most wifi devices default to one of three frequencies - 1, 6 or 11 (G). If you look at a sweep of most neighborhoods or condos you'll see 95% of the access points stacked up on those three channels. No good comes from that. Depending on how close you are to your neighbors you can end up with serious performance issues due to interference.

There's a great free smartphone app called "Wifi Analyzer" you can use to sniff out a clear channel. Just run the app and take a look at the graphic, then log into your router and set it to use a clear channel. Makes a huge difference particularly if you live in a condo/apartment like I do. Attached is a sample from my area - I'm on channel 4.

Hello,

The reason for using 1, 6, or 11 is this set of channels do not overlap. So in your example the 2 networks on 2 still get interference from the systems on 1. I would have chosen 11 as the interference would be at a lower level. On channel 4 you are getting stronger interfering signals from 1, 2, and 6.

Daveharpe -
Thanks for mentioning this. I downloaded the app and found myself in a bunch of layers in one network. I have used the suggested channel quality display to pick a better channel for this network and set it apart.

Actually, in the situation shown above, the best channels to use with the least interference would be 9 or 10.

You don't want to be on the "in-between" channels - it is better to actually share a channel with other "loud" neighbors because of the nature of the 802.11 system. Co channel users (those on the same channel) must coordinate their usage with each other and therefore will "talk" to each other to best "share resources" (bandwidth). Those signals that are on nearby but off-center channels get treated as random noise and therefore cannot be "negotiated with". This is why it is always recommended to stay on either 1, 6, or 11 in the US on the 2.4GHz band as those channels do not overlap the 802.11 bandwidth.

So, yes, sharing the channel with others means that your signals must negotiate with the other users on that channel BUT that is usually better than dealing with non-negotiable noise.
