I am not super knowledgeable in computer networking but I am a hobbyist that often tries to fix stuff for the small business I work for. Generally I do alright but right now I am stumped. We require a static IP for a couple websites to work for us and we decided to switch out routers. I set up the first router without a problem and it worked for a couple years. We are using a linksys 2500 wireless router with the wireless disabled. I have the static configured the same exact way as the other one but periodically, the computers external ip address shows up as the gateway and not the static ip so we can't access the restricted websites. After we reset the modem and router, everything will work normally again for a day or two then we have to repeat it. Any help would be greatly appreciated!
Static IP Issue

Solution
The router is a linksys BEFSR41 Ver 3.1.
Modem is Ubee DDW365.
We were assigned the static by our cable company
I also forgot to mention that we have security cameras installed and I have dmz enabled to that internal ip address so we can access them from other stores. With the old router, they were losing internet connection pretty often the past couple months so I decided to put in a router I was using a few months ago to see if that would fix the connectivity issues. They haven't lost internet but now this new problem came out. We have Charter internet and we contacted them first but every test they did showed that the modem hasn't lost connection in the couple months they went back.

That's gonna be an on-going problem, often you can put stuff "together" but without enough knowledge of why things work, when problems happen, you can't explain it, hence can't fix them.
You are trying to throw us too many pieces, am gonna wager nobody here will have enough time to do a full analysis of your network. However you can certainly narrow down to a couple of specific issues, and tell us what have you done so far to troubleshoot it and perhaps we can make a breakthrough.
Well, I mentioned pretty much everything I did. I was really hoping it would just be a setting I missed somewhere or someone could possibly point to faulty hardware. I definitely have experience but I wouldn't claim to be an expert. Basically, all I did was install the router, configure the static IP address, and test the secured websites we need to access. There hasn't been much troubleshooting. With DMZ being enabled for the security cameras, I was wondering if there could be some kind of conflict but that seems weird because we didn't have this problem before and I haven't had trouble at the other two stores I set up. The problem is that the external ip address is showing up as the default gateway and not the assigned static ip. I also do not work at the store I am trying to troubleshoot so that makes it more difficult.

You'll need to elaborate a bit more about the exact configuration of your network.
The Ubee modem is actually a gateway (i.e. modem/router). Plus you mention 2 Linksys routers.
Having more than one router on your network will cause problems if not configured correctly.
What device are you trying to configure with the static IP address? Were you provided 1 static IP or a block of IPs?
I replaced the linksys BEFSR4 with linksys 2500. So it is the Ubee DDW365 that then connects to the linksys 2500 and then to the computers and security cameras. The Ubee is what Charter gave us. External comes up as the static initially, but when the employees come in the next day, the external comes up as the default gateway and access to the website is denied. Once they reset the router and gateway, it works properly for the day, then goes back to the default gateway. That's the part I am not understanding. Also, I believe we have 2 static ips, only one is in use.

So it is Ubee --> Linksys --> PCs and cams?
Is the static IP configured on the Ubee or a different device? Just trying to get a clear picture of where exactly the default gateway IP is replacing your configured static IP address.

Since you wish to configure the Linksys with the public static IP address, you'll need to put the Ubee in bridge mode.
Not sure how it is managing to work currently, but there is most certainly an IP conflict if both the Ubee and Linksys have a public IP assigned. Also, the Linksys' WAN facing address should not be changing if it is set with a static IP.
I find it very odd that the Ubee can't be configured with a static IP. If this is the only reason you need the Linksys attached, I would highly recommend contacting your provider in getting this resolved.
The bottom line would be to have only one NAT device on your network: either the Ubee or the Linksys.
The ubee isn't assigned an IP address. It basically just acts like a modem. There is no page to configure the ubee. When I contacted Charter to configure the static ips, they told me I would need a router to have more than one pc behind the static otherwise I could only assign one computer the static ip.
Edited part
After thinking about it, it wouldn't be the first time tech support was wrong about something so I am definitely going to test it out. Charter did say the ubee had no ip and it was just a modem but it does seem like they could be wrong. Would explain why their internet was really spotty before too before I switched out routers. I did see some posts in other forums though that says that charter business locks out the page and it is installed in bridge mode. I guess we will find out!

That could be right about Charter installing in bridge mode, and likely true for a business install. It's just strange that your static IP gets replaced by a "default gateway" IP, which I'm assuming is a private IP address.
A static WAN IP configured on the Linksys should not be changing, and a private IP should not be assigned by the Ubee when in bridge mode.
The only thing I can suggest is to make sure you have the latest firmware for the Linksys. I would also recommend double checking the requirements for a static IP from your provider. You might need to make sure that the IP has to be manually configured.
