Apartment Internet With No Modem?

I share an apartment with 3 other friends. We've been here for a couple months now and I'm still trying to figure out the best way to set up our home network. Sorry for the long post, it kind of just kept going.

This is the router that I purchased before moving in. I know it's not high end, but it was reviewed well and seemed like a solid choice. It seems to work fine as I think all of our issues stem from the way the internet in the apartment is wired/configured.
http://www.tp-link.com/en/products/details/cat-9_TL-WDR3500.html

Our Internet package is provided by WOW and is a default package that comes with our rent for the apartment. Speed seems to test at 25 down and 5 up on Ethernet. I have had no interaction with them and every apartment in the complex has them as their ISP since it's bundled with our rent cost. The apartment complex office said "just plug in a router" to get WiFi, so they're probably not much help for the problems I'm having. If I need to, I can contact WOW for support, but I'd prefer not to do that unless needed. The service out of the wall is actually pretty good, but I haven't heard good things about their customer service.

There are 4 bedrooms, and each has an outlet with a CAT5 port and I assume a phone line port (too old for me :p). Plugging an Ethernet cable into the CAT5 gets us Internet in each room. Each room has a separate public IP address, but appears to share our bandwidth of 25 down/5 up. There's no way to see each other on the network from what I can tell as it just identifies it as a "Network" with an internet connection. There is also a 5th CAT5 plug in the living room that provides Internet as well. I currently have the router hooked up out there with just one plug from the wall and the power. There is no modem in the apartment, which seems to complicate things.

3 of the 4 rooms have desktops that are always wired in while the 4th room has a laptop that gets plugged in when needed. Our WiFi signal is pretty weak it seems and doesn't seem to cover the apartment very well. WiFi is used by 4 laptops (rarely all in use) 4 smartphones, and a few consoles. It's only ever really utilized by one laptop or the Xbox very much and works well enough for that.

Known Quirks/Problems
- Having the 5GHz band enabled on the router makes the 2.4GHz band simply not load anything, but still appear as a functioning connection otherwise. Speedtests will seep by a few tenths of a MB. Restarts of the router sometimes will fix this temporarily, but might also cause the next issue.
- DNS Probe Not Finished is a common error that would be found on both the WiFi (multiple devices at once), and/or one or more of the wired connections. Acting as if it couldn't handle having that many connections all at once. This was only really a problem when the 5GHz band was on. I've had it off for most of our stay and it seems to alleviate most issues. Random drops of one port or the entire WiFi network still happen, but rarely. I wonder if moving the router to a bedroom and cloning the IP would alleviate this. I don't know really even what that means, but have read a little on that helping with stuff like this.
- Through the wired connections, there doesn't seem to be anything controlling bandwidth. 2 of my roommates play LoL religiously and it seems that any download on another wired connection will completely lag them out of the game and essentially make their internet useless. If I run a speedtest, it "gives" me all of our internet speed, and the other computers are horrendously slow at loading anything until it's done. We're all PC gamers, so this is a big annoyance. I have noticed though that if I'm just streaming Netflix or downloading something that is throttled below our usual max speed, it doesn't affect them noticeably. If the only bottleneck is our internet speed, it will give all of our 25mbps speed to a download though, and ruin the rest of the network rather than throttle me slightly to keep the rest afloat.
- WiFi coverage is pretty terrible. Probably has mostly to do with placement/interference. The back two rooms have pretty unusable WiFi signal and the front two are spotty. Given how small the place is, that's pretty bad.
- My printer, Canon MG6220, doesn't seem to want to connect with my router. It worked fine on different networks. Probably a result of funky configuration.

Ideal Goal
- WiFi coverage for the 4 bedrooms and living room.
- Better bandwidth allocation on wired networks, if even possible. This is really an annoyance, but very well might not be possible.
- 5GHz band back on and functioning. This isn't a huge priority, but would be nice as our smartphones could make use of it
- Wireless printing would be a perk, but not imperative. I'd imagine fixing the network setup would solve this too.

In all honesty, I should probably just call the ISP and see how they have this stuff set up, but I kind of want to figure it out and learn for myself. I'm sorta lost when it comes to networking beyond "turn it off and on again". Thanks for any help. :D

I attached a layout of the floorplan, if it matters. The router currently sits on the kitchen table. It's not great placement, but the port out there is under the table. I have a long Ethernet cable I could get creative with if needed. Even the WiFi in rooms closer to the living room isn't great.

Can you see other local hosts if you explicitly allow the others on Windows Firewall?
You could also ping from a directly-connected host to another one and see if you can see their NIC's MAC in ARP since you should be on the same subnet. What kind of mask does it give with the public IP?

C:\Users\tbeers>arp -a

Interface: 10.111.52.4 --- 0xb
Internet Address Physical Address Type
10.111.52.1 00-00-0c-9f-f2-14 dynamic
10.111.52.2 54-7f-ee-b5-0e-bc dynamic

Basically we're just trying to see the upstream end topology, most shared environments will just put an entire building on the same VLAN and hand out public addresses, but there's no ACL or segmentation between hosts, although you'll a lot of times see things like Windows auto firewall against other public addresses.

Do you all have to put in the same account information when you connected each PC? It might be managed via a bandwidth management platform on an account basis.
 
So many acronyms I have to learn! :p

I can't decipher much of this really, but it looks like a lot of static stuff...

There's no login of any kind. We have no interaction with the ISP and it's essentially plug and play. We get a basic package for cable and internet included in our rent cost and if we want faster speeds or more channels we could pay more for that. The only other bill we have is electric as all of our utilities and what not are included. Nice, but doesn't give you much flexibility in terms of this kind of thing.

I'll have to do some more in depth digging when I have access to their computers. The LoL duo has a tournament this weekend and I'm basically forbidden from doing anything that could interfere. :D I remember a month or so back at your suggestion finding out if they had public IP's. Apart from that I don't have much up to date info with how their connections have been "Some lag spikes" is all I ever get from them when asking.
 
I moved the router to my room now. It plugs into the wall in here and my computer is wired from the router. Both 2.4GHz and 5GHz channels work so far. 2.4GHz channel also does a better Speedtest than it used to. I think it was just a whole lot of interference causing that slowness and the MAC cloning probably helped with the random drops on different connections. Hopefully it lasts.

Now if I could just get it to control the bandwidth... on the wired connections.
 
Can you post a screenshot of the wireless networks in your area? I'd download "WiFi Analyzer" in the Android play store, and take a screenshot of the 2.4 and 5GHz bands. Why did you clone the MAC? I'm not sure what the reasoning was behind that. Usually that's what you do if your ISP requires the MAC address of the connected device.

Are you opposed to running cables around your apartment? I'd recommend two AP's personally as that's a large apartment. You could also run each of your desktops to your router, and then perform QoS and priority on your end which will help when one of you are downloading, but obviously won't help when other apartments use the network.
 
I've used WiFi analyzer and the congestion is insane. My room is on the edge of the building and has way less interference than where the router used to be. I don't even have a competing router on the same channel.

I cloned the MAC because it was the recommendation by the router to do so. It works fine, but I haven't tried it without either. I'm not going to run wires and don't really want to spend more. The WiFi signal is much stronger now and the farthest room from mine still gets pretty good signal.

We never get lag issues unless it's one of us 4 using it, so other apartments usage doesn't seem to matter.
 
I don't even have a competing router on the same channel.
1, 6 or 11? :p

Keep in mind that at a 20 MHz (default) channel width, other channels in between those overlap and receive interference from other channels. Here's a diagram that kind of outlines it, if you see a neighbor that plops their wifi network onto channel 3 for example, punch them in the face since it interferes with the airspace of both ch1 and ch6 ;)

I'm on 11. There is no interference from where the router is broadcasting from, but if you go to the main room or the other 2 bedrooms, it'll have competing signals. Does the interference only matter from where it's broadcasting or also where it's receiving? My room has 4 signals, including mine, and mine is noticeably the strongest. Going to the living room and I now have about 12 signals, some of which are about equal in strength to our own. Signal in the farthest room is weaker than some other networks, but still pretty good and seems to be functional. Our 5GHz converage is much better too. Before it wouldn't even see it in the back rooms, now it's in the whole place.

I've got the router up against the side of my computer. Does the tower help amplify the signal at all? I've got the antennaes pushed up against it for good measure. :p
 
Interference matters everywhere you use wireless. It's great that the AP doesn't have co-channel interference from what you're saying, but the performance of your network in areas where there are multiple APs on the same channel will suffer.
 
Welp. Problem still is there. When my roommate that has just a laptop plugged into Ethernet with the rest of us plugged in and WiFi on, his signal wouldn't take. So, it still won't take 4 wired connections with a router using Dual Band. 4 wired connections with only 2.4GHz enabled still works pretty much fine. I'm going to contact the ISP and see if they can help me out. Any suggestions? I might try setting the 2.4GHz to b/g only and the 5GHz to N only.

What do you mean his signal wouldn't "take" when he's plugged into ethernet? Why would he need WiFi if he's directly connected?

Are you saying when you have 4 wired connections into your router, you can't use both 2.4GHz and 5GHz? Does just one work? If so, which one?

When you say it doesn't work, can you still utilize your LAN? I.e. access and ping other devices on your network?

This doesn't sound like an ISP problem at all, sounds like a malfunctioning or poor quality wireless router.
 
Read the OP again, but I'll try and clarify. There are 5 wall plugs of CAT5 that provide internet in the apartment. One in each bedroom (4), and the final one in the main living room. Previously I had all 4 bedrooms (3 desktops and 1 laptop) plugged into their own wall plug and received internet straight out of the wall. Each of these devices received a separate public IP address. There is no modem in the apartment and they had no relation or connection with the router. From what I can tell I can't even "see" them within the network from one computer to another.

The router itself was plugged into the 5th wall plug in the living room (also it's own public IP), and just provided WiFi for the house and didn't have anything plugged into it. When I had dual band on it would typically cause one of the wired machines to stop receiving internet. It would usually say DNS Probe Not Finished and sometimes just not load anything and other times have "Limited" connectivity. It also did this with each individual band, as in the 2.4GHz band would work (and all the wired machines too) and the 5GHz band would not, or the other way around. Sometimes both bands worked and one machine was out, although it seemed to favor dropping WiFi now I think about it. Disabling the 5GHz Band and just leaving the 2.4GHz alleviated the issue by and large. We'd still get occasional brief drops, but quite rarely and probably normal for an apartment complex.

Now the router is in my room and instead of my desktop being plugged into the wall, the router is plugged into the wall and the desktop into the router. I cloned the MAC address of my PC to the router when doing the setup, per the suggestion of the setup. The three desktops, including mine through the router, as well as both bands of WiFi worked flawlessly. No drops, no issues or anything. Then, the laptop user decided to finally plug his wired connection back in to his room wall plug rather than using the WiFi he'd been on since I moved the router. His laptop would not maintain a connection through Ethernet and said Default Gateway not available...

Oh man, I think I may have just figured it out. We reinstalled Windows 10 on his laptop and his Ethernet adapter driver may not be installed correctly.... I'll check that when he gets up. I totally didn't think of that being a factor. If that is the case, then derp. Still though, I'm mystified why having the connection setup as I do now works better than what I did before and what would cause drops like that.. Assuming the laptop is a nonissue.
 
I remember you saying that in the OP, but your last post made it sound like you were using your router and had clients hard wired into it.

I don't see how you enabling dual-band WiFi would cause a DNS probe issue, that just sounds like a wireless router problem. That's an interesting setup at your apartment though, and without knowing how it's configured from the wall to the ISP makes it tough to diagnose.

Either the manager of the apartment network or ISP would likely need to be involved.
 
I don't really understand the Dual Band thing either. I did just notice that the two separate bands have differing MAC addresses. They're identical except the last digit is off by one. The 5GHz band shares the MAC address that's listed under LAN, and the the 2.4GHz band is one value less than that. No idea if that matters or if it's supposed to be that way.

I got one the IPs of one of the other wired desktops. I pinged it on my desktop (and thus thru the router), and it didn't get anything. I don't know about the other two, but his IP and my IP's have been the same with our wired connections since we moved in. I'm fairly certain on that, but not completely. :p
 
Well, nothing has changed I guess. Laptop user indeed did not have Ethernet drivers working. When he did get hooked up though, the 2.4GHz channel dropped. So... I don't even know what to try anymore outside of contacting ISP. Tried disabling DHCP in the thought that there's a router(?) above me in the network that's controlling it. No cigar. Currently set the 2.4GHz to b/g mixed from b/g/n mixed and set the 5GHz to n only. Probably doesn't matter, but I tried it.

It's really not a big deal if 5GHz doesn't work since only 3 of us on our smartphones could use it. Just kind of want it to. :D
