Hey, I currently have 50 Mbps internet through cox. Recently my roommate has started watching anime tv shows on a streaming site, it will only be him and I using the wifi internet and it will be super laggy while playing video games for me. I was wondering if this is normal... I would think I shouldn't have any problems with lag having 50 Mbps internet, with it being only two people using the wifi also... Is there any way to fix this problem or maybe I should try replacing the modem?
 
Solution
Dont buy a combo modem router.
Change service type (to DSL or Fiber) since you have a combo now you need a new modem and router
Internet speeds above capability of modem...need a new modem and router
New better faster wifi standarad......your guessed it, need a new modem and router
Modem part stops working like it is supposed to.....need a new modem and router.

For these reason's alone separate devices are better. Besides needing an extra power outlet and ethernet cable there is no "inconvenience" from the separate devices.

This modem wil support up to about 200mbps real world speed: https://www.amazon.com/Zoom-5345-Certified-Spectrum-Providers/dp/B013C4L6OE

I have been suggesting this router. It is an Asus RT-AC68U (retail $150)...
Depends on what bitrate/resolution the anime is in. If roommate is taking 5mbps bandwidth for the anime then no big deal, if taking 15-20 then yeah thats a big deal.

If possible at least one of you should be on wired ethernet which will just make your ijnternet/modem the limiting factor and not wireless radios

Perhaps look at your router. Does it have dual 2.4 Ghz/5Ghz capability? If it's only at the 2.4Ghz range, tons of other devices are using that bandwidth, which drags down the ability to stream...internet bandwidth isn't the only issue.

I would suggest replacing the router for that dual capability. The Netgear Nighthawk AC1900 (Model R7000-100NAS), for example, has been getting some good reviews and is in the $160 range.
 


Speed will depend on how many others around you are using WiFi. (The more people, even if on different networks, will congest WiFi signals, especially if on the same channel or those in close proximity.) Look for a channel that has the least amount of networks on it AND as best as possible, adjoining channels that have the fewest networks on them. If they are on the same or adjoining channels, the weaker their network signal to yours, the better.

The type of Wi-Fi you're using will make a difference too.... Wireless AC being the fastest and wireless B being the slowest (AC, N, G, B, A) You'll feel it more the slower your own WiFi (which is independent of your speed coming into your cable or DSL modem, (Cable in this case.)

Distance to the wireless router will have an effect too... try to keep the router centralized for the best even coverage.

Those things should help some anyway. Forgive me if you already have tried any of this.

It should be better, yes...from everthing I've read, a router such as this will detect if the 2.4 Ghz band is a little too clogged and switch to the higher 5 Ghz band. Think of the 2.4 as a slow interstate jammed with traffic and the 5 a frontage road where much less traffic might be...the interstate moves slow with so many drivers on it but the frontage road has fewer drivers so the cars can move a lot faster. If the 2.4 Ghz lanes (main interstate) is jammed up, the modem will automatically shift to the 5Ghz (frontage road) lanes to move traffic with less interference.

That said, I'd maybe call Netgear to verify if using an external router would be OK since your modem has a wi-fi router built in...since both are Netgear products I would think they would know if there's something technical that would interfere with operation or not.

The answer Boosted provided is also a good one, and cheaper at that. If you're dead set on using wi-fi, explore the upgraded router. If you're flexible, run a couple of Cat-5 ethernet cords to each computer...the latter would cost a lot less and would give you both much faster bandwidth, as the hard line connection is still the fastest way to get bandwidth.

Hope it helps, and good luck!
 


No, a router does not switch from one band to another. A router just runs both bands independently and really does not care if one band has 12 devices and the other has 2. A decent router will switch channels on the 2.4 band to find the least congested channel (not congested by your wifi devices but by nieghbor's wifi router.



Both bands are like interstates. If anything the 5ghz band is the faster one with new AC routers having over 1gbps (theoretical max) speed on 5ghz band and much slower on 2.4 band. The 2.4 band only has 11 channels and out of those 11 channels only 3 are non-overlapping. Anything faster then N150 requires the use of 2 bands so in any suburbian neighborhood or even worse apparmtnet building you are going ot have many many wifi routers all trying to use the same channels and thus causing interference.
The 5ghz band has many many more channels and their frequencies are spaced farther apart so they have much less interference. The other key to 5ghz which is both a pro and a con is that a 5ghz radio signal is going to be less able to penetrate objects (like walls) thus you wont get interference from neighbors but on the other hand it also means that you wont have a good 5ghz wifi connection if that signal has to pass through 3-4 walls.



After doing some research it seems that your modem specifically is a little fishy in regards to dissabling NAT (often refered to as bridged mode) in order to have it act as a modem only and not have 2 routers (having a router and your modem/router as a router will not help you in any way).

My advice would be to get a new modem and router and never buy another combo device again.
If you have 150mbps or slower then a zoom 5345 is a decent modem for comcast or spectrum.

I have been suggesting this router. It is an Asus RT-AC68U (retail $150) for only $80 it just has some Tmobile branding and mildly modified firmware but the radio and the cpu and all the internals are the EXACT same as the $150 model.

EDITED:
Posting the link to router would probably help: https://www.amazon.com/T-Mobile-Wireless-AC1900-Dual-Band-AiProtection-Complete/dp/B01MYTAURW

ok cool, so if i get those two items you listed, that will give me the 5ghz wifi speed ive been wanting and i will be able to return the rental right?

Also last question sorry to keep this going but I'm running into a problem with my wifi adapter it keeps overheating and turns off my wifi, i read a post that the usb wifi adapters do that a lot. i was wondering if you had a good usb wifi adapter to recommend me that is able to connect to 5ghz wifi and possibly better then my current wifi card which overheats after 20 mins of use....?
