I have a country house on the outskirts and the wifi signal is really weak, especially at night. I already tried changing routers but it's still the same. What other options do I have? Is it worth getting an external antenna or should I switch providers?
Weak signal at night suggests atmospheric or equipment interference, not just router range, so before spending on external antennas check if your provider actually has coverage in your area or if they offer alternative services like fixed wireless or satellite.
If coverage is decent but the signal is still weak, an external antenna does help, but also consider repositioning your router to a higher spot in the house, away from thick walls and appliances.
Before you spend money on antennas, it's worth checking with your provider to see if you actually get good coverage on your land or if they're just selling you a service that doesn't work well in rural areas 📡. The nighttime interference you mentioned could come from equipment in the area (transformers, irrigation systems) or atmospheric changes, not just your router, so move your equipment to a higher, more central spot in the house to rule that out first. A trick that works: if you can, ask your provider to come do a technical diagnosis at no cost before you change anything, because a lot of times the problem is in the line coming into your property, not the wifi itself. External antennas help a bit but they're not going to fix a bad connection from the start 🤷.
Don't spend money on an external antenna without doing a basic test first: place your router at the highest point in your house (ideally near a window) and measure the speed in different rooms at different times of day. If the signal is consistently weak even close to the router, the problem isn't range but the quality of the connection coming from your provider.
What's mentioned in the other answers about checking actual coverage makes total sense, but there's something more specific you can try first: change your WiFi channel. A lot of people in rural areas don't do this and routers come set to default saturated channels by factory. Download an app like WiFi Analyzer (there are free versions) and check which channels are least congested in your area. Adjusting it in your router settings takes five minutes and sometimes makes a real difference, especially with those nighttime drops you're describing.
If things still suck after that, then yeah consider switching providers or specifically ask if they have alternative connectivity options (fiber, 4G access point, satellite). External antennas can help if you have weak but stable signal, but if the problem is that there's just not enough connection reaching your land in the first place, the antenna is only going to slightly improve what's already insufficient.
I had a similar problem at my place and it turned out the router was in the kitchen, far from where I needed it most, so I moved it to a central, elevated spot and the coverage improved quite a bit. That said, that nighttime issue you're describing is weird if you only changed the router, because normally the signal doesn't fluctuate that much depending on the time of day unless there's interference from other equipment or your provider's having issues with their antenna. Before you invest in an external antenna, I'd say contact your provider to have them verify they're actually delivering the service you're paying for in your area, and in the meantime experiment by moving the router to different spots around the house, especially higher up. If it's still weak after that, then it's worth considering a directional antenna or switching providers if there's another option available in your area.
The nighttime problem doesn't have to be interference - a lot of times it's just that the router overheats after being on for hours and loses power, so try turning it off for 10-15 minutes each night before you use it heavily. Apart from what they already mentioned about router placement, it's worth checking if your provider offers signal boosters (extenders or repeaters) included in your contract, because some of them are reluctant to mention it but they have them there without charging extra.
The nighttime problem you're describing is odd if it's just a range issue, so my first suspicion is interference. Home routers use the 2.4 GHz band, which they share with microwaves, baby monitors, cordless phones, and tons of other stuff. At night there might be less environmental interference but more activity from equipment in your house. Try changing the wifi channel in your router settings (test channels 1, 6, or 11 on 2.4 GHz, which don't overlap) or force the 5 GHz band if your phone supports it, since it has less interference though less range.
What nobody has mentioned is using a free wifi analyzer, like Wifi Analyzer on Android or NetSpot. With that you can see which channels are saturated in your area and what actual signal strength reaches each spot. If you discover that other neighbors' routers are stepping on your channel, switching to a free one sometimes solves everything without spending a dime.
Now, if after clearing up interference and moving the router the signal is still crap, that's when you actually need to talk to your provider. An external antenna helps direct the signal, but if your provider simply doesn't have decent coverage on your property, the antenna only gives you 20-30% more range. Better to negotiate with them or try another provider before investing in hardware. If there's no alternative ISP where you live, an outdoor antenna + quality cable is actually worth it as a last resort.
If the signal drops specifically at night, the first thing is to check what frequency band your router is using - lots of them run on 2.4 GHz, which is more vulnerable to interference from other devices (microwaves, baby monitors, even LED lights). Switch to 5 GHz if your router allows it, or force that band in the settings. What others haven't mentioned: also check whether your provider actually has infrastructure in that area or if they're just selling you coverage that doesn't really reach well in practice - sometimes an external antenna won't help if the problem is coming from the provider's tower, not your router. Before you spend money on hardware, call the provider's technician directly and ask them to take a measurement on your property; if they confirm the signal does reach well but you're measuring low speeds, that's when it makes sense to try an external antenna or swap your router for a more powerful one.
Have you tried pointing the router toward a window facing the repeater or your provider's antenna? What nobody mentions is that router transmit power often comes limited by default in the settings, especially on 5 GHz bands, so go into the device's admin panel (usually 192.168.1.1) and look for the "transmit power" option and crank it up to maximum. That can give you a serious boost without spending a dime, and then you can decide if you actually need an external antenna or to switch providers based on how it works out.
If the signal drops specifically at night, try disabling 5GHz on your router and sticking with 2.4GHz only, which penetrates walls better and has less interference at those hours. And before spending anything on antennas, contact your provider directly to find out what real speed should actually reach your exact location, because sometimes they sell coverage that doesn't actually exist in practice.
The nighttime problem probably isn't just coverage, but don't go straight for an external antenna without first checking with your provider to see if they actually guarantee service in your area, because if the infrastructure doesn't reach there properly, an antenna isn't going to work miracles. In my case I had to move the router around several times and discovered that the material of the walls affected things way more than I expected, so try putting it in different strategic spots (high up, central location, away from electrical appliances) before you spend money. If it's still weak after that, then yeah, you need to contact your provider or consider switching operators, because sometimes one network is just bad in certain areas while another works decently.
The issue with the nights you're mentioning is weird if it were just range, but it could be that the provider is overloaded during those hours or there's interference from other equipment! I had something similar on my property and it turned out my neighbor had an old microwave that was interfering with the 2.4 GHz band, so I switched the router to 5 GHz and that was it, but the first thing I'd do is call the provider to have them run a real diagnostic of the signal in your area, because if it's not reaching properly from the start, an external antenna won't solve much.
If the signal drops specifically at night, something weird is going on beyond your router's range, so first document those changes: measure speed at the same time over several days in a row and share the results with your provider because a lot of times they tell you coverage reaches your place when there are actually limits or systematic drops they won't acknowledge. What nobody mentions is that an external antenna without moving the router itself almost never fixes anything; if you move the device to a higher, more central location and it still doesn't work, the problem is probably with your provider itself and not your equipment, so before you invest in hardware it's better to switch providers or negotiate with the one you have because external antennas only help if the base signal is decent.
