Most Common WiFi Issues:

This is when you are facing issues with your wifi router,

1. Speed is very slowThere are a number of reasons attributed to this problem,

Most routers work on the 2.5GHz band. So do Microwave ovens, cordless phones, garage door openers, baby monitors, and some other electronic devices. works on the 2.5GHz band – this is probably another cause why the problem has started. If so, turn it off and see if there’s an improvement.If that’s not an issue, keep in mind that the 2.5GHz band has only three real channels (1, 6, 11) despite pretending to have eleven (the others overlap with each other). Your neighbors who are WiFi-enabled are also using those same channels. so it is same as overloading a truck which only has a certain capacity.

A. Try to modify the channel your router uses (and subsequently any WiFi adapters), for that look through into the device’s setup controls (usually through a browser-based program that’s been installed on your computer when you installed the router or adapter) and manually changing it. (The default setting is where the problem can arise; vendors always pick the same channel.)

B. Add a 5GHz band component, such as Netgear’s WNHDEB111 networking kit or Linksys’s WGA600N to your present router. There are 23 channels available at 5GHz, and almost no one is using them right now. Switching to adapters is the most cost-efficient method because you’ll basically still be using your original router, but adding a 5GHz pipe to it through which you’ll funneling your WiFi devices.

C. You’ll need a pair of adapters. One is attached to a network switch to which you’ve also attached several of your PCs or other networked devices. The other is attached to your router. As far as your network is concerned, the devices on the switch are hardwired to the router. Practically speaking, they communicate through the 5GHz adapters and it’s the adapters that handle the transition down to 2.5GHz at the two end points — all the while communicating between each other across the 5GHz band.

D. Remember about 2.5GHz/5GHz routers themselves ( you need simultaneous dual-band models, those that can work on both 2.5GH and 5GHz at the same time, not either/or devices). This is a major investment because you’ve basically put yourself on the full upgrade path for your network and it’s not going to be cheap. Most of the major router manufacturers have such products. You have WiFi Router Repair support for dual-band models from SMC, Apple, DLink, Linksys, and Netgear here.

Upgrade Your Firmware  Another way is to try upgrading your firmware. The usual procedure is to:

Go to your router’s or adapter’s website and find and download a firmware upgrade if available. (If you use the setup utility that was installed with your router or adapter, you’ll be able to tell what firmware version you currently have. Just compare that to the “new” version.)
Once the new firmware is downloaded onto your PC, go back into the router’s or adapter’s setup through its utility software or your browser, find the management section, locate the firmware upgrade section in there, and just follow along.
It is that easy, but you may freak out thinking of all the possible things that might go wrong (like if you lose power during the upgrade…).


2. You’ve lost your passphrase and you can’t access all of your router’s feature.


This is a real trouble but not for long, and it’s not as bad as you think. If you’ve arrived at that point in the road where you once again need to access the internals of your router but never wrote down what your access passphrase was, relax. You can reset the device to factory defaults.

Most routers have a reset button recessed into the back of the case. It’s sometimes ringed in red but often it’s just an awfully small hole into which you must blindly poke a safety pin tip (or unbent small paper clip) so you can depress the recessed reset button for (typically) 3 to 5 seconds. (Don’t mistake it for the WiFi Protected Setup (WPS) button prominently placed, and usually labeled, on the front of your router).

The upside is that you’ll now have access to your router. The downside is that any settings you may have modified will now be back to their factory defaults and you’ll need to redo them. You’ve saved the manual that was supplied with your router so you can look up the factory default username and passphrase, right? In case you haven’t, the usual combinations of usernames and passphrases are admin/password and admin/admin. It’s better to call in a technician for person for this WiFi Router Repair.


3.  You have a dead spot in your home that your 802.11g router can’t seem to reliably reach.

If you’re not already using an 802.11n router and adapter, it might be time for the switch. There is no particular suggestion for that WiFi Router Repair yet, the hardware is locked down and any changes that are needed will be done to firmware –which you can upgrade.)

When a data stream arrives at your dead spot, it’s often been bounced off of too many walls, floors, and other obstructions to make much sense to your 802.11g or 802.11b router. A MIMO-enabled router takes all those bounced reflections and compares them, looking to fill in the blanks until it’s pieced together as much of the signal. It’s more than likely that the drop-outs you’ve experienced with your 802.11b/g router and adapter will be cured and you might actually see some honest WiFi speed emerge.

4. No WiFi SignalThough not a viable solution for many people because it is expensive and it also needs a lot of technical knowledge for this but the best and most recommended WiFi Router Repair solution is to run a CAT 5e cable between the two points,

Renters face another obstacle: Landlords who don’t want holes poked through their walls and ceilings. If you find yourself in that rather large group of folk, all isn’t lost. There’s always Powerline networking gear.

If you’re not familiar with the work being done by the Homeplug Powerline Alliance, check its website for the all the background. The gist of things is simple: You get two adapters. You plug one into an AC wall outlet near the equipment you want to network and the other in a wall outlet near your router.


5. No Internet ConnectionReorganizing your network topology to make best use of your wired and wireless connections is always a good thing, but changing something that’s working can often lead to unintended consequences during WiFi Router Repair. Assuming that everything is plugged in as before, your router may not be at fault. If you have a local connection but no Internet connection, it could be your modem. Some modems have parental control buttons that, once pressed, lock out your internet connection. They’re not always in the best locations.

How to Fix Your WiFi Network

If your laptop is having connectivity issue then not only your router but your laptop also needs troubleshooting for computer Router Repair,..

1. Check Your Laptop for a WiFi Button or Switch

Sometimes  when we miss the fun inside a free hot-spot zone like coffee shops or airports due to connectivity issues of your router. The problem is really easy to diagnose. If your laptop or netbook isn’t connecting to a local wireless router at all and you can’t view a list of nearby wireless networks, check to see if your laptop has a WiFi button or switch that you may have pressed accidently. Many laptops include a function button (labeled with an icon representing a wireless router or network) on the top of the keyboard or a switch on the front or sides of the laptop. If you find such a button, check to see whether pressing it enables you to get connected.


2. Reboot Your Computer and Your Wireless Router

If the connectivity issue still persist then the next thing to do is to reboot it. This step sounds simple, but your router, your PC’s WiFi adapter, or your operating system may have a software or firmware problem that a simple reboot would fix.  In case a series of devices show the same disconnecting issue , try unplugging the router for 5 to 10 seconds and then plugging it back in. This technique of “power cycling” your router is a tried-and-true method for restoring a previously functional wireless network to good working order.


3. Change the WiFi Channel on the Router

this is very crucial and complicated step, better to get assisted by an expert for this WiFi Router Repair. Most WiFi routers and devices use the 2.4GHz radio band. Unfortunately, only 3 of the 11 channels can run simultaneously without overlapping or interfering with each other: channels 1, 6, and 11. Worse, many routers are set to broadcast on channel 6 by default. Consequently, interference from other routers in the vicinity is a common source of connectivity problems, especially in densely populated areas such as apartment complexes and shopping centers. Other radios that use the 2.4GHz band–for example, baby monitors and cordless phones–and other electrical devices (such as microwave ovens) can interfere with WiFi signals, too.

To see if other wireless routers might be interfering, take a look at the list of nearby wireless networks. If you’re using Windows, click the network icon in the lower right corner. If you see other network names, especially those with more than one bar of signal, they could be interfering with your signal.

for further WiFi Router Repair you can try to dodge interference by changing your router to another channel. You can blindly choose a channel (going with 1 or 11 is probably your best bet) or you can make a better-educated selection by checking to see which channels nearby networks are using so you can use a different channel. You can check with a free program like InSSIDer or Vistumbler, or use the Web-based Meraki WiFi Stumbler. If you don’t have access to one of these applications on your laptop, you can use a free app like Wifi Analyzer (on Android devices) or WiFi Finder (on Apple iOS devices) on your smartphone or tablet to scan for WiFi networks.

Once you’ve decided on a channel to switch to, you’ll need to log in to your router’s control panel and change the channel. To access the router’s Web-based control panel, open a new window in your browser while you’re connected to your router’s wireless network and then type in its IP address (most commonly or

If you don’t know your router’s IP address, refer to the wireless connection details: In the lower-right corner of your Windows desktop, right-click the network icon and open the Network and Sharing Center. Select the wireless network that you wish to view, and click the Details button. You should now see the router’s IP address listed as the Default Gateway.

Next, log into your router control panel with the appropriate username and password. If you don’t know the password, you may never have changed it–so try the default password, which you can look up on RouterPasswords.com. If your Internet service provider supplied your router, you may have to call your ISP for help in accessing the password.

After logging in to the router, find the wireless settings and change the channel. Many routers have an automatic channel selection feature; if yours does, you can disable it and manually choose a channel. Again, for maximum performance, try to stick with channel 1 or 11. Once you’ve saved and applied the settings, your router may reboot; if so, reconnect and then check to see whether your connectivity problem persists. If so, you may need to try another channel.

4.Check and Reposition the Wireless Router

If the connection difficulty seems to arise only when you’re rather far away from your wireless router, the problem could be that you’re on the fringe of the router’s coverage zone. The simple way to fix this is to buy a router with better range, but you can take some other steps before going to the trouble (and expense) of buying a new router. First, make sure that your router’s antennas are securely attached and are positioned upright. Next, confirm that the router isn’t buried or blocked behind large objects that might cause the signal to degrade faster than it normally would. For best results, place your router out in the open so the signal can travel freely.

If you still aren’t getting the WiFi range you’d like, consider moving the router and the modem to a more central location within your desired coverage area. Of course, your placement options are limited: The router must be near another cable or telephone jack. Most cable modems can plug into any cable outlet, and DSL modems usually plug into other telephone jacks–but remember to switch out any filters that might be attached.


5. Troubleshoot Wireless Router Problems
Like any other electronic device routers can be damaged by overheating . This overheating kills the router over time or just make it unstable. Check your router’s temperature to see how hot it is. If it seems very hot, ensure that it’s getting enough airflow. If the vents are blocked or you have the router in a hot location — like on top of a tower PC that heats up — overheating could be causing instability. It’s also possible that past overheating may have damaged the router.


6. Verify Cables Are Securely Connected

This is very silly  but we mostly forget to try out simple solutions before getting into more complicated ones. Even if someone has pulled on or kicked a cable, causing it to unplug or become loose.  It’s the first thing to do off course to check all of the cables involved and ensure that they’re securely connected.
Be sure to check the power cables to your router and modem, the cable between your router and modem, the cable between the modem and the wall socket, and each Ethernet cable plugged into the back of the router. Check each end of the cable and ensure it’s securely connected — it could look connected but be a bit loose.


7. Reset Your Router to Factory Default Settings

You may want to try resetting your router to its factory default settings if there seems to be a serious problem for WiFi Router Repair with its configuration. This shouldn’t be necessary in most cases, but it’s worth a try if you’re at your wits’ end. It’s possible that you’ve changed certain settings on your router that you shouldn’t have, and it may be easier to revert to a clean slate rather than changing the individual options back.Bear in mind that you’ll have to reconfigure your router after this, including setting up your wireless network name and passphrase again. You’ll likely need to long-press a Reset pinhole button on the back of the router to reset its settings, but the exact details will vary from router to router. This is the same process you need to perform to reset your router’s password.
